Paul, The "ERR KEY" message indicates that you have CONFIG:PTT-KEY set to something other than OFF-OFF and that either the RTS or the DTR line was set "On" at the time you restarted.
This may be related to the intermittent TX problem: I find that when using a USB-to-serial adapter for radio control, making changes to other USB devices sometimes results in disturbances on these control lines, and if I have PTT set to use RTS, I see the radio toggling between RX and TX for a few moments at these times. One solution to that is to turn CONFIG:PTT-KEY to OFF-OFF and use PTT via software command instead. Another is to do PTT and CW (and FSK) keying on a different serial port from the one you are using for radio control. 73, Rich VE3KI NF8J wrote: > The last couple of days, on 20 meters, 14.070 in data mode for psk31, > the TX led lights up intermittently, and the audio make clicking > sounds.
