1707z PSAT pass
by David W0DHB 05 Jun '15

05 Jun '15

This last pass of PSAT (26deg peak here) I could see packets but never strong enough to decode. I know from APRS.fi that some folks are copying. Also noticed that end of the pass it appeared on the waterfall it was digipeating me, but I couldn't decode. I will try again 1846z pass which is 49 deg here. Dave W0DHB

Best Mast mount PA/LNA?
by Robert Bruninga 04 Jun '15

04 Jun '15

What is the best mast-mount PA / LNA on the market these days. Our old TE Systems amps are now over 15 years old and have only mildly been protected from the weather. Since I am not hearing as well as some other stations, maybe it is time to replace/upgrade? The TE systems had a low noise preamp for receive and 100W amp for TX. We need the amp because we have 150’ of coax to the roof. Do they still make ‘em? So whats out there? Bob, Wb4APR

I displayed 5 telemetry packets, could not digi any packets, this was a nice 22deg pass. Also I did not see anyone else digi any packets. Is the APRS Digi turned on and working for anyone else ? The <UI> path says APRSON.

change in the activation of the ISS digipeater usually in South America with RS0ISS , RS0ISS -1 could activate your digi, but now is working with " ARISS " 73s and good contacts ! LW8EXS

Latest PSAT pass
by Steve Kristoff 03 Jun '15

03 Jun '15

Did a little better on the recent PSAT pass (1710 - 1722 UTC). I received three telemetry packets (the spin telemetry packet made it to the list on pcsat.aprs.org ) and a packet from K1WY. Did not receive any acknowledgments of my transmitted packets. Steve AI9IN EM79ji Oldenburg IN

Re: [amsat-bb] WD9EWK @ Show Low AZ hamfest & weekend grid expedition (6-7 June 2015)
by Patrick STODDARD (WD9EWK/VA7EWK) 03 Jun '15

Hi Dave! I'm not going to do much with PSAT this weekend. If there are PSAT passes when I have a break, I might give the 2m digipeater a shot. Otherwise, I'll try PSAT after the weekend. ISS passes, on the other hand, will be attempted if I'm not driving. Please use APRS messages, or insert a ">" before typing a line of text, so that I see more than just your call on my screen. If I only see a call on my screen, even if you were typing at me, I won't log that as a QSO. I was not planning to do much from DM46, but Saturday evening via AO-73 is probably the best chance for that. Maybe Sunday morning, if I get up very early, where I can work an early FO-29 or AO-7 pass before I set out for DM47/57. I won't have the benefit of freeways in my travels up there, so I will need to watch my speeds on the highways across that part of Arizona (and southern Utah). I'm hoping the APRS digipeater on Navajo Mountain has some coverage where I'm going, being several thousand feet higher than the surrounding area. When I was last out this way in 2009, I didn't have anything for APRS with me. 73!
