The EDM Group completed a very active nationwide exercise on Saturday, March 25 utilizing VarAC as a "call-up" tool to locate and activate EDM Target Station Team members that might be available for HF P2P Winlink messaging after a major disaster had rendered the Internet, Cell Service, repeaters, and virtually all other infrastructure useless.
We collected over 100 pages of logs from participating stations and will be analyzing the resulting data for future planning.
One thing I noticed is that after several hours of operation, VarAC no longer reliably keyed the transmitter. It would drop out of transmit mode before starting the "send" sequence. When switching to other software (noticeably WSJT-X) the problem disappeared. Any thoughts?
I am not familiar with this issue. VarAC works for weeks on my PC without restarting without any issue. IT may be related to a lack of resources on the hosting PC or something else. I would need to collect additional info when this happens including VarAC log (debug mode preferred that shows CAT commands and RIG responses) as well as some metrics from the host like CPU/MEM avilable.
