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

[Bert Garcia N8NN]

The CAT and PTT are on different COM ports, per the installation instructions for the microKEYER II when using WSTJ-X.  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.

Thus, I suspect the issue is associated with the WSRJ-X software as the same issue occurs with various transceivers in multiple locations.

Bert and Gary,

Have you looked for a computer problem?  Such as having both PTT via command and via an RS-232 signal line?  Do you have both VOX on and another means of keying the transceiver?
