I work AO-27 with a one watt ht and Arrow handheld antenna here in western Colorado all the time. Timing to get through the traffic and be heard, but once you are get ready for a pileup. Jim Adams - K0BAM

Re: [VX_8R] Has anyone had success doing APRS to the ISS?
by Bob Bruninga 02 Jul '12

>> I have tried ... but I don't see any response from the ISS... > It's temporarily on 437.550 > You also have to use a path like: ARISS,SGATE,WIDE2-2 That path adds 14 extra bytes to a packet almost doubling the length and therefore cutting throughput in half by doubling congestion. The only path necessary is simply VIA ARISS. In most countries there are numerous IGates listening to the downlink and making sure the packets get to www.ariss.net and APRS.FI without the added path baggage. Some have suggested adding the SGATE,WIDE2-2 on the end to force these packets from the SPACE frequency 145.825 over to the national APRS channel, but there they just collide with terrestrial traffic. I personally don't see the benefit considering the 50% overhead cost on the very precious 145.825 space freq. Bob, WB4APR

New AO7 world distance record
by Bill Dzurilla 02 Jul '12

02 Jul '12

I am pleased to report that Wyatt AC0RA and I broke the AO7 world record today with a GPS-measured 7849km QSO between JN88 and EN31 at 0955Z. A recording of the 40 second QSO is attached. Wyatt did all the hard work by waking up at 3am, driving to a hill an hour away from his home, setting up his station, and working me before sunrise. It appears that an even longer distance is attainable, and Wyatt is looking for a suitable place from which we can try before I leave Slovakia in mid-July. My working conditions are an FT847, 2 x 10 element yagi on 2m with SP2000 preamp, and an 8 element yagi for 70cm. Feel free to email me for a sked. 73, Bill OM3BD NZ5N

by johne tds.net 01 Jul '12

Hi , Will be soon constructing a digital interface for a Yaesu FT-3000M to hopefully copy SSTV from the ARISS . Should I use the 9600 data or 1200 data port or just use the audio out? Thanks de John KØCQW
