Kenwood TM-D710G TNC Cable?
by Tony 01 Dec '20

01 Dec '20

All: Does anyone know if the Kenwood PG-5H programing cable is the same as the PG-5G used to connect to the internal TNC on the TM-D710G? The manual is a bit vague on whether the PG-5H that connects to the rear of the radio is the same as the PG-5G that connects to the front panel to access the TNC. Tony

Re: [amsat-bb] SatPC32 - need help with configuration of Doppler.SQX file

NOR instead of REV is the problem. Had exactly the same symptoms you describe on CAS-4A and B because they were set to NOR.

Thanks Frank, saying to move to 145.825 in fact I forgot all the other problems but it is certainly a local problem in some areas. So our only hope is that these repeaters will not be renewed or converted to digital. Thanks anyway for the reply. 73 Carlo IK5JRZ. ----Messaggio originale---- Da: ka3hdo(a)gmail.com Data: 30-nov-2020 22.29 A: <ik5jrz(a)tin.it>, <fabrizio.carrai(a)gmail.com>, <amsat-bb(a)amsat.org> Ogg: RE: [amsat-bb] R: Re: ISS SSTV frequency All, We CANNOT move the ARISS SSTV frequency to 145.825. This is being used for other satellites employing APRS and we would interfere with their operation. Prior to their being an ARISS station on ISS, we conducted an extensive, international effort to ensure ARISS had a clear downlink on 2 meters. We worked with all IARU regions and concluded that the best world-wide downlink frequency for Human would be 145.80 MHz. At the time (1997) the United States had terrestrial APRS on 145.79. In the USA we worked with the APRS community in a collaborative fashion to QSY APRS terrestrial from 145.79 to 144.39 (where it is today). This was a HUGE effort and required many digipeaters, several on snow covered mountains, to be modified or replaced. Donations were collected. And AMSAT-NA and TAPR worked together to make it happen. Again, please note that IARU region 1 agreed with this downlink frequency for human spaceflight many years ago so we could have one common downlink. I am very sorry you are experiencing this. I think this will take local coordination to resolve this. Similar to what we did for terrestrial APRS. Trying to move ARISS around in the very small OSCAR 2 meter sub-band (145.8-146) is virtually unworkable, given the many 2 meter satellites that are employing this band. I hope this helps explain things from an ARISS perspective. Back in the day, I was given the unenviable task of working these frequency coordination issues for human spaceflight. To be clear, we are much better today than some of the issues we were experiencing in the past. And changing things around will probably make it worse for ARISS and other users in the satellite community. 73, Frank Bauer, KA3HDO Chair, ARISS-International -----Original Message----- From: ik5jrz(a)tin.it <ik5jrz(a)tin.it> Sent: Monday, November 30, 2020 2:36 PM To: fabrizio.carrai(a)gmail.com; amsat-bb(a)amsat.org Subject: [amsat-bb] R: Re: ISS SSTV frequency Thanks for answer, The repeater is R7a (Monte Secchieta), it's not only an Italian problem unfortunately, I have read many complaints in other areas as well. I don't question the correct spacing between frequencies, but I'm afraid it's only on actual paper. I don't want to doubt that the repeater is working correctly, but I think that if the ISS transmitted at 145.825, since when it transmits in SSTV APRS is disabled, the problem would be solved. The video demonstrates the proximity between the frequencies even if I admit to being in the high area and to receive the repeater very well. https://www.youtube.com/watch?v=nsoSjh54a3A&amp;ab_channel=IK5JRZThanks again.

Thanks for answer, The repeater is R7a (Monte Secchieta), it's not only an Italian problem unfortunately, I have read many complaints in other areas as well. I don't question the correct spacing between frequencies, but I'm afraid it's only on actual paper. I don't want to doubt that the repeater is working correctly, but I think that if the ISS transmitted at 145.825, since when it transmits in SSTV APRS is disabled, the problem would be solved. The video demonstrates the proximity between the frequencies even if I admit to being in the high area and to receive the repeater very well. https://www.youtube.com/watch?v=nsoSjh54a3A&ab_channel=IK5JRZThanks again.

The R7a is indeed at 145.7875 Mhz with a bandwidth of 12 Khz there shouldn't be any interference (in theory). Have you checked which repeater is in your (our) zone ?
