SB SAT @ AMSAT $ANS-266 03 GO-32 enabled for experimental APRS access

AMSAT News Service Bulletin 266 03 From AMSAT HQ SILVER SPRING, MD September 23, 2007 To All RADIO AMATEURS BID: $ANS-266 03

The GO-32 Satellite TECHSAT-1B team has announced experimental 9600 baud APRS access for mobile and tactical APRS on a not-to-interfere basis with the existing PACSAT BBS

The uplink is possible with 5 Watts on 2 meters, but the downlink is 9 dB worse to an omni antenna on UHF and requires tuning 10 to 20 KHz for Doppler Currently there are no permanent IGates to bring the downlink into the global APRS system, but it is hoped volunteers will surface with permanent satgates So initally, do NOT expect to see yourself on FINDU COM Enjoy ham radio, Make a contact instead!

Experimental testing shows that an APRS HT with a 19 5" whip can get a lucky shot into this satellite (but not when there is congestion on the uplink) With a handheld beam, it should be no problem for an HT, and the beam is needed on reception anyway Fifty Watt mobiles should have no problem using a stock mobile whip Due to the absence of APRS signals to date, we do not have good statistics on reception in a mobile yet

Operating on a 9600 baud FULL DUPLEX APRS satellite is MUCH different than ARISS, or any of the other 1200 baud APRS PCSATS Because the turn-around is so fast, you cannot see your own digipeated packets on the same radio (usually) Please read and understand this entire bulletin before attempting to operate

The easiest way to get on GO-32 with 9600 baud APRS is to use a Kenwood D7, D700 or D710 radio These radios since 1998 have been satellite 9600 baud ready, just waiting on a satellite!

Read these notes on how to operate GO-32 with a D7 or D700:

Set APRS Baudrate to 9600 baud
Set A band to uplink on 145 93 Set B band to receive 435 225 +/- 10 KHz Set Path to be via 4XTECH Set MYCALL to a unique SSID Set TX method to AUTO Set TX RATE 1 min for HT 2 min for D700 Put something useful in your STATUS text maybe describing your setup: "50W mobile, 1/4 wave, 2m rate" or "5W HT, long whip, 1m rate"

Save in a PM for use anytime you are outside of the terrestrial APRS network

SATELLITE OPERATING NOTES:

The GO32 uplinks and downlinks are for the PACSAT store and forward system and users APRS use is on a secondary basis and should not be operated unattended If you see that the BBS PBLIST is full of other users, do not enable your APRS since the uplink will be busy Currently the PBLIST is not in APRS format so you cannot see it unless you are running normal packet mode

On the D700 you can press PMON on the front panel and see these packets but they FLY by

ACCESS TIMES: GO-32 is sun synchronous and so it comes over everywhere three times between about 8 AM to Noon and again between 8 PM to midnight local sun time During these two windows at least one pass each will be an overhead pass which might also work for an HT The other passes will be lower to the East or West and will work fine for a 50W mobile

WHAT YOU HEAR: 9600 baud sounds almost exactly like open squelch, though the tuned ear can soon distinguish the difference Before the pass, set your squelch normally to quiet the speaker When you hear the satellite, the squelch will open and you may see up to 3 bars on your S meter Tune to the "best sounding" noise

DOPPLER: Depending on how low to the horizon you can see, the satelite approaches 10 KHz high at 435 235 MHz But it is maybe 3000 km away As it gets higher, and 6 dB closer, it will be on 435 230 MHz, passing through 435 225 published center frequency at the middle point, and then drop down through 435 220 and ending at 435 215

But since it is 6 to 10 dB closer (and stronger) towards the center of the pass (800 km overhead), the mobile antenna is probably only going to hear the middle 435 230, 225, 220 portion easily So I would start my receiption at 435 230

UPLINK CHANNELS: GO-32 allows two APRS uplinks One is exclusive to D7/D700 tactical position reporting and the other exclusive to messaging This is in hardware, not policy

1) All APRS messaging (or fixed station non-Mic-E positions) must use the 145 85 uplink where GO32 only digipeats APRS packets with TOCALLs that begin with the usual "APxxxx" (Even the D7 and D700 use "APKxxx" for messages )

2) All APRS Mic-E position uplinks (D7, D700 and D710s) must be on 145 93 MHz and they must have the position comment set to "Committed, Special or PRIORITY" With those comment settings then the TOCALL first LATITUDE digit will be 1,2,3,4,5,6,7 and only these will be accepted by GO32 for digipeating from 145 93

DATA CARRIER DETECT: The D700 and non(g) model D7's will NOT TX if they are hearing the downlink at the same time due to CARRIER DETECT The D7(g) model has DCD IGNORE that will let it TX anyway So use separate rigs for TX and for RX if you want to see yourself

Otherwise stick to the receommended TX rates and know that you are getting in if you stick to the protocol Sticking to the recommended rates also keeps channel loading low, so that everyone gets in with less congestion

PERMANENT SATGATES: Here is a great place to use your D7 HT when you are not using it otherwise Simply connect it to a 19" whip over a ground plane and to your APRS IGate system The antenna does not even need to be high, since it cannot hear, nor will it be on frequency for low packets near the horizon 3000 km away Set it to 9600 baud RX and tune to 435 230 (which is 5 KHz high) This Doppler setting will match the stronger signals

This 19 5" whip (3/4 wave on 435) does not need to see below 25 degrees, since its max gain (almost 7 dB) is between 30 to 70 degrees anwyay This also protects your HT from lightning, since it can be low, below all of your other antnenas Yes, your station will only see about 30% of all possible packets and only on the best two passes per day, but combined with dozens of other such unattended SATgates, all packets should be heard somewhere by someone and injected into the APRS Internet system

Bob Bruinga, WB4APR, reports that he hopes to have an APRS-via-GO32 web page up in a few weeks
