Looking at when the problem started, I'm assuming the problem is related to ISS turning off their packet systems regularly. Long ago I was able to operate ISS packet throughout the pass, even drop messages into their their BBS, etc., but for a considerable time now I have pretty much given up working with ISS packet. All other factors considered, the fact that your system gets ACK-ed on 144.390 is proof positive. It has always been a guarantee to be able to work ISS packet. 73! Umesh,k6vug

Posting this as a last resort as I ordinarily enjoy doing my own troubleshooting, but this one has me perplexed. For normal sat ops I am running a TS2Kx, 5 el 2m and 11 el 70 cm Directive Systems yagis on a G5400. Doppler and rotor all run by SatPc32. Up to about a year ago I ran AGWPE and UISS and a USB Signalink (through ACC 2) to dig over ISS. Never had a problem, except the occasional decode problem fixed by UX7HO Soundmodem. I finally removed AGWPE and began using Sound Modem with UISS. However, since then I have been unable to dig over ISS. I decode just fine. My transmissions sound like normal packet transmissions, listening on a second receiver. I have used all of the online recommended settings for both Sound Modem and UISS. I have played with the audio levels. I substituted Signalinks in case that was the issue. Also, I have no problem sending APRS over 144.39 using different "wide" settings and getting an acknowledgement back. My "neighbor" Christy KB6LTY has provided mu ch assistance, but still no joy. I am missing something. So I'm hoping someone has had a similar issue with a similar set up and can maybe send me screen shots of their settings that work, especially in Sound Modem. Or, any other suggestions would be greatly appreciated.
Thank you in advance
