W3XO's book
by na2x＠yahoo.com 08 Jun '10

08 Jun '10

I just received the recently released W3XO book ""AMSAT The First Forty Years" (available from the AMSAT store). Man, what a great book! As some one who has been involved with AMSAT from the early 1970's, Bill's description of the AMSAT activities through all these years was a true pleasure to read about. I'm sure even relative new-comers would enjoy reading it too. Thanks go out, of course, to Bill, W3XO for putting together this fine book, and all the contributions made to it by others, and especially to AMSAT for making it available to all of us.

And I heard in a presentation at the Cape some years ago that "We are so sure the solid rockets will ignite that we send the command to blow the hold down bolts before we send the solid rocket ignition command". Also I heard from somebody that the fractured hold down bolts are presented to the shuttle crew members as souvenirs after they return to Earth.

There is a pattern to this sort of spam/infection: 1. It ALWAYS comes from a webmail capable address (I have seen Yahoo, Gmail and Hotmail accounts infected). 2. It always features a single line with a URL, maybe with one line of generic text "Hey, look at this" or similar. How I discovered it was the account owner's PC being infected was that I posted an advisory message in the group that was getting spam, and suggesting everyone check their PC for malware. The account owner (that the spam claimed to come from) came forward and described what happened, and that they had fixed their system, once made aware of the problem. Subsequent instances of this type of spam have revealed a similar pattern. This was first sighted a few months ago. Anyway, hope this helps people affected by this sort of problem to find and remove the offending malware. 73 de VK3JED / VK3IRL http://vkradio.com

FIELD DAY SCORING
by Peter Portanova 07 Jun '10

07 Jun '10

Hello, I was in contact with the ARRL, after I read 7.3.7. and 7.3.7.1. in the Field Day Rules. I mentioned to the League that I would like them to point out where in those rules it would prohibit scoring the same call on multiple Linear Satellites. They listened to my point's and agreed that even though the rules refer to satellite contacts as a separate "band" there is nothing in those rules that prohibit the aforementioned scoring. In conclusion Field Day and the AMSAT scoring are now in agreement, have fun. 73's Pete WB2OQQ www.massapequanyweather.com

I'll offer it here first. I have a Yaesu G-5400B rotor and controller for sale. It took some lightning damage to the controller but it has been repaired and works well. It is several years old and I am not the original owner. I will also throw in a Fox-Delta ST1. The ST1 is brand new - I still have the raw parts for assembling the cable that interfaces to the rotor controller. The rotor, controller, and ST1 for $300 firm. I also have the following antennas that I will sell locally (Tuscaloosa, AL) or will travel up to 50 miles: KLM 22-element 2m CP antenna - $100 firm Homebrew 44-element 70cm CP antenna - $100 firm I also have a couple of preamps - both Icom, one for 2m, one for 70cm that I could be talked into selling and an eight foot FG crossboom. All of this equipment is still mounted on a short tower, but can be removed easily. I can provide pictures if needed. Thanks for the BW. 73, Joel, W4JBB -- Joel Black jbblack(at)charter.net

Re HELIX REFLECTOR?
by Clare Fowler 06 Jun '10

06 Jun '10

To add to the discussion the July/Aug 2007 Amsat Journal has an article covering some gain comparisonmeasurements I made between four 13 turn (2.88 wavelengths) 13cm antennas with different square solid aluminum reflectors. The sizes were 0.56 wavelengths, 0.84 wavelengths, 1.0 wavelength and 1.4 wavelengths. There was no difference between the 0.84, 1.0 and 1.4 wavelengths but the antenna with the0.56 wavelength reflector had 1.5 db less gain. However for my 70cm helix antennas I followed the Satellite Handbook minimum size of 0.6 wavelengthsor slightly over 16 inches. I used 1/2 inch hardware cloth mesh to keep the weight and windloading down. These antennas have performed well however it appears that they would be a bit better with a somewhat larger reflector. A brief description and picture of the 70 cm reflector is in the November/December 2005 Amsat Journal article on The Development of a Quarter Wave Match for helical antennas.

WD9EWK on the move tomorrow to DM56
by Patrick STODDARD 06 Jun '10

06 Jun '10

Hi! Thanks to all the stations that worked me today, at the White Mountain Hamfest in Show Low and later in the day at DM44xj/DM54aj north of Show Low. WD9EWK logged 41 QSOs at the hamfest (including an amazing 12 QSOs on one AO7 pass around 1400 UTC!), followed by 47 more at the grid boundary. I hope to be up at DM56 Sunday morning for the 1620 UTC SO50 pass. I may be able to park on the DM55/DM56 line, but the primary goal for the day is DM56. I'll work passes on SO50, VO52, HO68, AO27, plus an AO51 pass just before 2300 UTC. Tomorrow will be a busy driving day - about 3 hours from here up to DM56, then 5 hours or so from DM56 back home. With the long drive home, I can't stay in DM56 for the passes after 2300 UTC nor do I plan to stop for any passes that I could work in the evening. I hope to work a bunch of you tomorrow from one of the rarely-heard grids in Arizona. 73! Patrick WD9EWK/VA7EWK - Pinetop-Lakeside, Arizona http://www.wd9ewk.net/

The Helix is made with a non annealed wiredrawn aluminum rod 8 mm in diameter and the boom is made with a very hard plastic pipe 42 mm outside diameter and 31 mm inside diameter originally used for hight pressure oil ducts. Following "ANTENNAS" from John Kraus the lenght of a turn has been made 1 wavelenght long into free space and the pitch angle between turns is about 13.8 degrees while the calculated half-power beam width is about 28 degrees. The matching system between the 150 ohm impedance at the feed point and a 50 ohm coax cable is made using a 1/4 electrical wavelenght impedance transformer with Zo = 86 ohm made with two coaxial tubing. For better performance and not to distort the pattern the antenna is fastened to the rear of reflector and the weight is balanced with a counterweight made with few lead disks. The picture of the above 15 turns helix antenna is visible at i8CVS in QRZ.com I have built two Helix Antennas the first one is a 10 turns with 0.67 wavelenght round reflector used beginning from OSCAR-7 to actually FO-29 and HO-68 and it works very well. The second one is a 15 turns helix with a 1 wavelenght in diameter round reflector and it was used for the uplink from OSCAR-10 to AO40 as can be seen at i8CVS in QRZ.com but unfortunately I cannot use it for LEO satellites because the AZ/EL mount is slow because it was designed for HEO satellites and this is why I pull for P3E ! If someone is interested to built the above antenna for 10 or 15 turns I can send a zipped file with all the electrical and mechanical sized drawings of it. Best 73" de i8CVS Domenico

Hi! This has been a good hamfest here in Show Low AZ. The morning started with 12 QSOs on AO7 around 1400 UTC! More on VO52 and SO50 later. Thanks to K8YSE and KD8CAO in Michigan for the QSOs, as well as N5AFV operating as KK5W in Texas. I will be on SO50 @ 1913 UTC followed by AO27 @ 1937 UTC to wrap up the hamfest demos. Thanks to WA8SME, N5AFV as KK5W, and AA5CK for talking with a Boy Scout that stopped by during the 1730 UTC SO50 pass! Several Scouts were able to satisfy several requirements toward th Radio Merit Badge, including the Scout who was on the mic. My first pass from DM54 (or possibly the DM44/DM54 boundary) will be a shallow AO7 pass at 2256 UTC. Hope to put more in the log then, to go with 33 QSOs wlready logged at the hamfest with two passes remaining. 73! Patrick WD9EWK/VA7EWK - Show Low, Arizona http://www.wd9ewk.net/

mmsstv usb ptt under wine
by Phil 05 Jun '10

05 Jun '10

Thank you for reading this. Not long ago I remember reading, on this list, about someone running mmsstv under wine. I've had receive only capability for sometime but after recently receiving good sstv from Seeds my interest in transmitting sstv has been reawakened. I have the extfsk dll installed in the same directory as mmsstv and its dialogue box opens to show that the ptt is on during transmit, however, the transmitter is not keyed. The port option in mmsstv is set to extfsk. The extfsk dialogue box has a status indicator the reads "Status:NG". This possibly means "no good". The status reads the same under Windows, so the problem may not be specific to Linux and wine. By the way, the rts line does key the transmitter while using native linux applications. -- Regards, Phil

I hope to hear K8YSE and KD8CAO at their hamfest in Michigan along with N2SPI at the Rochester NY hamfest and KK5W operated by N5AFV in Texas. Lots of activity tomorrow morning. After the hamfest, I will find someplace in DM54 for passes in the afternoon and evening. I have already tried to find a spot on the DM44/DM54 grid boundary. Trees and "No Parking" signs have ruled out some places I've already surveyed this evening. I found a spot north of Show Low that might work. I may be able to get on the AO-27 pass at 2118-2125 UTC from DM54 or possibly DM44/DM54. After that, I plan on attempting the following passes from somewhere in DM54 or on the DM44/DM54 boundary: 2256-2311 UTC on AO-7 SSB 2315-2329 UTC on AO-51 FM I have 3 passes that overlap in the 0040-0110 UTC period: 0043-0105 UTC on AO-7 SSB 0053-0107 UTC on FO-29 SSB 0054-0108 UTC on AO-51 FM I am leaning to working one of the SSB passes, probably AO-7 since it is the longest of the 3 passes. I might work the first part of the AO-7 pass, and then switch to AO-51 for the west-coast operators that may be looking for DM54. Please e-mail me if you are in the western US or Canada, and would like to try for a QSO on that AO-51 pass. After that, SO-50 comes by at 0206-0219 UTC. Then FO-29 and AO-7 pass by around 0237-0257 UTC. I'll probably start on AO-7, if I am still outside working the radio at that hour (approaching 2000 local). I don't want to stay out too late tomorrow night, since Sunday morning will start very early, for the 3-hour drive up to DM56 in time for mid-morning passes. As with my other road trips and hamfest demonstrations, I will be happy to QSL all contacts made with WD9EWK from the hamfest and wherever I end up in DM54 tomorrow. Just e-mail me with the QSO details; if you're in the log, I'll send out a card. 73! Patrick WD9EWK/VA7EWK - Pinetop-Lakeside, Arizona http://www.wd9ewk.net/

Re: Helix Reflector

Ed - KL7UW, WD2XSH/45 said: "You might be interested in the Helical Beam that Mike Cook designed in 1996 for reception of the Mars Global Surveyor (MGS). He used a 10.66 inch diameter loop Reflector. " I have built two 70 cm helix antennas using the loop reflector. The first one was an exact copy of AF9Y's at 11 turns. My first helix build. The second is an 18 turn also with the loop reflector but uses aluminum wire for the helix and the 10.66 in. loop reflector is 1/4 inch copper tubing. I'm going to remove it soon and change to a screen reflector to try out Claire's (VE3NPC) matching system. I'm working up an article on helix building and what I've been able to put together is that the reflector can be .6 to 1.1 wavelength. The ARRL Satellite Experimenters Handbook specifies .6 wavelength in their chart. GL Mike (K9QHO)

Another roadtrip planned
by John Neeley 04 Jun '10

04 Jun '10

Starting June 9th thru the 30th, we'll be on another vacation roadtrip, and like last year, will be taking the FT-60R and Elk yagi along for working the FM satellites at various stops. The only planned stops are in Yellowstone NP, Cody, WY and Mt Rushmore in SD, otherwise it is driving to other spots that look interesting. Possible other states to visit are ND, MT, ID, WA and OR on the return loop, but that isnt set in stone. There is a possibllity that we'll make a trek into Nebraska, so I can pick up my Gulf Alpha's that are ready, but not sure yet. More than likely I will be on passes early AM or sunrise and early PM or dusk. Hopefully I will be in some grids that are needed by some, and if so, just send me a QSL card (no SASE required) or email and I'll return a card. 73 de John W6ZKH DM06

Space-X to launch Falcon-9 tomorrow
by G0MRF＠aol.com 03 Jun '10

03 Jun '10

Hi all. This seems to have slipped below the amsat radar. Good luck Elon..... Friday 4 June 2010 Launch Window Opens: 11:00 AM Eastern / 8:00 AM Pacific / 1500 UTC Launch window lasts 4 hours. SpaceX has also reserved a second launch day on Saturday 5 June, with the same hours. As always, weather will play a significant role in our overall launch schedule. The weather experts at the Cape are giving us a 40% chance of “no go” conditions for both days of our window, citing the potential for cumulus clouds and anvil clouds from thunderstorms. If the weather cooperates, SpaceX will provide a live webcast of the launch events, presently scheduled to begin 20 minutes prior to the opening of the launch window. Click _here_ (http://www.spacex.com/webcast.php) to visit our webcast page which will also be accessible from our home page the day of launch.

g-5500 EL help
by Michae J. Wolthuis 03 Jun '10

03 Jun '10

Since my previously reported issues of intermittent Elevation control of my g-5500 where it would work and stop based on heat of the day it has now stopped completely and will no longer raise at all. Can someone point me down the correct paths to start testing where my problems are and if I need to send the controller or actual EL rotor into Yaesu for repair? Is there a good trouble shooting document somewhere? Back to the Arrow for SATs for a while. Does anyone need any specific grids in Michigan I am willing to go activate on the arrow early mornings or nights. Mike Kb8zgl

>From ray w6fya for Elk Antennas Craftsman makes a small strap wrench that I have used to remove elements that were stuck by the use of too strong locking compound. It sells for around $5.00 There should be other manufacturers of strap wrenches that could be used. Apply the strap near the threaded end of the element, not farther than a half inch from the boom. The threaded insert should prevent collapse of the tubing. I recommend not using a pliers, it will chew up the outside of the tubing. Proper use of the strap wrench should apply enough torque to remove the element. The recommendation of the use of copper particle anti-seize compound is good. Any other suggestions ?

AO-51 Field Day
by Gary "Joe" Mayfield 03 Jun '10

Just to be clear. AMSAT rules --- one contact on AO-51 mode V/S, and one contact AO-51 mode V/U ARRL rules --- one contact on AO-51 period. When I asked the ARRL for a ruling a couple years ago this was the answer I got. One contact on AO-51 regardless of modes. Is AMSAT allowing two? One on each mode. 73, Joe kk0sd

Arrow antenna will not unscrew, help
by Bill Dzurilla 03 Jun '10

03 Jun '10

We are leaving today for Europe and of course I waited until the last minute to take down my Arrow antenna, which has been mounted outside for about a year. But, when I attempted to unscrew the elements, they would not budge, even after receiving a big dose of WD-40. And the elements are not that solid so it's not possible to use a great deal of force. Is there some trick to unscrewing these things? 73, Bill NZ5N (soon to be OM9ACA, look for me on AO-7)

Alt-Az telescope mount for Antenna
by saguaroastro＠cox.net 02 Jun '10

02 Jun '10

Hello all, I'm new to the boards here and was browsing through and saw a post a few weeks ago about using an Alt az Telescope mount as an antenna rotor. I didn't see a response so I'll add my .0661 Malaysan Ringgits based on my experience as an Amateur Astronomer. First I have to presume that the OP already has the mount in question as a purpose made rotor could be had for a lot less money. First I'd think wind load on a typical antenna wouldn't be that much, but I would mount the antenna with it's center of gravity as close as possible to the elevation axis. Since a telescope would be mounted with its CG ON the Elevation axis, you'd want to keep the Antennas CG as close as possible to minimize and torque loads on the gears. I'd also use a sturdy dovetail mount, though that being said it looks like the mount in question is more than capable of handling the weight. Also make sure that the antenna will clear all aprt of the mount though it's entire range travel. As for tracking, I'm not sure if it will track fast enough. I couldn't find any specs in that regard. I know the Meade Autostar can accept Keplarian elements and track sats. Quite frankly it looks like a pain to upload them and I've never tried it, though I've been tempted. Since I've gotten interested in working the birds (Still have yet to make a QSO, Building an antenna and amassing the needed equipment), I've been looking at my Orion EQ1 German mount as a possible rotor. It's a basic Mount and I've figured if I mount the antenna with the beam paralell to the Dec shaft, alI have to do is set the lattitude comlimentary to the Max elevation (90 Deg - Max El) and point the RA shaft opposite the Max Elevation Azimuth, it will track the path of the sat. It won't track using the Clock drive, but I should be able to keep up using the slow motion controls. That being said, substututing a faster motor shouldn't be too difficult for a later project. Hope this helps. Now if someone could show me how to reply to thread on the archives...... 73 Rick K7TEJ DM33vq

Field Day AO-51 configuration - another option
by Patrick STODDARD (WD9EWK/VA7EWK) 02 Jun '10

02 Jun '10

Hi! With all the talk about the possibility of an L-band uplink and/or S-band downlink on AO-51 since there will be at least 2 other V/U FM satellites available during Field Day weekend, what about sticking with the V/U frequency combination but go with something different for the 2m uplink mode? Using SSB or even CW on the 2m uplink would make AO-51 different than the other V/U satellites, yet still provide a challenge that more stations could take on than L-band or S-band - and the variety that Drew mentioned that the AO-51 group wants to provide for Field Day weekend. Just a thought... 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

In the event that anyone at Camsat sees this mail ... It would have been nice with a SITREP - (situation report) - about the weekly schedule for HO-68. here are a *LOT* of people 'wondering' ... I summise it has something to do with the President of China visiting the ground station and Alan Kung being in the entourage ... but still, a SITREP would have been nice. On behalf of the myriad of satellite operators in Europe I would apprecate some word on the current status of HO-68 ... at your convenience. Thank you. 73 John. <la2qaa(a)amsat.org>

Doppler Tuning Convention Question
by John Belstner 02 Jun '10

02 Jun '10

I know there is a lot of discussion on this subject in the AMSAT archives, but I've recently read a few posts to the BB that have me confused. Just this weekend I got my Sat station on the air (FT-736R w/MacDoppler) and I noticed that the MacDoppler program I use adjusts both the TX and RX frequencies during the satellite pass. I'm assuming this is to keep my signal located in the same place in the transponder. The program seemed to work quite well. I was able to copy several QSO's on VO-52 and made a couple contacts as well. One thing I noticed is that about half the QSO's I copied did not require any manual tuning on my part (MacDoppler adjusted the RX correctly) while the other half did. According to MacDoppler, those that did require manual tuning were moving around within the transponder passband. I've read a few posts (one as recent as today) that suggested the convention is to keep the RX frequency fixed and manually adjusting the TX frequency while monitoring the downlink. Looking through the AMSAT archives this is the old convention prior to the popularity of tracking software and CAT control. So my question is, are there two conventions? or do I not have my software configured correctly? Sorry for what might seem like a stupid question, but I'm a newbie to this facet of Ham Radio. BTW, I'm having a blast! Cheers, John Belstner w9en(a)arrl.net

FS: Standard C1208DA FM radio-good for FM and packet sats
by John Geiger 31 May '10

31 May '10

I have for sale a Standard C1208 2m radio with wideband receive. It will receive on the 70cm ham band, as well as 800mhz for public service, and plenty of other frequencies. It does 50 watts out on 2m and will do dual receive. This is the model that has the display and controls on the microphone. It also has a data in and out jack to use for packet and APRS. It comes with the mic unit, a power cord, and the manual. THe dual receive and 70cm receive makes it very good for satellite use and it will do full duplex. The data jacks also make it very user friendly for the packet satellites. Those of you familiar with Standard radios know that they were by far the best FM rigs on the market, with a price to match that. I am asking $140 plus shipping and can take paypal/check/MO. 73s John AA5JG

My candle site is at ... http://www.soytives.com -Clint Bradford, K6LCS P.S. - Yes, this is a commercial solicitation.

QRM from Italy on AO-27

Hi in Italy, I just listened to a pass of AO-27 with AOS at 1406 UTC here in Copenhagen. There were 2-3 Italian stations on in terestial communications. They were radio amateurs using calls - but too fast for me to make out. IW9??? and IZØ???. I am not sure but may be it is a repeater. There were a distinct 67 Hz tone on. I could make out two city names: Catania and Modena. If some satellite users know what it is please try to make them stop. Have a nice Sunday. 73 OZ1MY Ib

UO-22 just 100000 on 3rd Aug 2010

UO-22 1 21575U 91050B 10148.66466669 -.00000020 00000-0 77105-5 0 8445 2 21575 98.4922 98.6195 0008358 67.4032 292.8038 14.39719412990416 The above kep is 'NORAD TLE Sets Current Data'. The orbit number is 99041, so 959 to 100000. 100000 - 99041 = 959 ... orbit numbers until 100000 959/14.39719412 = 66.61020140 ... orbits/mean motion = days 148.66466669 + 66.61020140 = 215.27486809 ... epock time The epock time 215.27486809 is 06:35:48 UTC, 3rd Aug 2010. It maybe contains +/- one and a half hour's obserbational lag. In addition, the counter number returns to 0 when the orbit number exceeds 100000. JE9PEL, Mineo Wakita

P3E/P5A S -> X transponder
by Michael Fletcher 29 May '10

29 May '10

Hi all ye Microwavers, AMSAT-OH is working on the S/X band coherent/linear transponder for P3E. The Coherent mode is a fully functional testbed for the P5A ranging transponder. Especially the linear transponder prototype has been assembled and verified with over-the-air tests and laboratory tests. Flight versions of the submodules have been and are being produced at this time with our eyes now set on integrating these together and cabling the whole job together. Full verification of the Coherent Mode requires a fully functional command station AND a functional IHU + CAN environment to interface our data ports with. No such tests have been available yet, but all our preliminary testing and evaluation of the Coherent Processor have shown proper operation of the design and circuitry (e.g. locking onto a "modulated" uplink carrier, tracking this etc.). So far correct live operation of the Coherent Mode is our biggest questionmark. Our national team meets on a regular basis every 4 - 6 weeks for testing and followups of the work of each individual. This transponder is especially complex as you can see from these key figures: * 9 different local oscillators * All local oscillators locked to the common 10 MHz USO * 21 different frequency mixers * 13 different intermediate frequencies * Linear Mode output power on 10 GHz: 3 W PEP * P5A Mode output power on 10 GHz: 1 mW PEP * 38 control lines on the CAN interfaces * 2 CAN interfaces, one in multiplexed mode * 4 dedicated direct control lines interfacing with the IHU * 14 analogue telemetry lines to the CAN bus * Coherent Mode Uplink/Downlink ratio is fixed at 30:7 Here you may find a general outline webpage, though unfortunately in Finnish for the benefit of our OH supporters, but you might still enjoy the photos and drawings: http://www.rats.fi/rats/amsat-oh/ Our team sincerely hopes funding will eventually be found for P3E/P5A - this is the only thing that keeps us motivated to continue our work. On the other hand we are clearly behind schedule, so the delays are welcome :-) But then again, any news of progress would boost our production rate phenomenally ;-) 73 Michael, OH2AUE -- "Life is too short for Sudoku"

Hi, Today I made an exciting experiment together with my friend Tetsu san JA0CAW. Since we can't hear NEGAI* in Central Europe we established a live link between our stations. Tetsu gave me access to his PC via remote control (VNC) and I could control his transceiver. We established a second connection via skype for audio. The audio quality was excellent and I could hear NEGAI at a 10 deg pass over the Pacific Ocean :-) See here: http://www.dk3wn.info/p/?p=15176 73, Mike DK3WN

Hi, I came across the post below on a Usenet group. I am only a very occasional ISS APRS user, but have noticed several of the regulars here when I do operate. My impression is that it is either largely a non-problem, or better solved through the APRS client. Can anyone suggest a good answer which I can cross post? Alan WA4SCA ============================= I want to somehow disable the PTT on my TX from SatPC32 when the satellite is below the horizon. This is very pertinent to running APRS through ISS. At present I have to be stop my APRS program and restart it manually at the correct times and I keep missing passes. I suspect I would need to use DDE to link to some sort of port control program or maybe via rotor control but am not experienced in using DDE. Is there any SatPC32 guru who can make some suggestions? Thanks from Dick G4BBH

Alinco DJ-G7 Full Duplex
by Ian MacFarquhar 28 May '10

28 May '10

Hi everyone, I was wondering if someone on the list could tell me whether or not the Alinco DJ-G7 handi will now work full duplex ? I had one of the first ones and it would not operate duplex due to receiver desensitization and I sold it. Now I have been told by another ham that with the new software download the DJ-G7 should work fine. Is this correct ? Thanks & 73, Ian VE9IM FN75ak

AMSAT Donations
by Clint Bradford 28 May '10

28 May '10

BOB>> ... eBay helix ... AMSAT will be getting close to $200 with the D.A.R.A matching fund ... For those not counting - and Bob is not one to gloat - this means that Bob has been responsible for AMSAT receiving darned near $1,000 in the past couple of weeks. Donations may be painlessly made online at the AMSAT Store - where your $25 donation gets doubled to - yes, $50. Or sell a spare radio to your local ham club. It will be put to excellent use - you're not using it (that's why it's a spare gathering dust) - and send off the proceeds to AMSAT for DARA-Doubling! Heck - I am looking at a Diamond X-30 SO-239 NEW IN THE BAG that I really have no use for ... SEE NEXT POST FROM CLINT! Clint, K6LCS 909-241-7666

AO-7 is not OK
by ps8rf Piraja 28 May '10

28 May '10

Some days we are seeing very strange behavior in the AO-7. In some orbits can only hear the feedback on the downlink when the satellite is approaching my station at about 30 degrees elevation, before is impossible to hear any signal via AO-7. Using two pre-amplifier, one in the TS 2000x and the other with 0.6 noise with 20 dB gain. During the orbits we transmiting power with of 30 watts. The satellite does not respond. Tried with 15 watts It was then that we hear at certain points on the downlink audio too low. Its best performance is when the satellite is almost 90 degrees from my station. Yet it seems that the satellite is asking for help. This seems the batteries are not getting enough loads. Or maybe it's excessive use of power by the users of the satellite. Maybe it's time for the users of AO-7 rethink the best ways to keep QSO through it, such as the use of LOW POWER so that over time the satellite is stabilized. "Long live the AO-7" 73' Piraja, PS8RF The Amateur Radio is supportive and helpful in any circumstance. _________________________________________________________________ Você sabia que seu navegador te ajuda a ficar longe de vírus?

ZW8B - IOTA SA-025 & LIGHTHOUSES ACTIVATION - NEXT WEEK.
by ps8rf Piraja 28 May '10

28 May '10

Hello All, On June 1 a part of the team ZW8B arrives in Santa Isabel Island. Our intention is to work a greater number of days in the communications via Satellites. Our prediction is that we are still active in the satellites in the early evening of June 1 in the satellites ( AO-51 VO-52, SO-50, FO-29, SO-67 (if active), HO-68 and AO-7 A and B ). It's a good chance to work via satellite, a Brazilian amateur station and a rare grid. We hope to make a grand party of DX , especially for the community of satellite operators. On line Log: http://www.clublog.org/charts/?c=ZW8B Teresina Dx Group: http://www.teresinadxgroup.com/theDX/ 73' Piraja, PS8RF _________________________________________________________________ CANSADO DE ENTRAR EM TODAS AS SUAS DIFERENTES CONTAS DE EMAIL?
