SB SAT @ AMSAT $ANS-287 01 Certificates for AO-51 Sputnik 50th Anniversary Special Event

AMSAT News Service Bulletin 287 01  From AMSAT HQ SILVER SPRING, MD October 14, 2007 To All RADIO AMATEURS BID: $ANS-287 01

Kevin Schuchmann, WA6FWF, reports that he has started to receive the requests for certificates and is working on getting them out as fast as possible The response has been great so far People requesting a certificate should keep the following in mind:

1) this is not a small QSL card, it is a certificate that is 8 5" x 11", if you send a small envelope he will be forced to fold it

2) make sure you have enough postage

3) if you want to make sure it does not get bent, include a card board backer or use a heavier envelope

4) do not include money or stamps, I appreciate the gesture but it is not necessary,  donations can be sent to Martha directly

5) if you put "your" address up in the upper left coner as the return instead of Kevin's then in the event there is not enough postage it will be
returned to the sender instead of Kevin for additional postage!!

Kevin observed that, "based on the fact that my mailbox was full and the postman had to leave more at the front door I might need the couple weeks we said it might take!"

[ANS thanks Kevin, WA6FWF, for the above information]

SB SAT @ AMSAT $ANS-287 03 GO-32 mobile APRS access success

AMSAT News Service Bulletin 287 03  From AMSAT HQ SILVER SPRING, MD October 14, 2007 To All RADIO AMATEURS BID: $ANS-287 03

Bob Bruninga, WB4APR reports receiving over 150 packets from GO32 in the mobile and gives the following report

If you want to impress someone with handheld Satellite Communcications, just stand outside during the prime morning or evening pass of GO-32 with your D7 HT set for APRS 9600 baud receive on 435 230 (5 KHz high at the start of the pass) and watch the messages fly by Switch to 225 and finally to 220 by the end for maximum packets

Tonight I finally remembered to set my D700 in my van to the GO32 downlink  Was out doing honeydoos around 7:50 PM and heard a few squelch breaks  This would be the first evening pass  So that told me to be out 100 minutes later for the prime pass of the evening

I was not disappointed!  Received over 150 packes during the central 6 minutes of the pass  I was just making hash marks on the back of an envelope while watching the packets fly by on the front panel of the radio  I did tune 3 times for Doppler since I was just sitting there with nothing else to do

This confirms that an unattended D700 or D7 hooked to a simple OMNI antnena (and short coax) can make an excellent APRS satellite gateway  With say a dozen of these across the USA, then the APRS-Internet system should get a solid downlink!

After the fact, I came in and looked at the pass on Instantrack  Here is the nitty-gritty showing the elevation angle versus number of packets received per minute

TIME  EL  PACKETS 0933  30  18 0934  40  23 0935  46  36 0936  45  35 0937  36  24 0938  26  13

For an unattended ground station without Doppler tuning, my guess would be that this station would have received the center full 3 minutes of this 45 degree pass

So, what is your handy D7 doing sitting on your shelf turned off?  Hook it to a 19" vertical whip over a ground plane outside your window  and contribute to the National GO-32 APRS downlink system!

I'll get someone to write a simple turn-key APRS IGate background application, so you don't have to hasssle with all the other APRS stuff if you dont want to This way, you can just turn on the D7, hook it to a serial port, run this application in the background, and you too will be a contributor to the solid APRS downlink from GO-32!

Oh, On the D700, I had pressed the PACKET MONITOR button so that I was seeing all GO-32 downlink packets on the front panel, not just the APRS ones  The D7 does not have the PMON button, so you will only see the APRS packets  But I did receive the 3 APRS downlink bulletins perfectly many times, and every 30 seconds or so, I did receive the GO-32 TIME STATUS report on the front panel of the radio

So, even if you are not going to Igate, just hook that D7 to an outside 19" vertical whip (this serves as a 3/4 wave gain vertical on the 435 downlink) through a short coax (Antnena height does not matter, coax loss does!)  You won't hear anything below 30 degrees anyway  And just leave the HT on all the time tuned to 435 230  Every morning and every evening, you will receive GO-32 and any other APRS operators playing that evening

When you hear good signals on 435 230, then 2 minutes later, switch to 435 225 and so on  When the pass is over, set your radio back to 435 230 for the next HIGH pass 12 hours or so later

You can leaave this on all the time, since it will not wake you up  GO-32 PEAK passes are within an hour or so of 9 AM and PM local time (maybe an hour later after the change back to standard time)

Thousands of AMSAT folks have these D7's, and I bet that 99% of them are not in use most of the time  All we need are a dozen or so serving this space-diversity ground station function

[ANS thanks Bob, WB4APR, for the above information]

• Henk, PA3GUO, one of the control operators for the ANDE satellite   reminds amateurs that the packet-to-voice mode still remains avail-   able  A command from a ground station is required to enable this   mode so Henk invites amateurs interested in experimenting to con-   tact him by e-mail at pa3guo@amsat org

• Drew, KO4MA, AMSAT VP of Operations reminds amateurs interested in   experimenting with different modes on AO-51 to submit their request   via e-mail to ao51-modes@amsat org  One experimental mode under   consideration includes a day dedicated for D-Star testing via AO-51

• Special Events Station GB5OSO, celebrating the 50th anniversary of   the launch of Sputnik-1 has worked several stations through the   SO50, VO52, AO51, AO27, and AO7 satellites  Robert, G8ATE reported   a transatlantic contact between GB5OSO and Jim, VE1ZM on SO-50

• Earlier this year the Japanese Space Agency (JAXA) sponsored an   activity to fly your name to the moon aboard its "KAGUYA" (SELENE)   lunar probe  Selene has attained lunar orbit and JAXA reports   that messages from 412,627 people around the world are now at   the moon  For more information see:   http://www isas ac jp/e/snews/2007/1005 shtml
