[Elecraft] WSJT-X K3/K3s hanging as Tx

[tomb18]

What Joe, eluded earlier is actually true in some cases. Software can bombard the serial port with so many commands, without  listening  to a response and then issue the cat command. The problem there is the radio is processing all the other commands and the PTT is delayed. 
In wsjt if you are using it alone with the native cat support and a k3, the data rate is very low, not like  something like n1mm. There you can use the cat commands for Ptt without any issues. On the other hand, just turning the computer on can toggle the dtr and thus the radio can go into transmit. There it requires disabling advanced parameters in the serial port drivers, to turn off interrogation of ports. 73

Bert and all,

Use software PTT in the applications while W4TV figures out what is 
going on with the MicorHam  gear.
Are all those having a similar problem using MicroHam something? or does 
it occur with other interfaces.

And it's not a stray RF problem as I have all the equipment bonded together, ferrite cores on the audio and control lines, a line isolator in the feedline where it enters the house, and line isolators between the rig and amp and between the amp and antenna tuner.  The lockup happens when running only 30 watts with FT8.  It never happens when running a KW on many other modes.  I run RTTY, PSK and other digital modes with no problems.
