[Skimmertalk] WSJT-X skimming load balancing?

Tue May 5 15:32:41 EDT 2020

Can't speak to FT#Startup (don't use at all since multi-band FT8 decoding
is provided off line by a dedicated RP-14 using SM7IUN's setup instructions
<https://sm7iun.se/redpitaya/ft8skimmer/>), but Aggregator 6.0 starts
SkimSrv and RTTYSkimServ and SkimSrv2 automatically for me, in proper
sequence, with hardly any problems.  It's true that the second instance of
SkimSrv (SkimSrv2) has to wait a bit for the first instance to be running
before it will cleanly start, and if I restart SkimSrv I have to restart
SkimSrv2 "manually" (using the Start button in Aggregator) , ut the
"Associate Programs" tab in Aggregator 6 does all that quite nicely.

Let me know if you can't figure it out and I'll help you get set up over
TeamViewer.
