I got PTT putting out power by using DTR/RTS setting. CAT works for FREQ. NOW i have an issue that the radio randomly shuts off and then comes back on. The off/on sequence may be quick or up to a minute or so. It appears to be when starting a series TX's.

Upgraded to 3.7.9 with Yaesu 857d. I have CAT control and PTT will light up transmitt indicator but no power is transmitted. Using 4.6.2 VARA HF and system works with Winlink VARA HF putting our power at same correct settings.
