Kenpro-Yaesu 5400 5600B question
by bpn518＠aol.com 01 Jul '09

01 Jul '09

Good day sat-guys: I have an old Kenpro G5400 without computer interface and a newer Yaesu G5600B control box. What are the differences in the motors between these 2 series other than the limit switches? In case of the control boxes, I see the G5400 has starter motor caps, but the G5600B control box doesn't. The old motors didn't work with the 5600B box until I added a starter cap to both the AZ and EL motor lines. I am planning to use the 5600B box with LVB tracker- any other issues? What do I need to do to use my old motors with the G5600B? Or, anyone have 5500 motors that they wish to sell? Any assistance would be appreciated. Thanks, Bennett ko2ok

AO-51 Telemetry
by Gould Smith 01 Jul '09

01 Jul '09

The AO-51 telemetry archive is up to date as of last night. AO-51 telemetry data is available in raw format, CSA (comma separated variable) format that has the channel data converted by the configuration equations and there are some Excel files (most with graphs). There are a number of Excel files with graphs for June 2009 as that was a very interesting month for AO-51 operation. The telemetry archive can be found at http://www.amsat.org/amsat/ftp/telemetry/ao51/ I encourage exploration of the data and any insights gleaned. 73, Gould, WA4SXM AO-51 Command Station

For sell...M2 NIB 436CP42UG Antenna
by R. Chastain 01 Jul '09

01 Jul '09

Hi all, I guess I better start off with saying the box is missing in action.:-) The antenna has never been built and all of the small parts, phasing harness, ECT... are still in the factory sealed bags. The reason the box is missing is because I unboxed it the day I got it and the grandkids decided the box would be a fun toy. Scratch one box. Other than the M2 box, the antenna is as mint as they get. Even the straps holding the elements and boom pieces have never been removed. I will sell for $300.00 plus shipping. Thanks, RoD KD0XX

Re: Help - no antennas allowed
by n0jy＠lavabit.com 01 Jul '09

01 Jul '09

Sorry for being kind of late to the party for this subject. John, I don't know if you are building or buying but in the case of the former my XYL and I are designing a house right now for an area which doesn't strictly prohibit antennas like I have now, but would likely not allow it. Working with the architect we have the plan for the attic space to be able to contain my current KLM 40el. (20x20) 70cm and Cushcraft 20el (10x10) 2m antennas as well as my 23cm VE3NPC type helix and 13cm K5GNA BBQ dish. It makes for a high roof, but many homes in Texas these days have steep roofs so the design actually looks normal from the outside. The basic idea is a 9 1/2 foot radius hemisphere that's 5 1/2 feet above the floor of the attic (5 1/2 feet being the height of the boom above the floor). It took some explaining to the architect how an az/el antenna setup works and looks, but he got the right idea. I can send you a .pdf of the roof/attic drawing if you are interested. The house is about 4500 sq. ft. area under roof in order to accomodate my antennas (although the size is a result of what we wanted for the floor plan, not the result of what was needed for the antennas). And, it was good to see Eric's link to DH5MK. It gave me a lot of relief to finally see an installation similar to what I am planning! I wasn't sure how satellite through a roof would work over the various bands, but it seems to me that any loss can easily be overcome by preamps and amplifiers in a space where you can hook up whatever you need without the worry of weather. 73, Jerry N0JY

Now this makes me wonder, When posting on this board to provoke stimulation about SATCOMMS; It appears that posts can be more stimulated over QSL cards or who's operating the latest in Spam Radio Du-lux than antennas or pre-amps or phasing harness' or Polarity Switching or the latest in GAS-FET performance etc;. OK,, I'll be more interested in that;... Now, Where's my QSL card from the ISS that I sent away for,,, now was that last year or early this year;? Maybe mines been held up by AMSAT -AUST or AMSATVK (cant figure out why??) I can't seem to remember when I sent away for it, maybe I've been concentrating on less important things like building projects to do with Amateur Radio instead of buying everything off the shelf, or doing totally nothing within an appointment which is becoming more apparent in Australia. Put up, Shut up or get out, you know who I'm commenting too!!! Frank VK5KV

Unused Sats
by Dave 01 Jul '09

01 Jul '09

This is an intriguing possibility and perplexes me somewhat they (AMSAT) hasn't mentioned it, or something similar. For instance, every launch has a ballast load. Why is it that the ballast cannot be replaced with a cubesat? Why aren't commercial sats required to have a amateur band transceiver installed, as mentioned here and elsewhere, to activate when the primary mission ceases? Public utility companies and regulated companies such as AT&T help us routinely. Of course the easy answer is 'no', but a thoughtful consideration from the people who deal with this on a daily basis might be more nuanced. It's not a technical issue, is it? Moreover, rigging a series of sats with a transmission system that switches on in the event of catastrophic failure or switching off of the main system offers the possibility of establishing a sat network capable of vast distance datacom at no expense to the primary carrier and of great benefit to the general public and science. Isn't it time we move to working on a deep space internet system that the commercial folks don't want to spend a lot of money on, and that we (ham folks) can help by proving-in the concept? Seems to me we can do this without a lot of expense but with the foresighted help of the commercial folks. Dave DM78qd // KA0SWT If it weren't for Philo T. Farnsworth, inventor of television, we'd still be eating frozen radio dinners.-- Johnny Carson +++++++++++++++++++++++++++++++++++++

Original 13 Colonies Special Event
by n3tl＠bellsouth.net 01 Jul '09

01 Jul '09

Hey everyone, As I type this (1304 UTC), the Special Event has begun! My thanks to all of the operators who've volunteered to help activate colonies on the satellites. Thanks, too, to everyone at AMSAT for the support it is providing, including a presence on the AMSAT-NA home page. That simply is wonderful, and very, very much appreciated. One last update - we've added Maryland! Bruce, WA3SWJ, will be activating that colony during the event with the special call sign WA3SWJ/K2F. That means we have 11 of the 13 original colonies active on the satellites from now through midnight EDT Saturday (0359 UTC on July 5). That is outstanding! Here, I intend to work CW quite a bit on the linear satellites (AO-7, FO-29 and VO-52), so listen for N3TL/K2G below the middle of those satellites' passbands. I'll try to work at least one pass of each satellite in SSB, but I hope we can get some CW ops on the air and in orbit! 73 to all from the Georgia Colony! Tim - N3TL/K2G

AO-27 Question
by Jim Jerzycke 28 Jun '09

28 Jun '09

Hi, everybody. Today at Field Day was the first time I tried to work AO-27, and succeeded. One thing I noticed, is that as the satellite came up over the horizon, I wasn't hearing anything until what sounded like a long data burst happened. Then I heard the sat come alive, with what sounded like people already in QSO. As the sat progressed, I heard a lot of operators, then the long data burst happened again, and it seemed like the sat went "dead" I know a bit about how it's scheduled (TOPR), but since this is the first time I was able to hear it well enough to actually consider it usable. What's the data burst? Is it part of the TOPR, or am I hearing something else? 73, Jim KQ6EA

/Hi Sebastian, I planning to work at 5W for now. I will use my 2 FT-817.... one for RX and the other one for TX.... both controlled by SatPC32. I bought 2 premamps RF switch at 25W maximum from Advanced Research. J-F VA2SS From/: Sebastian <w4as@xxxxxxxxxxxxx <mailto:[email protected]>>/ Date/: Sun, 28 Jun 2009 22:12:06 -0400 I'll add a thought here that I haven't seen anyone reply about. As everyone mentioned, definitely go with a preamp - but think for the future. How much transmitter output power do you have? If you have relatively low power, say 5 watts, you can get an inexpensive preamp. However, if you plan to use higher power in the future, perhaps for meteor scatter; that low power preamp may no longer be useful. Again, you've received several responses, but one thing hasn't been mentioned. What is your output power? If you have an HT with a couple of watts, that RG-8 may 'eat up' a lot of your power, especially if you are going to transmit on 440 Mhz. Without knowing how much power you have, and which birds you plan to use, it's difficult to give you a good answer. "you can't work 'em if you can't hear them"; also don't forget that you need to hear yourself FIRST. Work on hearing your downlink if possible before you start to call other stations. If you can't hear yourself, then post about it so we can help you out. I think it would be helpful if you told us which type(s) of rig(s) you will be using. When you find a fellow ham who has all the money that's necessary to build a perfect station, please let me know! 73 de W4AS Sebastian

Wow... many many answers !! Well, everybody seems to be agree that preamp are a "must", and the first thing to add in my setup. I bought, at a great price, 2 "second hand" and near perfect eggbeater antenna from a ham here in province of Quebec who would like to upgrade to a more serious setup. Ok now, I just ordered 2 preamps from Advanced Research... VHF and UHF. I will put them in an wheater proof enclosure near my eggbeater antennas..... the closer I can.... in an PVC enclosure... because I bought standard one. I received today from a friend of mine, a brand new 50 meters 1/2" heliax coil.... I will be able to change my 2 old coax runs with this. And finally, I will use my 2 FT-817 with SatPC32.... seems to work perfectly at this moment... the 2 rigs are controlled simultaniously RX & TX.... a great piece of software !! I hope I will be able to do a step further soon.... to have a contact !!! 73 J-F VA2SS Jean-François Ménard a écrit : > Hi, > > I would like to know if there is much difference using a preamp for > satellite receiving using a M2 Eggbeater antenna ? > > And also, is there much difference between a heliax 0.5" and a RG-8 > on a 50 feet cable run between the antenna and the radio ? > > I would really like to optimize my receiving quality but I also want > to know where to put all my effort first. > > I'm new and I cannot invest much money the first year. > > Thank to all for your advice. > > 73 > > --- > Jean-François Ménard > VA2SS > >

There's a TREMENDOUS difference with the preamp, mounted at the antenna. You will hear the satellites earlier, and stronger, with the preamp. Good coax is also good to have, but if you're on a budget, buy the preamp first. I tried many different things, but the preamp made the most improvement. 73, Jim KQ6EA --- On Sun, 6/28/09, Jean-François Ménard <va2ss(a)me.com> wrote: From: Jean-François Ménard <va2ss(a)me.com> Subject: [amsat-bb] Need advice : Eggbeater antenna, preamp, coax To: "AMSAT Mailing list" <amsat-bb(a)amsat.org> Date: Sunday, June 28, 2009, 1:16 PM Hi, I would like to know if there is much difference using a preamp for satellite receiving using a M2 Eggbeater antenna ?

Re: Advice for transponder ops
by Jim Jerzycke 28 Jun '09

I also noticed a lot of "warbling" on the AO-7 stations I heard. I'm assuming this is the "FM'ing" I've read about. I cranked my power down to about 10 Watts on the AO-7 passes I tried to work, and my downlink sounded "OK", but some guys had a very 'watery' sound. I also noticed a couple of sats where the downlink seemed to "drop out" after I heard some very LOUD stations on them. I don't think it was receive blockage causing me to lose the signal, but it was something I never heard before.

Velocity factor
by PE0SAT 28 Jun '09

28 Jun '09

Thanks for reading, Hi read the following and look at the image attached, after that, can you tell me if there is a velocity factor when calculating the 1/4 lambda distance between the horizontal and vertical antenna? The "Physical Method" following a different technique in order to avoid the use of coaxial piece for the necessary 90° phase's difference. Here the "Phase Difference" has been achieved by "shifting" (moving) each element of the 2nd (Horizontal) antenna exactly one Quarter-Wavelength (ë/4) forward in space, vis-a-vis to each element of 1st (Vertical) antenna onto the common Boom. Thanks, Jan -- With regards PE0SAT Internet web-page http://www.ham.vgnet.nl/

Original 13 Colonies Special Event Update - K2T
by claryco＠aol.com 28 Jun '09

28 Jun '09

Instead of signing K2J as initially planned, I was able to get "K2T" ("T" since North Carolina is the "Tarheel" State) assigned to me at the last minute for the 1-4 July time frame. K2J will still be on the air from NC, at least on HF, and I'll be QRV on both HF as well as the sats. I'll be on the FM birds at the least; the linear sats will be used as well if I can get my Acer netbook to use SatPC32 to talk to my 897 and?adjust the freqs for Doppler. Contacts with either K2J or K2T will count for North Carolina toward the certificate offered for the event. Nine of the 13 colonial states will have sat stations on during the event. We're still looking for ops for Connecticut, Delaware, Maryland, and Pennsylvania. Pse note that the special event runs the calendar days of 1-4 July; per the event web site, it officially runs out at 05/0400Z July. Finally, for?any sat op who is a county hunter, I'll be running North Carolina counties on both CW and SSB on 20, 30, and 40 meters as K2T throughout the event period and then using my regular call afterward on the way home to Florida. Spots of my HF county hunting operation will be available at http://ch.w6rk.com/?and will include the county that I'm in at the spot time shown. Although the grid square is not indicated on this web site, it shouldn't be difficult to identify since the county I'm in is shown. 73, Jim, ND9M / VQ9JC / K2T

Advice for transponder ops
by Andrew Glasbrenner 28 Jun '09

28 Jun '09

I took this screen grab of this morning's eastern FO-29 pass, and what it shows is in my opinion very illustrative of a problem that is getting worse even on days other than Field Day. http://i139.photobucket.com/albums/q305/glasbrenner/radio/FO-29FDanotated.j… Spread out! There is no good reason that we should have a dozen operators fighting over the center 15 kHz of a 100 kHz wide transponder. Remember the gentlemen's agreement is the lower third is for CW, middle 1/3 is for mixed ops, and the upper 1/3 is for SSB. There is nothing magic about the Doppler shift at the very center of the passband that simple addition and subtraction can't duplicate elsewhere. Just my opinion, and please take it constructively. 73, Drew KO4MA

4C50C via satellite, through 31 August 2009
by Patrick STODDARD (WD9EWK/VA7EWK) 27 Jun '09

27 Jun '09

Hi! Omar XE1AO, a regular satellite operator from central Mexico, e-mailed me news of a special callsign that will be showing up on the satellites between now and 31 August 2009. The call, 4C50C ("Four Charlie Fifty Charlie"), is part of the "Trabaja Todo Colima" (Work All Colima) special event currently taking place in the central Mexican state of Colima. This event is commemorating the 50th anniversary of the creation of the J. Roberto Levy radio club in that state. During the months of June, July, and August, stations from all over Colima have been on HF and the satellites, trying to put all 10 Colima "municipios" (municipalities, similar to counties in the USA) on the air. On HF, the special call XE50C has been used from different parts of Colima. Now, four hams (XE1AO, XE1ATZ, XE1AY, and XE1J) have been authorized by the Mexican telecommunications regulator CoFeTel to use 4C50C on the satellites as part of this event. Initially, XE1AO will attempt to put 4C50C on AO-51's evening passes along with VO-52 and FO-29 evening passes. Omar and the other 3 hams hope to expand the use of 4C50C onto SO-50 and AO-27, plus look at passes at other times of the day during this period. For hams outside Mexico, XE1J is the QSL manager for these special calls. The Mexican QSL bureau will take care of QSL requests from XE hams. Along with the QSL cards, there will be a certificate available to stations that work stations in at least 7 of the 10 Colima municipalities and also accumulate at least 74 points based on the location of the stations worked in Colima. Additional points are available for working certain stations like XE50C and 4C50C. More information (in Spanish) is available at: http://arco.sat-xe.org/XE50C/XE50C.html and also: http://arco.sat-xe.org/4C50C/4C50C.html For now, the 4C50C page is a mirror of the XE50C page. It will be updated shortly, with new information related to the 4C50C call. Good luck, and 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

Re; Circular switching
by Frank Woolfe 26 Jun '09

26 Jun '09

Hi Jan PE0SAT, my emails are not getting through to you so I'll post here, I have had some success so far, I've made up two lengths of RG213 with 1/4 wave lengths of 75ohm cable on each end. These are to run from the coax relay to the 145mhz Yagi's as the ARRL drawing suggests. N type connectors are used on each end of these cables. I've tested this as a phasing harness and achieved around 30dB return loss that's with the 75ohm transformer ends in a T piece and 50ohm loads on the end of each cable. This was tested on my HP8920 using a 50Mhz to 1000Mhz Narda coupler and am happy with the results, so the phasing harness as it is, is centered on 145mhz with a VSWR of 1.06:1. Next is the delay line, this has got to be an impedance of between 104 to 110ohms, as the antennas are between 52 to 55ohms now this is going to be hit and miss, as you can't get 105ohm coax. However, you can get 93ohm and what I'm thinking is to remove the center conductor of the coax and replace it with a smaller diameter conductor this should raise the impedance of the coax hopefully to around 105-110 ohms, thus achieving the required impedance of the delay line which is called for in that circuit. The 93 ohms is just too low and I've found with my testing so far it's better to be on the high side of impedance than the low. The 93 ohms seems to look like near enough to 75ohms and acts like another transformer section. So I'll continue on and keep you in the loop on success or failure. Thanks for your mail and Best 73's Frank VK5KV...

ISS Field Day information
by n3tl＠bellsouth.net 26 Jun '09

26 Jun '09

Hey everyone, The president of the Athens Amateur Radio Club just posted this to our local reflector. I'm confident it came from ARRL. Possible International Space Station Contacts for Field Day 2009 This Field Day, astronauts aboard the International Space Station plan on making contacts -- using club call signs as well as their personal call signs -- with amateurs on the ground (as time permits). Will you be one of the lucky ones who get an ISS QSO this Field Day? According to NASA ISS Ham Radio Project Engineer Kenneth Ransom, N5VHO, there is a good possibility that groups participating in ARRL Field Day may be able to make a contact with one of the astronauts aboard the International Space Station (ISS). "Some of the crew members of the International Space Station plan to make contacts with operators on the ground during Field Day operations as time permits" Ransom said. "Since the ISS now has a multinational crew representing all five space agencies, the possible club call signs to be heard are RS0ISS, NA1SS and OR4ISS. The crew could also elect to use their personal calls, as well. In either case, they will be signing 1A (Alfa) ISS after the call sign." ARRL Field Day Manager Dan Henderson, N1ND, said he is excited about the potential ISS participation: "In my 11 years heading up Field Day for the ARRL, I can think of nothing that causes more excitement around a Field Day site than the group completing a contact with the ISS. It is almost electrifying!" But Henderson exercised caution, saying that there is always the possibility that circumstances on board the ISS will change and the astronauts will not be able to operate during Field Day times. "We are pleased to have their commitment to attempt it again this year," he said. "There is an ARISS contact on the schedule for Saturday morning before Field Day officially begins, so there is a good chance that on later passes, amateurs may get a chance to experience a unique thrill." Ransom reminded US amateurs that talking to the crew on the ISS does not qualify for satellite bonus points, "but it is anticipated that the crew will have the crossband repeater active (437.80 up/145.80 down, no CTCSS), so any contact you make with another ground station using his repeater can count for the bonus. Of course, working an astronaut on Field Day has its own reward." Remember that the ISS circles the Earth about once every 90minutes. As the Earth turns, the orbit of the ISS does not always give US amateurs a good path every orbit. "Some passes will favor some parts of the country while passes will favor others," Henderson said. "There will be passes where the US itself may not be in the 'footprint' of the ISS." Henderson suggested that Field Day groups trying to contact the ISS visit the AMSAT Online Satellite Pass Predictions Web site. To use the Pass Prediction tool, first, select the ISS in the "Show Predictions for" box. Next, input both your site's latitude and longitude -- or input your grid square -- and the click the "Predict" button. From the predicted information you receive back, you will want to look for orbits that occur within the Field Day operating time beginning at 1800 UTC on Saturday, June 27 for the following 24-27 hours, depending on your group's operating window. "You want to find a pass that has the highest maximum elevation," Henderson said. "For example, the best Field Day pass at W1AW is going to be at 62 degrees of elevation beginning at 11:44:30 UTC on Sunday, June 28 that will last for approximately nine to 10 minutes (AOS to LOS). Don't be discouraged if you don't have a lot of passes that have outstanding elevations or durations. And remember, if you don't complete a contact with the ISS, you can use the same prediction tool to see what other amateur satellites you might try to contact." Best of luck to all, Tim - N3TL

G-5500 rotor motor intermittent
by Michael Hatzakis Jr MD 24 Jun '09

24 Jun '09

Andrew and group, Read this post and others about the 5500, and I am trying to figure out what do with my rotor or my controller. My rotor has become more and more intermittent over time, so I opened up my cables and put molex connectors in line so I can debug. I started with impedance of the rotor. My Elevation is working now and my rotation is not. I pulled out the schematic and see that the rotor motor is on 4-5-6 with the common on 6 each and the up/down or left/right on 4-5. I measured the impedance of 4 & 5 against 6, and the Ele was near 2-3 ohms and the Ele was open. I am wondering if this is an intermittent internal limit switch? Taking my rotor apart is a huge deal, so I want to be sure I am looking at this situation correctly and what else should I be looking for or measuring?

I had my G-500 a month before the motor went out and had to send it to Yaesu. Everything was balance as well. What I think happened is one of the buttons on the control box got stuck in one direction and caused the motor to burn up. What I did was change the fuse that Yaesu uses from a 2 amp AGC to a 1 amp slow blow fuse. Just in case this happens again, at least the fuse will blow before causing the motor to go out. 73 de Angelo --------------------------------------------------------- If you don't ask, you will never know!! >From: Andrew Glasbrenner <glasbrenner(a)mindspring.com> >Reply-To: Andrew Glasbrenner <glasbrenner(a)mindspring.com> >To: amsat-bb(a)amsat.org >Subject: [amsat-bb] G-5500 rotor motor woes >Date: Mon, 28 Mar 2005 09:20:31 -0500 (GMT-05:00) > >About 3 weeks ago my azimuth rotor motor bit the dust.

Another Field Day Call
by DeYoung James 24 Jun '09

24 Jun '09

Greetings, I will be the satellite station (VHF/UHF terrestrial too) for the Alexandria Radio Club (W4HFH) operating in FM and SSB modes only. It will be interesting this year since there is a big high-tension power line and substation in one quadrant, buildings in two other quadrants and high steel overpasses from I-95 in the other quadrant. I wonder if I'll be able to hear anyone? Perhaps I'll only hear my own reflected signal or maybe I can resonant all the metal around and talk down to the horizon! Nothing like a little RF anarchy while operating in harsh conditions I say! What did you say your call sign was? Which station is going to be near the center of the passband? Hi, hi!!! Jim, N8OQ

Special Event operation coming to the satellites!
by n3tl＠bellsouth.net 24 Jun '09

24 Jun '09

Hey everyone, This time next week, at least nine of the Original 13 Colonies will be active on the amateur satellites as part of a special event organized by Ken, KU2US, in New York. Here is the Web site announcing the event, and the certificate available: http://home.comcast.net/~dzabawa/ThirteenColonies.htm You’ll also find updates on Ken’s QRZ.com page – look up KU2US. When I saw an email about this special event, I contacted Ken and asked if he’d consider including satellite operations in the event. He responded with an enthusiastic yes – then told me to get everything organized as quick as I could because we were running out of time! I’m glad to do it because this should be a fun event for us on the satellites. As I write this, we have commitments from stations in nine of the original 13 colonies, and they will be using the call signs for each that are listed on the special events page. For example, I’ll be operating as K2G daily during the special event. I intend to work at least one pass of every satellite as K2G, every day. Listed alphabetically by Colony, here are the stations that have confirmed to date. The calls they will use are in parentheses: Georgia – Tim, N3TL (K2G) Massachusetts – Dave, KB1PVH (K2H) New Hampshire – Rik, N1XED (K2K) New Jersey – Marc, W4MPS (K2I) New York – Peter, WB2OQQ (K2A) North Carolina – Jim, ND9M (K2J) Rhode Island – Fletch, N1RCN (K2C) South Carolina – Art, K4YYL (K2L) Virginia – Steve, NL7VX (K2B) As of now, there are four of the original 13 colonies NOT scheduled to be active on the satellites: Connecticut Delaware Maryland Pennsylvania Can anyone help with any of them? The process is simple: 1 – Please email me off the BB to let me know of your interest. 2 – You can work as many or as few satellite passes as you like during the special event. It’s supposed to be fun, not work! 3 – After the event, email your log(s) to KU2US, who will handle the certificates. I’ll provide more information after hearing from anyone who wants to activate one of the four remaining colonies. Everyone is welcome and encouraged to work one or more of us on passes from July 1 through July 5. You only need to work one station to get the certificate, but the more the merrier! 73 to all, Tim – N3TL

Addtionly, according the ARRL FD rules, DX stations should send their operating class and "DX". The operating class for your typical home station would be "1D", so the exchange would be "1D DX".

Phase shift keying question
by n8bbq＠roadrunner.com 23 Jun '09

23 Jun '09

Andy, Grants explanation of I/Q modulation is excellent. Perhaps your conversation involved using complex sampling (I/Q) to double the bandwidth compared to simple sampling. The usable bandwidth is limited to about one half the sampling frequency (google NYQUIST). When looking at faster convertors you reach a point where doubling the conversion rate more than doubles the cost, or a convertor that fast may not exist. By using two simultaneous convertors, sampling the I and Q signals, the usable bandwidth is doubled. If two channels are available, there is a way to double the data rate without involving the I/Q signals. Of course I am speculating about the nature of your conversation, so I may be way off. Hope this helps. '73 de Ed N8BBQ

AO-51 adjustments
by Gould Smith 22 Jun '09

22 Jun '09

I am working with the satellite to get the Field Day configuration operational long term.. I turned TXB back on during the 1300Z pass. During this pass I adjusted the TX levels to TXA 240 mW and TXB 290 mW. These are lower power levels than I have ever used before, but necessary to get the satellite through the 16+ minute eclipses each orbit. The SQRX receiver uses about 110 mA that must be subtracted from the total TX power used. I think I am close and expect to get the correct settings over the next 24 hours. It is also necessary to change the L/U analog operation to digital over the eastern US in order to download the telemetry to see how the satellite is performing over multiple orbits. 73, Gould, WA4SXM AO-51 Command Station

Phase shift keying question
by Grant Hodgson 22 Jun '09

22 Jun '09

Andy I/Q modulators don't work that way, no free lunch and all that. In newbie terms, an I/Q modulator can be thought of as a special mixer that can modulate a carrier signal with an arbitrary modulation format - i.e. any type of modulation you want - literally. An I/Q modulator has a Local Oscillator input (carrier), an I input and a Q input, and an RF output. The modulation signal (FM, CW, AM, SSB, FSK, PSK or whatever) is applied to both the I and Q inputs, which in turn modulate the LO signal to produce the output signal. The type of modulation is determined by the phase relationship between the I and Q inputs. Couple of simple examples - lets say the modulation signal is a 1kHz sine wave, and we have an LO signal of 144.100MHz. If both I and Q inputs are fed with this signal - in phase - then the output of the I/Q modulator will be AM, at 144.100MHz, modulated at 1kHz - you will hear a 1kHz tone on an AM receiver. If the I and Q inputs are fed 90 degrees out of phase with the same 1kHz tone, then the output of the modulator will be either LSB or USB depending on whether the I signal leads or lags the Q signal. If the receiver is set to 144.100 kHz you will hear a 1kHz tone when set to the appropriate sideband. With slightly more complex phase relationships between the I and Q signals it is possible to generate any type of modulation you want, and from a receiver's point of view you will not know how the modulation was generated. But you can't feed different modulation channels into the I and Q inputs - the output would be a complex mixture of the two which would be un- decipharable. You could try Googling 'IQ modulation' for more information, although some of the explanations are aimed at professional engineers with good maths skills. HTH Grant G8UBN Could anyone please explain, in newbie terms, if it is possible to split a telemetry data stream from a satellite OBC into two data streams, sent simultaneously on two nbfm channels, each PSK with the phase difference between them? I have in mind a conversation which I don't fully understand, about these being the I and Q components, and this offering a doubling of the data rate compared with using one nbfm channel.

Hello I am fowarding this to the AMSAT-BB. I am sure it will be of interest to some of us. I asked Loren what down converter he is using, DSP software etc. If any of you have any information as to how to do this I would like to know. I do not think the transystem 3731aa DC will work down to 2271. 73 Bob W7LRD ----- Forwarded Message ----- From: "Loren Moline WA7SKT" <lmoline(a)hotmail.com> To: pnwvhfs(a)googlegroups.com Sent: Saturday, June 20, 2009 6:29:10 PM GMT -08:00 US/Canada Pacific Subject: [PNWVHFS] LRO Hello. For those who have S-Band receive capability the Lunar Recon. Orbiter can be heard at 2271.190Mhz+/- doppler. It is a carrier and best found with a DSP audio spectrum program or an SDR.

June 21, 2009 To All RADIO AMATEURS BID: $ANS-172.2 AMSAT's Satellite Field Day is held concurrently with the annual ARRL Field Day emergency preparedness exercise. This year the event will take place between 1800 UTC on Saturday June 27, 2009 through 2100 UTC on Sunday June 28, 2009. AMSAT encourages stations to prepare for operations on all of the satellite modes - analog, FM, and digital. The congestion on FM LEO satellites has become so intense based on experience in prior years that we request to limit your use to one-QSO-per-FM-satellite. The ARRL rules only allow one contact per FM satellite to count. AMSAT Field Day rules allow one contact per FM repeater to count. This includes the International Space Station, if operational. AO-51 will be configured to support Field Day operations. The Field Day configuration on AO-51 begins on June 21 to allow stations to test their equipment and antennas at home prior to the event. The satellite will remain in this mode through June 28. AO-51 June 21 - June 28 Field Day Configuration FM Repeater, V/U Uplink: 145.920 Mhz FM Downlink: 435.300 Mhz FM FM Repeater, L/U (Subject to interuption for telemetry collection) Uplink: 1268.700 Mhz FM Downlink: 435.150 Mhz FM The full text of the AMSAT Satellite Field Day Rules can be found on-line at: http://www.amsat.org/amsat-new/awards/amsatfd.php The Satellite Summary Sheet can be found on this web page also. This format should be used for submission of the AMSAT Field Day competition and be received by KK5DO (email or postal mail) by 11:59 P.M. CDT, Monday, July 13, 2009. The preferred method for submitting your log is via e-mail to kk5do(a)amsat.org or kk5do(a)arrl.net. You may also use the postal service but give plenty of time for your results to arrive by the submission date. Add photographs or other interesting information so that can be used an article for the Journal.

Re: Field day and FO29
by Jim Jerzycke 20 Jun '09

20 Jun '09

It appears to be in its "normal" mode as Drew said. I was just listening to it about 2130 PDST, and there was quite a bit of activity. Unfortunately my own uplink is clobbering my downlink and I didn't have any success in making any contacts. I'm going to try the "duplexer trick" Sunday morning to see if it helps with the desense problems I'm having. Using two M2 eggbeaters with SSB USA preamps, and they're only about 8 feet apart. 73, Jim KQ6EA --- On Sat, 6/20/09, Andrew Glasbrenner <glasbrenner(a)mindspring.com> wrote: From: Andrew Glasbrenner <glasbrenner(a)mindspring.com> Subject: [amsat-bb] Re: Field day and FO29 To: kc6uqh(a)cox.net, "AMSAT-BB" <amsat-bb(a)amsat.org> Date: Saturday, June 20, 2009, 8:31 PM I believe FO-29 is operating continuously in Mode V/u analog at present. 73, Drew KO4MA ----- Original Message ----- From: "Art McBride" <kc6uqh(a)cox.net> To: "AMSAT-BB" <amsat-bb(a)amsat.org> Sent: Saturday, June 20, 2009 11:00 PM Subject: [amsat-bb] Field day and FO29 >I need some help with the schedule for FO-29 The current listing schedule > begins with July 1, And I need the schedule for June 27th 18:00 UTC to > June > 28th 18:00 UTC. > > > > Can anyone help me with this? > > Thanks, > > Art > > _______________________________________________ > Sent via AMSAT-BB(a)amsat.org.

I ordered the voltage pots from Yaesu on Monday 6/15 and got them today 6/19. Excellent shipping via Priority mail from California. I installed the Elevation pot this evening and the rotor is fat and happy again as am I. Yes fat and happy. Kodoos to Yaesu for the fine service. I wont be in town to operate K4CQ this year but the club will be able to run automatic control now. I will try to make some contacts from Holden Beach N.C. portable. Should be great fun. 73's << John -- N4QWF Amateur Radio Operator AO-7,AO-27,FO-29,SO-50,AO-51,VO-52,ISS Email N4QWF(a)AMSAT.ORG Echolink nodes #110903 -L #388463 http://home.comcast.net/~n4qwf/site/ Formerly KC4AHW VK3FEZ Amsat Member #27845 DXCC #33,478 VUCC SAT #135 WAS SAT #296 51 on AO-51 #13 LON -79.256 LAT 37.459 Grid FM07il >From the Foothills of the Blueridge *Life should not be a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming - "WOW, What a ride!"

Hi all, Please do not take this too serious. Right now I see a report on: http://oscar.dcarr.org saying that the crew is active on AO-7 in mode-A ? In my head I see small green men/women manning AO-7 :-) I just wanted to remind you about the possibility to report on that page.

Thanks - attic Antennas
by john heath 19 Jun '09

19 Jun '09

Thanks to everyone who replied. It seems that small yagis and quagis are OK in roof spaces provided that the liner underneath the roof tiles is not metalised. Contrary to my expectations, rain and snow on the roof doesn't cause problems. DH5MK has some nice pictures of his attic antenna installation on his web site. 73 John G7HIA

Hi all, Just a kind note of thanks for the many replies, both direct and on the website, in regards to operational Satellites. Often when a person is away from the aspect of the hobby awhile, it takes a bit to get your head around whats active and operational. I have printed out and tabulated what is available and where. The AMSAT - NA site for orbit prediction is invaluable and priceless.. Thanks again, 73 - Steve ZL1TPH
