Tacking onto the conversation. Are you suggesting to add at least some squelch? I usually have it wide open with the D72A. Uplink I usually leave fixed and adjust for Doppler based on the rudimentary RX meter within the D72A.
Another question, I see CON flash on the D72A. Do we always need to be logged onto the PBBS or is log on/off normal? It’s hard to keep a CON especially for a non fixed portable station. Not sure how the PBBS treats this connection and the CON is only for uploading ?

Stephen,
You are right. A partial upload will be deleted after a few days. Probably something like 3 days, I can't recall.
Keep at it. Maybe drop the file size of your upload attempt and see what you can do on a single pass, and try more as you optimize?
It's all about signal to noise...the good news is that FS-3 has a great receiver, so it doesn't take a whole lot of uplink gain. Adjusting for Doppler on both uplink and downlink is important, as is deviation of the uplinked signal. Try lowering the audio level until it's just audible. On a receiver, it should sound like "half" of just an open squelch, rule of thumb/ear!

It looks like if it doesn't complete the upload in a certain amount of time or passes, the file gets lost. This must be a housekeeping function on the satellite side. For example, today I get:
Open ABCD: Ready to upload file: N8URE18.jpg.out B: 715788744. U>> From:PFS3-12 to N8URE Ctrl: 63 Type: UA Res PF: 0 NR: 0 NS: 0 I>> SUCCESSFUL LOGIN to PFS3-12 by N8URE I>> UL ERROR 4: ER_NO_SUCH_FILE_NUMBER Bad File Number, will ask Pacsat for a new number on next attempt: /home/scalar/Falconsat_data/FalconSat-3/N8URE18.jpg.out Open ABCD: Ready to upload file: N8URE18.jpg.out B: 715788744.
It got to the "Ready to upload" point a number of times on the pass, but then wouldn't get past that stage. For example
Ready to upload file: N8URE18.jpg.out B: 715789771. PB: Empty..
and then it moves on to something else. There were a lot of stations on the pass, which I'm sure didn't help.
