I have been using MixW for years with this setup and have always had trouble with CW.
I have two homebrew interfaces hooked to the 850 and PC. One is an RS232/TTL converter for rig control and frequency tracking. It is on COM1 on the PC. COM2 goes to a 3-transistor switch for CW keying, PTT and FSK keying lines. If I am using MixW in BPSK mode, in MixW, COM1 RTS is set to "always on" to track the radios frequency. COM2 is set for "ptt (RTS)" to key the 850. On CW I have to set COM1 to "ptt (RTS)" or the radio will not key. As soon as I switch the COM1 RTS setting from "always on" to "PTT" the CW will key properly but the software no longer tracks the frequency and all log entries have to be edited by hand. Is there any way to have COM2 do my CW keying? I have tried every possible combination with the COM port settings and no luck. If I set COM2 for PTT (RTS) and CW (DTR) the 850 will momentarily key but then unkeys although I can still here the CW in the sidetone monitor. HELP PLEASE!! Max VE3TMT
