PSAT2 PSK31
by Stephen DeVience 29 Oct '20

29 Oct '20

Has anyone been able to get a PSK signal through PSAT2? I'm trying to get set up to try SSTV, and I'm first trying to get a PSK signal through. I only have 5W, but I've been able to get into PSAT (NO-84) and hold its transponder on both with and without DopplerPSK. I have not had any success using the same procedure with PSAT2. I was using DopplerPSK and was sure to change satellites to NO-104. It could just be that the passes are lower and more power is needed. I also want to confirm that the frequency is 29.4815 MHz, as there are a bunch of different frequencies listed at various sources. Thanks, Stephen N8URE

I think they are never called "dead" until they re-enter). Also, it seems to turn on now and again (it was on and being used about a week ago, according to SatNogs observations and the amsat status page). I've also caught at least one pass where it was partially on (I caught what appeared to be a beacon, but with no DUV telemetry - and it was weak and didn't sound right either), about 2 weeks ago. The problem seems to be battery life issues, btw. --Roy K3RLD

ISS Cross Band Repet
by Joel W9NXM 25 Oct '20

Just starting out to chase the ISS with it's new cross-band repeater. I've noticed that for the last 2 weeks, there has not been any FM activity on the ISS_FM status page. Is there somewhere I can find out the schedule of it's operations? And likely when it will be available? Thanks much! Joel, W9NXM, EN52

Neat view of a rocket launch from space. I suspect this is viewed from the ISS. https://tinyurl.com/y26qcpp8 --- Zach N0ZGO

K5Z from DL88 was on the 1525Z pass of XW2A running CW so they are on the air! Good luck to everyone-they were a new grid for me! 73 John AF5CC

Re: [amsat-bb] All-Mode Satellite Transceiver Choices?
by Chris Busch 25 Oct '20

At the risk of posting something that is already known, I would agree that success with 9600 baud is a matter of both a transmit and receive audio/data bandwidth of 8-12 kHz, which unless that is under SW control in your particular radio, it can’t be addressed with a FW mod. I have successfully moded both Yeasu FT-726/736R (many years ago) and more recently, the Icom 970 by accessing the FM discriminator and modulator directly and bringing those signals via shielded cable to either an added connector on the rear panel or utilizing unused pins on one of the existing rear jacks, which is then attached to an external TNC. In the case of the Yeasu, I also changed the IF filter to wider BW. BTW, that added IF BW in FM mode on the Yeasus when not using 9600 packet was a compromise for FM voice, but worthwhile for me. I know that performing surgery on a new expensive radio which is still under warranty may be scary, but it’s the only answer I have found, and it actually isn’t an extensive mod - just soldering the cable(s) directly to the appropriate points. Since I don’t own a 9700 (still using the IC 970), I haven’t looked at the schematic to locate the appropriate attachment points, but maybe worth a look if you can’t find another option and 9600 is critical for you. Here’s a link to the mod for the 970 for reference as to what is typically required: https://manualzz.com/doc/23724528/modifications-for-the-icom-ic-970-ic (it’s the 2nd mod down) 73, K4CKB (Chris)
