Hello all,
Got all your TESTING UPLOAD messages in loud and clear. My message to K4KDR didn't get send out. I'm still (re)searching about the cause of this. Later......

Hi Hans,
I was able to upload a message (to you!) on FS-3 last night/this morning, fully automated. So the satellite is evidently behaving OK.
Hope you get it figured out. Since I don't use Direwolf, sorry I can't give any suggestions.

I didn't write it directly, but I assumed from the description you would read that I indeed run full duplex (and to add to this: my system is Linux, not Windows). If not Direwolf will wait for a free window to throw out packets which will never happen because FS-3 is on all the time. No, everything is working, except for the problem I described before: all commands to the bird are heard and responded to, but uploading a message will fail.
Desensing is also not the problem: got the appropriate filters in place for that. Cheers,

Hello Hans, I have not been working FS-3 recently, since the IC-9700 will not do 9600 packet [iCom, please fix!!] :(   So I cannot comment on recent uploads. However, to add to Bob's thoughts--are you running full duplex?  It's critical. Also, is your transmit signal desensitizing your receive signal?  That is important, too.Â
In the next week or so I will change radios at my station so I can again use FS-3. Â I'll be better able to share current experiences with you.

I'm not behind my shack computer right now, but I know that PSGS and Direwolf each have a TX delay. Are you referring to those maybe being too long? If so, then why are all other commands (DL and directory listings) giving me no problem? 73 de Hans BX2ABT On 06/17/2019 08:53 PM, Robert Bruninga wrote: > I am no expert. But remember that your RF and all processing has to > be full duplex. The turn arround for packets in the satellite is > instantaneous. > with no TXD delays. Bob > > > On Mon, Jun 17, 2019 at 2:24 AM Hans BX2ABT via AMSAT-BB > <amsat-bb@amsat.org <mailto:amsat-bb@amsat.org> <mailto:amsat-bb@amsat.org <mailto:amsat-bb@amsat.org>>> wrote: > >   Up til now I have been successful in getting PacSatGroundStation >   (PSGS) >   to work on receive.
