Determining the length of a driven element
by Phil 25 Aug '08

25 Aug '08

Hello, During a casual conversation recently, the topic of aerial trimming came up. Perhaps this may be a little off-topic here but since I don't know the answer I thought this would be a good place to ask anyway. Say a dipole has an SWR of 5:1 at one end of a band and 4:1 at the other end. Further, let's say that the dipole will be used at the centre of the band and with a reasonable SWR. It has been determined that the dipole needs to be shortened. The question is by how much? The person asking the question is reluctant to pull the aerial down a dozen times so that short lengths can be nibbled off each end and instead wants to know if the amount that needs to be cut off can be determined from the difference in the SWR at both ends of the band. A logical question I suppose but is there a reasonable answer? -- Regards, Phil

Wow what an idiot. Got already to do VO-52 for the first time a half hour ago,,, checked the time, checked the azimuth, tuned the IC-910H to freq... I could hear lots of stations... but could never hear myself. VERY frustrating. Started from scratch after the pass. oh. 435 mhz.... I had it on 432 mhz... duh.

more SSB satellite experimenting (23 August)
by Patrick STODDARD (WD9EWK/VA7EWK) 24 Aug '08

24 Aug '08

Hi! Today, I planned to spend most of the morning at a city park in north Phoenix (a park straddling the DM33/DM43 grid boundary) to try a few passes on DO-64 and VO-52. I also worked an AO-51 pass using my all-mode setup (two FT-817NDs with Arrow Antennas handheld 2m/70cm Yagi), before those SSB birds started making their morning passes here - and before it reached 41C/106F outside! The DO-64 pass I tried first was about 22 degrees maximum elevation to the east. I could hear the beacon, and could hear my CW going through the transponder. I could not hear myself when using the mic. Since the second pass to the west was about the same elevation, I didn't try it. I was on VO-52 for two passes, both passes having maximum elevation in the 20-25 degree range. I heard a couple of stations in SSB on each pass, I was able to hear myself call CQ a lot during each of the passes, but logged no QSOs. Since I am not using computer control, I have tried not to park near the center of the passbands on these satellites. Specifically for VO-52, I have tried to park around 145.910 or 145.915 MHz on the downlink as not to interfere with others around 145.900 MHz using full computer control. Unfortunately for me today, nobody ventured up to find me during the passes. During the second (western) VO-52 pass around 1825-1840 UTC, I started reducing my power as I called CQ. The FT-817ND has 4 power levels, and I went down from the high power (5W) setting to the lowest level (500mW) and could still hear myself clearly through VO-52. Antenna polarization was more important as the power level went down, in order to get to and through the transponder. I had to twist my Yagi around more, to make sure I could make the round- trip to the satellite. This is a good thing, as now I know I can use a lower power level if I am operating with only the FT-817ND's internal NiMH battery pack. I normally use one of my two 12V/20Ah jumpstart battery packs to power my two FT-817NDs or (for the FM birds) my IC-2720H when on the satellites. Since next weekend is a holiday weekend for the US (and Canada), I hope to be on VO-52 and maybe DO-64 during those 3 days. I might try AO-7 if there is a high pass in my area as well. If you are on during those passes next weekend, please feel free to tune up the passband. Please be patient with me, as I am not set up for computer control on my radios - yet. If things go well, I will do some demonstrations on VO-52 along with the 3 FM satellites during the upcoming ARRL Southwestern Division convention here in the Phoenix area on 12-14 September. 73!

"Solar Cycle 24 Canceled - Ham Radio OperatorsFurious" Date: Sun, 24 Aug 2008 00:13:22 +0000 Printed from: http://www.thespoof.com/news/spoof.cfm?headline=s5i39491 Solar Cycle 24 Canceled - Ham Radio Operators Furious Written by drugtestallpoliticians Dayton, Ohio (IPP) - The next solar cycle was assigned the number 24 but has been canceled by the International Astronomical Union (IAU). Scientists were able to predict that this cycle would have been 30% to 50% stronger than the previous solar cycle and it would have started a year later than previously thought. Scientists have been unable to accurately predict the intensity of future solar cycles until recent times. All of that changed recently when the Predictive Flux-transport Model was developed and put into effect. This new method is thought to be 98% accurate. Dr. Povenmire Finootch of the Mount Palomar Astronomical Campus and the senior legal representative of the IAU takes full responsibility for canceling the next solar cycle and has a black eye to show for it. He recently got into a scrap with the head of the North American Ham Radio League, Brent Brookski over the canceling of solar cycle 24. Dr. Finootch claims that the IAU has complete authority over anything related to the visible as well as the invisible portions of the electromagnetic spectrum. Ham operators take advantage of the increase in solar electromagnetic activity by bouncing radio signals off of the ionosphere to each other in the form of radio waves which are transmited via upper and lower sideband and cw ( continous wave or morse code). When the solar cycle is in full swing it is possible for a Ham operator in North America to talk to his counterpart in New Zealand using a mere 5 watts. Dr. Povenmire Finootch admits that he has a black eye but that nevertheless he had thoroughly throttled his opponent during a fist fight they had during the Gay Ham Operator's Convention (GHAC) in Key West last week. The two had become embroiled in a fierce argument over whether or not the IAU had any business sticking its nose into the business of Ham operators and this argument evolved into fisticuffs to the delight of nearby bar patrons. Dr. Povenmire Finootch seemed to go over the edge when Brookski claimed that Dr. Finootch would not know the the difference between Ohm's Law vs Kepler's Law if it "bit him on the ass". Dr. Finootch replied, "Neither would you then !" Dr. Finootch did not realize that the Ham operator had a well concealed "hair lip" under his moustache and the Ham operator was equally unaware that Dr. Finootch had a wooden eye. The Ham operator had responded by saying, Woudn't I, Wouldn't I" to which Doctor Finootch had replied, " Hair lip, hair lip !" And thus the fight was on.

Re: COMPASS over ZL

Hi Mike, Compass seems to be back to its normal self this morning. All commands sent and acknowledged at 2005 UT. No beacon heard. Hi Bob, You asked what others are using. I am also using the TS-2000X. I have the tones programmed into the DTMF tone memories with the tone speed set to "Slow" (100ms tone, 100ms space). The uplink antenna is a 10 element crossed yagi and the downlink is 19 elements. I also tend to use up to 100w for very low elevation commands but above about 8 to 10 degrees 20w is OK. I have preamps at the antenna but don't use them for Compass - the response is good and solid here without the preamp. Beyond that I use automatic az/el and Doppler tracking using home brew software and make sure that the Doppler correction keeps my uplink signal exactly on 145.980 at the satellite and my receiver on the 437.275 downlink. I tend to wait until Compass is a few degrees clear of my horizon before sending the commands. If my first command is not acknowledged I switch (linear) polarization and that usually works. 73's Alan ZL2BX -----Original Message----- From: Mike Rupprecht [mailto:[email protected]] Sent: Saturday, 23 August 2008 14:32 To: 'Alan Cresswell' Cc: 'Robert Smith' Subject: AW: [amsat-bb] Re: COMPASS over ZL Hi Alan, Robert Thanks for your report.

Hey everyone, I'm preparing a presentation on the three LEO satellites currently active in Mode J, and I'd like to include the physical dimensions of each. I need some help in that regard: The AMSAT Web page on AO-51 lists it as 150x150x150. The page for AO-27 lists it as 25x25x25. Can anyone tell me the correct unit(s) of measurement for each? SO-50's dimensions are not listed. Does anyone know what they are? Thanks in advance for any help you can provide. 73, Tim - N3TL

IC-T7H users on Mode-J satellites?
by n3tl＠bellsouth.net 23 Aug '08

23 Aug '08

Hey everyone, Is anybody using an Icom IC-T7H HT to work passes of the Mode-J LEO satellites? Icom's literature reports a receiving mode on this radio "similar" to the dual-watch function on some of its other HTs (e.g., IC-92AD), which ought to make it functional as a non-full-duplex option for AO-27, AO-51 and SO-50. Any help on this will be greatly appreciated. Thanks! Tim - N3TL

Re: HRD Satellite Tracking - Technology Preview
by David 23 Aug '08

Simon, Before downloading and trying it out can you tell me if the satellite tracking program works without having the radio(s) connected? One of the original versions of HRD that I used allowed me to check passes etc without the need to have the radio in line - the latest version was inoperable unless the radio was there. I stopped using HRD at this point although the well documented problem with the non- functioning Doppler compensation control was another factor.

Hi Mike... It always puzzled me why in your original list of commands you suggested the following 2 commands one after the other: ****14#200# heater off to -55 degr THIS IS THE VERY IMPORTANT COMMAND ****13#200# heater on to -55 degr It would seem to me that command 1 turned the heater OFF and then command 2 just turned it back ON AGAIN! .... Maybe you were just using "shorthand" and something else happens when you issue these commands one after the other? Thanks!

QSL cards from WD9EWK's 17-22 July 2008 road trip

Hi! I now have blank QSL cards for each of the 10 locations I transmitted from during my 17-22 July 2008 road trip. For this trip, I am not using the AMSAT AO-7 30th anniversary "fill-in-the-blank" QSL cards that I've used in the recent past. I have cards with information for each location including an image of my GPS receiver's display showing the latitude/longitude for each location. I have already replied to the QSL requests I received at my PO box since the trip, plus I've sent out cards to others who have asked for cards to confirm contacts during my trip. I'll write out more cards this weekend, to go in the mail early next week. If you worked WD9EWK during that period and would like to receive a card (or cards) for any contact, please e-mail me directly with the QSO information. If you want to send me a card (or cards), that's OK. You don't have to send an SASE or stamps. I appreciate any SASEs or stamps I receive, as that helps cut down my contribution to the US post office this month. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

Thanks to all that i've worked, both in Europe and state-side. Not traveling solo, it's been hard at times to be both available and have a good horizon for trans-Altlantic passes. Half the time, no one has been on! But they have been alot easier to work than those over Europe. I'm experiencing lots of QRM soon after the bird goes overhead on morning AO-51 passes and people calling CQ who can't hear the bird. But on less busy passes, i'm making contacts and hope to talk to more of you from mainland Scotland. Internet access has been sparse but you can suggest a sked and i'll respond if i can. Hope to talk to more of you, especially across the pond, from now until roughly September. 73's and good luck! -- KD6PAG

So to get a beacon is just a matter of luck if it beacons while over head. sounded powerfull though, will be looking for it the next pass's. kc8gkf p.s. had to change freq from 437.275 to 437.405 for the packet. wish they were on the same freq. guess I have to decide what one i want to try for. anyone know how they xmit us the pics? or if any pics have been downloaded as of yet?

DO-64 observations
by WILLIAMS MICHAEL 22 Aug '08

22 Aug '08

These is my personal observations about DO-64. The descending (morning) passes seem to be LHCP. My down link antenna is fixed LCHP only, and I hear the descending passes really well and can access DO-64 easily even at low elevations. Above 45 degrees, DO-64 is loud and I can back off power < 5 watts CW. Up link antenna is a 11 turn helix RHCP. The ascending (evening) passes are very weak. Probably RHCP as I am fixed LHCP. At this time, DO-64 is not in sunlight on the ascending (evening) passes over the central U.S. The beacon at 145.870 is easily heard. When you hear the beacon, you can put a signal through the transponder. 435.556 MHz up puts you real close to the center of the 40KHz wide transponder and 145.900 MHz down. DO-64 does not have the booming signal as VO-52. I think I remember from the video that the transponder output is 200 mW. On the first half of the pass, the signals seem to be much stronger than the second half. It is a challenge and fun to work through this sat . This no battery satellite is a good idea.

AO-51 V/S Mode Ops, Some Observations
by Robert Felt 21 Aug '08

21 Aug '08

Thanks AMSAT for placing the AO-51 is V/S mode last week. It was the first time I have operated any S-band downlink. The AO-51 was really quiet on S-band downlink, not a lot of people yelling on top of each other and background noise was nil. I made some good QSOs including - N8BBQ, WB8OTH, N5UXT, N5AFV, KD8CAO, N8TLV, N5ZNL... and heard a lot more, but was too focused with the doppler to make contact. My station : On the receive side I am using a home brew antenna based on a 36" "BBQ" grill with a 5 turn helix feed, connected directly to a model UEK-3000 down converter (by SSB) , into my AOR AR-5000A3 receiver. The transmit side was with my Icom-910 into a 11 element yagi. Antenna: My old Kenpro 5400 rotator was controlled through the LVB interface using NOVA software on my laptop. I used the frequency utility in the NOVA s/w to calculate and display the doppler on the down link, which varied from +50 to -35 KHz on most passes!! The doppler really keeps you busy on S-band, as there is no CAT output (just display) on the NOVA software, and you have to crank in the doppler manually. NOVA tracking software is very powerful and user friendly, but lacks radio CAT output. I would like to someday find a software program with the same or comparable look and feel as NOVA, but with CAT rig control interface in addition to the standard rotator interface. (SATPC is ok but has the look and feel (GUI) of an old 1980s DOS program). Is there a good CAT program rig control that I can run in the background while running NOVA for ant control and display? Anyway, Thanks AMSAT. Lets do this again some day. 73' de KB5YZG Bob Felt 1403 5th Ave West (EM85) Hendersonville, NC 28739 email - kb5yzg(a)amsat.org

Re: Compass over ZL
by Alan Cresswell 21 Aug '08

21 Aug '08

Hi Mike and Robert, All commands sent and accepted at 2102 UT. A test beacon was received 5min and 40 seconds after the test beacon command. A normal beacon began 3min and 40 seconds later but unfortunately Compass was at zero deg elevation when the beacon began. I have a -1 deg horizon in this direction so managed to get part of the frame as follows: FF18090011710020........(LOS). The 11 in the middle was very noisy but almost certain they are OK (Definitely 1 or 0) and just managed to confirm that the heater was off before it went into the noise! At least the system is up and running - good signal strength from the test beacon.

Florida AMSAT Net
by David J 21 Aug '08

21 Aug '08

Good Day Everyone, For those of you that usually check into the Florida AMSAT Net at 19:30 ET on Thursdays through the N4HHA repeater in Orlando, the repeater has a new controller installed and appears to be working fine. I haven't had a chance to speak with Mike about it, but I believe it is capable of linking to the NI4CE repeater system as usual, so tonight's net should go off without a hitch. I won't be net control tonight due to water in my coax from Fay and a very high SWR. I be present using a weak indoor antenna just to check in. K4ACB has agreed to handle it tonight. See you on the net, Dave, AA4KN

Compass sounding better
by Bob DeVarney W1ICW 21 Aug '08

21 Aug '08

Mike, on the 14:10 pass over the eastern US, I was able to upload the heater off and test beacon commands several times successfully. I also heard confirmation tones several other times during the pass, so others are also able to get into the satellite. I commanded the test beacon several times and got confirmation, but never did hear the beacon come on during the pass. Perhaps because so many people were sending commands at the same time, it just kept resetting a timer. I believe Compass is getting healthier; it certainly seems a LOT more responsive today than it was, say 4 days ago. I think this is encouraging. Hopefully someone can get a beacon out of it this pass. I wlll be listening up for the 15:43 pass and hope to hear a beacon then. 73 de Bob W1ICW

re polarity control (woops!)
by Angus 21 Aug '08

21 Aug '08

Hi, think I finally found out why there was not as great a difference on the LHCP compared to RHCP or so I thought and yes it was operator error (you guys already knew that I think hi). Problem was I was using NOAA satellites as my signal source for a RHCP and when I switched to LHCP could still hear them well. Truth of the matter is the signal here on RHCP is massive around 59+40db on a normal pass, when I switched to LHCP the signal was still BIG (59). So the truth of the matter is, there is a huge difference to my RHCP and LHCP but I should not have used such a large signal as a reference source. I realized what might be the error and checked it by sending my 14 year old son Cameron (2E0BAU) out on a 10 mile bicycle ride with a Yaseu VX2r handheld and a small yagi (similar to arrow). having got to a nice high spot, he pointed the yagi in my direction, he then spun the yagi slowly in a RHCP everything was fine (around 0.1watt output from VX2r) but when he spun the yagi in the wrong sense he was a very poor signal. So now I have got that sorted, I am happy but sadly Cameron is not, very heavy downpour on his way back home on the bicycle, got very wet!

LMR400 or 400UF?
by Michael Tondee 20 Aug '08

20 Aug '08

I need to rework my 70cm antenna system and was thinking about going with LMR 400. I have about a 40 foot run. Is there any real advantage to using the ultra flex for the entire run or can I get by with a short section of the UF between the preamp and antenna to accomodate the rotor turning? How about just using a short section of RG8U there instead of the LMR400UF? I'm trying to do this on a budget. Tnx and 73, Michael, W4HIJ

I am going on a trip that will pass through some rare grids. It is not a grid expedition and the main purpose is work related travel. The person I am traveling with has agreed to a few "rest stops" for me, my hand-held and arrow antenna. I cannot guarantee exactly when I will be in which grid, but I will leave Watertown, SD Sunday, August 24th around 6:00 AM. My trip will take me through the following grids EN-15, EN-05, DN-95, DN-85, DN-86, DN-76, DN-66, DN-65, DN-55. I will cover the same ground in the other direction August 29 or 30th. Please listen for me on AO-51, SO-50, and AO-27. I don't expect to make every pass, but I hope to get quite a few of them. 73, Joe kk0sd P.S. If you really need EN-15 or EN-05 they are not that far from my home and I would be willing to do a sked.

COMPASS-1 needs your help
by Mike Rupprecht 19 Aug '08

19 Aug '08

Hi all, The recent events are dramatically. Our two ground stations are almost inoperable. A few days ago however, a hard-reset of the satellite had occurred, which brought the satellite back into the following vicious circle: Once the heater is being switched on, the battery power drops drastically, which causes another hard-reset. This goes on and on. The only chance to recover the satellite is to avoid the activation of the heater. This can be done by adjusting threshold values. Since these values are reset after each hard-reset, we would need to send them again and again, until the satellite is in a stable condition (batteries charging), where no reset occurs. Thus, if you would like to support this recovery phase and have the right equipment to do so, please upload the following DTMF tones to COMPASS-1 (simply from loudspeaker via microphone) THRESHOLD ADJUSTMENT (to do after every hard reset) ****14#200# heater off to -55 degr THIS IS THE VERY IMPORTANT COMMAND ****13#200# heater on to -55 degr ****16#170# critical batt threshold to 3.3V ****15#255# low batt threshold to max -> charge batteries The commands consist of 4 stars, two numbers, a hash, 3 numbers, and a hash. If COMPASS receive this sequence successfully you can hear a short confirmation beep. There is an good and free DTMF dialer to download here: <http://www.polar-electric.com/DTMF/Index.html#Encoder> http://www.polar-electric.com/DTMF/Index.html#Encoder Uplink: 145.980 MHz FM Downlink: 437.275 MHz CW If you have any questions, please ask me.

Scotland & Shetland Islands
by John Mock KD6PAG 19 Aug '08

19 Aug '08

Greetings from the Shetlands. Passes over the East Coast weren't feasible from Glasgow and the one that i tried here yesterday had no one on. I will keep trying. I've worked about a half-dozen continental passes and SO-50 has been both crowded and noisy. Morning passes on AO-51 have been much better and i can hear myself well at 140mW in the early parts of the passes. But can't even hear myself at all over the QRM between QSOs at 2W when AO-51 gets very far south. I've worked several stations but many others don't seem to hear me (or maybe even each other). If i'm trying for the East Coast, it will likely be AO-51 passes over the Atlantic and possibly on SO-50 around dinner EDT. I will continue to try European AO-27 passes in the morning as time permits. I hope to work you. 73's and best of luck! -- KD6PAG

TS-2000 sensitivity mod-production years?
by Mark L. Hammond 18 Aug '08

18 Aug '08

Hello all, There has been a few posts lately about the "sensitivity mod" for the TS-2000 radio--but it seems like there was a point when Kenwood may have "fixed" the issue. Does anybody know the production year, or serial number ranges, that apply to radios needing the "improvement"? I've always thought mine was a bit deaf, esp. on 2M. I bought my TS-2000X in early 2004...my serial number starts with 509. (I just performed the mod, but I'm not sure I can see an improvement--but haven't been able to test it on a bird yet). Thanks!

DO-64 observation
by Luc Leblanc 18 Aug '08

18 Aug '08

First experience with do-61 (DELFI C-3) this morning here. 1-No body was on the satellite only me calling CQ 2-From AOS to TCA signal was very good about +-3 DB above noise level 3-At TCA signal dropped below noise level too week for SSB but week for CW 4-From TCA to LOS signal remain below noise level and became too weak even for CW I suspect the satellite antenna configuration show some directivity or it is the satellite attitude who seems to favour some part of the orbit pass? I was never able to received my SSB dowlink on the eastern pass only a week CW carrier one time. There is some audio AGC as increasing the audio level make's not a big change on the dowlink. I was able to uplink with the FT-847 RF gain control completely turned off (about 1 or 2 watts). I don't know if my results are in line with what the team planned but when the sat was on data mode i was able to copy it from AOS to LOS but i think the TX power is reduced in transponder mode? It make's another one to experiment with and a preamp is imperative to be able to work it with ease. Just have to get some folk's on it here to be able to check it again.

Yes,, BUT,, it may be good enough for a low sreq radio signal, but in this casting they still had to make the reflecting surface the same old way, grinding with grits, to even out the surface,, then polish it, then paraboloze it. all the spin casting does it take the "Rough Grinding" portion out of the process, since 90%+ of the concave shape is raedy.

Hi all, good news ! Tetsu (JA0CAW) heard the beacon at 00:23 UTC over Japan ! A great thank especially to Alan (ZL2BX) who switched the heater successfully off for 3 times (at 1946, 2124 and 2302 UTC), Sion (9W2QC and Bob (W1ICW). And of course to all who tried her best - thanks for your time and support. This is a good sign, that the batteries will be charged. Please continue to send the 4 commands to COMPASS whenever you hear the beacon or COMPASS is in full sunlight. Let's hope the recovery efforts are a success! Respectfully, Mike DK3WN Dear Mike The mail that I sent Compass Team is sent. 73 JA0CAW(Testu) ************************** Dear Kevin COMPASS-Beacon Report I heard the Compass Beacon what Beacon might.

COMPASS-1 beacon
by Mike Rupprecht 18 Aug '08

18 Aug '08

Hi all, If you hear the COMPASS-1 beacon on 437.275 MHz (CW) please report your results to us. There is a simple decoder to download here: <http://www.dk3wn.info/files/compass.zip> http://www.dk3wn.info/files/compass.zip compass ff073900070300210000a300ff ^ this "1" means - heater ON In this case you can try to send the important command ****#14#200#. And the other ones as well.. COMPASS is in emergency mode - so the beacon comes every 8 minutes. Please listen and have a little patience :-) Thank you very much for your efforts, 73, Mike DK3WN

Hi Mike, No problem. I will try the test beacon command on the two good passes tomorrow. (14 deg and 58 deg.) I assume you still want me to send the other four commands as well. I will be away for the third pass tomorrow but it is only 4 deg anyway. I should be OK for all other passes for the rest of the week. Alan ZL2BX -----Original Message----- From: Mike Rupprecht [mailto:[email protected]] Sent: Monday, 18 August 2008 05:54 To: Alan Cresswell Subject: Re: [amsat-bb] Re Compass-1 recovery efforts Hi Alan, I can not say enough thank you so much for your time. It is unclear why we get an confirmation but no beacon is sent. The confirmation comes from the internal TTC. The beacon is commanded from EPS to the TTC. So you could try to request a test beacon. This is the code: ****35## The beacon text is: 00 dp0com-compass-1-012345-compass-1 This beacon is also controlled by the TTC. It could be that the internal system bus (I2C) is down and in case we have no internal communcation. Maybe the low voltage is the reason. So if you have a good pass (and you have the time) in full sunlight you can try to get an testbeacon.

WG: Compass-1 recovery efforts
by Mike Rupprecht 17 Aug '08

17 Aug '08

Hi Bob and all, thats really great - good news :-) Now we have 3 successfully contacts. But it seems, the battery voltage is too low for the beacon. The only thing we can do is to try it again and again - and waiting for more illumination (end of august). Every reset of COMPASS will set the initial values and the heater will be switched on. So we need a good pass and switch the heater off when it came out out the eclipse. Maybe the time until the next eclipse is long enough to load the batteries and COMPASS remain alive during the next eclipse. Thank you very much for all your efforts. I am so glad that we have friends around the world :-) 73, Mike DK3WN -----Ursprüngliche Nachricht----- Von: amsat-bb-bounces(a)amsat.org [mailto:[email protected]] Im Auftrag von Bob DeVarney W1ICW Gesendet: Sonntag, 17.

more poking around SSB satellites (16 August)
by Patrick STODDARD (WD9EWK/VA7EWK) 17 Aug '08

17 Aug '08

Hi! Yesterday, I took my portable SSB satellite station (2 FT-817NDs with Arrow Antennas dual-band Yagi) to a park here in Phoenix on the DM33xp/DM43ap grid boundary: http://maps.google.com/maps?f=q&hl=en&geocode=&q=33+38.933+N+112+0.00+w&ie=… For the time being, I consider this location my "home QTH" when working satellites. A nice open area, plus being right on 112 degrees West doesn't hurt. I did not wake up early enough to try AO-7 during the morning passes, but I planned to try DO-64 (Delfi-C3) and VO-52 again in the late morning. Later in the day, I tried an AO-7 pass to the east. Mixed results, and a good day - other than the 104F/40C heat and humidity. I first tried a high DO-64 pass at 1727-1741 UTC yesterday morning. About 3 minutes into the pass, I could clearly hear the CW beacon. I did not try to copy the telemetry, but did hear "DELFI" coming through - confirming I was listening to this satellite. No S-meter movement on my receiver, noticeably weaker than VO-52, but workable. I then tried to hear myself through the transponder. Success! Again, signals through this satellite are weaker than VO-52, but for my portable setup I do not need a preamp to hear anything. I heard one other station, a W6, and then I proceeded to pick a spot to camp out and call CQ. I set up so I would be on/around 145.910 MHz USB on the downlink. It did not take long to hear myself transmitting through the satellite. I called CQ, and - unfortunately - only heard myself for the remainder of the pass. A suggestion... since AMSAT is now distributing keps for this satellite in the weekly keps e-mails, why not put this satellite on the web site's pass- prediction utility? I will definitely try for this satellite again, hoping to make some contacts through it. A few minutes later, VO-52 was coming by. Again, a high pass, at 1750-1803 UTC, and I went to work. Calling CQ so I could hear myself around 145.910 MHz USB on the downlink, Ken N6KTH responded a couple of minutes into the pass. We had a nice chat, longer than possible on most FM satellite passes. Ken - sorry if I was drifting around a bit; I was trying to hold my downlink steady and make any tweaks on my transmit frequency. After working Ken, I moved up to 145.915 MHz and called CQ for the remainder of the pass. Glenn AA5PK found me in the last couple of minutes of the pass. We had a quick chat - the satellite was almost out of range for him, and I had about 2 minutes left before I was out of range. In the late afternoon, I returned to the same location to try for AO-7 on a 20-degree eastern pass at 0042-0100 UTC. I forgot that, with my portable setup, I need to look for AO-7 passes with high maximum elevation to hear it with my setup. Last month, I was able to hear AO-7 passes with elevation above 40 degrees. I know that a preamp might help me in this area, but I'd rather take the time (and expense) to have computer control of at least my radios before looking for a preamp. I will try AO-7 again, another time. Some details on my FT-817NDs... both have the TCXO module, both also have the 500Hz CW filter (I also have an SSB filter at home, but with only one filter slot it's more important to me to have that CW filter in place), and I usually transmit at 5W. I bought my first FT-817ND in May 2004, and the second one 3 months ago when I decided that my AOR AR8200Mk2B receiver didn't tune SSB in small enough steps for my first attempts with the SSB satellites. I run both of the radios from a 12V/20Ah gel-cell battery, or I could use the internal NiMH battery packs in each radio (both at 9.6V, 1400mAh in the older 817 and 2000mAh in the newer 817). I have been using the newer 817 as my transmit radio. I'm getting comfortable enough with VO-52 and its powerful downlink, that I will probably include VO-52 in my hamfest and other satellite demonstrations I do. DO-64 could also be on that list, once I make some contacts through it and there are stations on those passes on a regular basis like VO-52. I might continue my focus on FM satellites during road trips, but when I'm not on the move I will try to add the SSB birds to my activities from unusual locations. :-) 73!

G-5500 7806 regulator question
by Mark L. Hammond 17 Aug '08

17 Aug '08

Hello All, It appears that the 7806 voltage regulator in my Yaesu G-5500 control box has gone bad; the output is measuring more like 10.8 Volts (!). This explains why both position indicators were off by a factor of 2 (e.g., elevation meter showing 90 deg, array pointing 45; azimuth meter showing 180 deg, but array pointing 90 deg., and so on). Question---has anybody used a 7805 to replace the 7806 regulator in this control box? I don't have a 7806....so this brings the next question--anybody have a 7806 (or 2) that they want to sell?) Thanks, Mark L. Hammond [N8MH]

One attract my attention was made by Peter Guelzow DB2OS one one of his slide we can read: ATTRACTIVENESS OF AMATEUR RADIO HAS DROPPED SIGNIFICANTLY FUNDING A SATELLITE FROM AMATEUR RESSOURCES ALONE NEVER WORKED BEFORE AND WILL NOT WORK NOW. I don't how to explain how all the wisdom and reality knowledge seems to be concentrated in Europe when speaking about amateur satellite? Could be we are too stupid here and we swallow anything "the official" says but with the figures given 3.5$ millions can be reached in 3 years by 6000 supporters at a contribution rate of 200$ per year. I know figures was given in pounds but it is achievable if one day or another the AMSAT'S regroup under an unique satellite funding structures any goals will be achievable. It's true that "FUNDING A SATELLITE FROM AMATEUR RESSOURCES ALONE NEVER WORKED BEFORE" but the context never evolved the same AMSAT'S pattern remain as if it was the only one TRUE solution...It's not. OPINION POLL AND SURVEYS I start one "unscientific" couple years ago AMSAT-NA make one more scientific...too and the last one show up the very same results the amateur community want's by a very strong margin HEO'S. The cube sat concept is already very well served by all the cube sats group. It will be logical NOW that the NON CUBE amsat's refocused their goals on HEO'S. It should be their primary goals not making cube sats as they are cheaper to construct and launch but making or financially/technically supporting the most viable actual HEO'S project eg: P3E.

August 17, 2008 To All RADIO AMATEURS BID: $ANS-230.03 Since Sunday, the COMPASS-1 CubeSat has been in emergency mode. The battery voltage is very low and the satellite is rebooting every pass. The CW beacon is on in sunlight - but it only transmits on 8 minute intervals. A hard-reset of the satellite has occurred, which brought the satel- lite back into a vicious circle: Once the heater is being switched on, the battery power drops drastically, which causes another hard-reset. This goes on and on. The only chance to recover the satellite is to avoid the activation of the heater. This can be done by adjusting threshold values. The COMPASS team needs as much telemetry as possible. Amateur radio stations around the world are asked to listen to the COMPASS down- link on 437.275 MHz. Any reports will be appreciated. You can find a simple CW telemetry decoder at: http://www.dk3wn.info/software.shtml. MP3 or WAV files would also provide useful information.

Re: G-5500 7806 regulator question-update
by Mark L. Hammond 16 Aug '08

16 Aug '08

Okay, thanks to all for the quick suggestions!! I forgot about the trick of using a diode (or two) on the ground leg of the regulator as a means to increase the regulated voltage. Another good suggesion was to use a LM-317 and adjust it as needed. Other info: I found inexpensive 7806 devices with LOW shipping (via US Post) at Parts-Express.com, so I should have some arrive here in a few days. Again, thanks to all for the suggestions and help! Mark N8MH _____ Hello All, It appears that the 7806 voltage regulator in my Yaesu G-5500 control box has gone bad; the output is measuring more like 10.8 Volts (!). This explains why both position indicators were off by a factor of 2 (e.g., elevation meter showing 90 deg, array pointing 45; azimuth meter showing 180 deg, but array pointing 90 deg., and so on). Question---has anybody used a 7805 to replace the 7806 regulator in this control box? I don't have a 7806....so this brings the next question--anybody have a 7806 (or 2) that they want to sell?) Thanks, Mark L. Hammond [N8MH]

SSB Preamp
by Peter 16 Aug '08

16 Aug '08

HI, "The fault lies in thyself", was uttered many moons ago but that quote now applies to me! In summary I could not get my SSB 70cm preamp to work with my Icom 910; Jerry of SSB gave me terrific support to try get it working, and found it hard to believe that the relays engaged and it did not function. He said in 15 years not one was DOA, and said the only conclusion was that it was connected to the wrong antenna. I did the system checks that were suggested by this BB and still no joy. Convinced that the unit had a problem I sent the SSB Preamp back to Larry, no surprise it checked out fine; guess what the coax was put to the wrong antenna upon installation. I'm the "village idiot"! I want to thank all those that responded, this BB is a terrific asset to anyone interested in getting help with Satellite activity, thank you and my sincere apologies for taking up the bandwidth an so much of Jerry's valuable time. 73, Pete, WB2OQQ

SEEDS in CW Mode?
by Bruce Robertson 16 Aug '08

16 Aug '08

It seems that SEEDS is in CW mode. Around 16:05 today, nstead of the cheery chorus of children, I heard thumping on FM, so I switched over to CW. The doppler seemed way off, so I wasn't able to copy any code, but the signal disappeared at exactly the right time. Alternatively, it was another satellite that I don't have programmed into my SatPC32 right now, but in that case SEEDS' signal was unusually low. 73, Bruce VE9QRP

Re: DIY: Parabolic mirror
by James Whitfield 15 Aug '08

15 Aug '08

Finally. I was wondering if this thread would pass from the grousing and "It'll never work" stage into something more like "How can I take this idea and adapt it to something I want." The end product of the two videos was a curved mirror, presumeably intended to be a part of a solar energy collector. The material used was a reflective film, which needed to be mounted on a properly shaped and smoothed surface, which was made of fiberglass/resin. Its shape was determined by form, in this case made of concrete, which was cast in the concave end of a used water tank. Can this be applied to another project......Maybe with a little thought and a lot of adaptation: A few months ago, I had the idea to demonstrate PSK31 communications at a Boy Scout event, only I wasn't going to use radios. My idea was to use a speaker/microphone mounted at the focus of a paraboloid reflector to send the sound a few hundred yards to another similar setup. I didn't have the time to construct the project for the Scout event, largely because I would need to build a parabolic surface 30 to 60 inches in diameter. But I haven't dismissed the idea entirely. Some of you might be interested in a parabolic radio wave reflector. Buying one may be outside your budget, so you might consider trying to build one. The videos suggest a way to build a curved surface, that is common to the sound and radio projects suggested above. Parabololic would be the mathematically ideal shape. In practice, as was discussed in previous posting, the surface needs a smoothness better than a quarter wavelength at the frequency in use. The shape is often spheroid, the distinction and the actual choice of shape should be another discussion. The point being, it is possible to define the desired shape and the allowable errors. Would a fiberglass shell built up on a concrete form meet the shape and error requirements? Perhaps. For my sound project, the wavelengths under consideration start at about 4 inches and get longer. ( 3,000 Hz at 1,000 feet per second, and down to about 250 Hz, typical of PSK31 output from a sound card. I would get better results using 6KHz or higher frequency sound waves. ) I can be pretty confident that the shape and smoothness requirement could be met with the DIY manufacturing technique. Would it work for a radio reflector -- choose a frequency, calculate the shape and smoothness, then make your own judgement call. If you wanted to use it for an optical telescope, not a good idea. It was after all, originally designed for a solar cooker, shaped and smoothed to put the sun's rays on a cooking pot, not star images on film. What about the reflector material? For a sound reflector, I don't need shinny plastic to be added, the fiberglass would be reflective of sound by itself. Painting might help smooth the surface, particularly if I had to fill bubbles or sand down other flaws. For radio waves, I seriously doubt the plastic film would be adequate. You might be able to use aluminum foil or tape. Thinking differently, you might consider metal screen as the first layer of material in the construction of the paraboloid shape. Then add resin and layers of fiberglass to strengthen and set the shape. ( No. I have never tried it. I have no idea if it is worth trying. ) It may be possible to put a conductive coating on the shape, then electro-plate copper onto the surface in a thickness that will reflect radio waves. Maybe someone else has better ideas on how to make a radio reflective surface to be added to the curved surface. Substitute some materials. I briefly considered paper machet or a wood and stryofoam form instead of the concrete suggested in the video. The concrete form is probably more durable and stable, but it requires that you have a mold that you can pour it into. That means another chance for "copy errors". Might be well worth the trouble if you intend to make several. I also considered paper machet instead of fiberglass for the shell material. It would have been something that the Scouts could build. The problem is that it shrinks as it dries, so the shape would not be very precise. After doing some research on construction, I found out that they used to make boats and canoes out of paper and glue ( waterproofed with paint and varnish ). The end product was probably not as light or as durable as the wooden boats produced at the same time, but certainly less expensive. They had their niche. From that, I seriously considered paper/glue composite my primary choice for construction - again, mostly so that it could be constructed by Scouts with available, low hazard, materials. Does any of this have any relevance building a parabolic reflector that can be used in satellite communications? If it gives you ideas, or challenges you to find a better way.....More likely you will just shake you head murmuring about that crazy old geezer and his crack pot ideas. I tip my hat to those of you who are my elder, and wish health and long life to all. James n5gui
