IC-9100 SatPC32 Sub Audible Tone for SO-50
by Fraser Bonnett 01 Jul '15

01 Jul '15

Frank, Check the auxiliary file SubTone.SQF In mine, there's one entry for SO-50 "SO-50,67.0,$3F,1" It works for my IC-9100 73, Fraser, W3UTD I have acquired an ICOM IC-9100 and am stumped on how to program SatPC32 to select the correct sub audible tone for SO-50. I have studied the SubToneSQF file and the ICOM manual. When I click on T0 and change it to T1 or T2 in SatPC32 the sub audible tone is turned on in the IC-9100. The tone frequency in the IC-9100 does NOT change to the value in the SubToneSQF file. Has anyone figured out haw to correctly setup SatPC32 SubToneSQF file to work with the IC-9100? Could you post the correct command line so I could copy it into my file? Thanks in advance for any guidance.

We have been working on getting the sat contacts formatted properly to be accepted by LOTW. Two uploads last week did not work. We have further edited the file and will upload again tonight or tomorrow. We will post here when we are successful and see some matches. Jim Jim White WD0E(a)amsat.org jim(a)coloradosatellite.com

Hello, Want to say hello to all members in this my first post to this BB. Also, want to say thanks to Tom, W9KE, for the message on the board about my tracking and positioner project that was just published in the latest issue of the AMSAT Journal. As a follow-up to the article I have updated my web page with some detailed information on the CNCTRK system and on the AZ/EL APS, here: ki4sbl.dodropin.org/CNCTRK/ . If there are questions, omissions, or feedback, I'll be happy to hear from you. Thanks and Have fun! 73, Bob KI4SBL

There was a NO-84 / ISS double hop opportunity this evening between 00:55-01:05utc. I was able to send packets both directions, but did not see a double hop. Both spacecraft were in view of each other as well as an i-Gate. There is always next time. KO6TZ BOB

PSAT Satgates in Eastern USA?
by Robert Bruninga 30 Jun '15

30 Jun '15

We need more Tracking Satgates in the eastern USA: During the last pass Solidly over Eastern USA and dozens of packets and many users, only two packets made it to the APRS-IS. So there seems to be a paucity of Oscar class SatGates at the moment.. Of course tracking and gain antennas are not needed for SatGates for the ISS, but are essential for PSAT. So if anyone in the USA has rotors and wants to exercise them and put a little wear and tear on them for the next week or so, please feel free to come on line. We are trying to get PSAT properly set up for its attitude control and for it to know where it is, and we need more data for a while. We are getting solid data horizon to horizon over Europe, but very little over the USA. I completely understand the usual need not to keep rotors running for routine. That is why we want to develop the Omni Satgates. But until we get enough of them on line, we welcome more conventional tracking SatGates for a while. Thanks Bob, Wb4APR
