A years or so ago, I had my SCS DR-7400 modem working with SDR 1.5.1. I have not used it for a while and tried to get PACTOR P2P working for the COMMEX last weekend. TX timing and latency see to reared it's head in 1.9.13. Could to get a reliable sync either send or reciveing. Setup below:
DIGIU at 5K
PROC=off (Default on DIGIU)
DEXP=off (Default on DIGIU)
Set Comport you are using to Active in CAT
TX delay 0 to 20 tried 5 to 80 with no successful results.
Radio software 12.9.13
Radio - Flex 6500
Band USB DIGITAL
Computer direct hardwired to radio (no hub).
Does anyone have an idea? worked before! $1,500 modem should work with a $4,500 radio. Many of us in MARS and emergency services rely on PACTOR and HF.
Thanks for any help!
