[Elecraft] FW: [N1MM] FSK problems on K3 radio

[Richard Ferch]

Tom,

I have had this "stuck in transmit" happen to me a number of times, most 
recently just yesterday when I was playing with various settings while 
checking out a configuration problem for another N1MM user. I have also 
encountered several similar cases on user groups, not only for N1MM 
Logger but also for the DXLabs software suite.

The common thread in all of these problem reports appears to be that 
when the "stuck in transmit" problem happened, there were two methods of 
PTT control being used at once. For example, a user may have been using 
PTT via software command over the serial link (TX; and RX; commands) in 
parallel with a hardware PTT connection (either to the K3's PTT IN jack, 
to the AUX connector, or using RTS on the RS232 port). Whenever this 
problem has happened to me, I have always found that I had two parallel 
PTT methods configured.

In every such case that I am aware of, disabling all but one of the PTT 
methods has always solved the problem. It looks to me as if you have a 
hardware PTT connection from DTR on COM1 - at least, that is how you 
have EXTFSK configured. If so, that is the only PTT method you need. In 
the N1MM Configurer for COM3, is the "Radio PTT via command" check box 
checked? If so, try unchecking it to see if that solves the problem.
