BS! Many rigs have race conditions in their processors. *NEVER* use
software PTT and stick to hardware (RTS) switching only - particularly
if you have the need for external sequencers and audio switching.
If you have a problem with hanging PTT with hardware switching, fix the
common mode RFI issues in your shack! If you don't fix them now, they
will bite you later (and somewhere you don't expect).

Using hardware PTT using Dtr or RTS is technically fine but many software
packages will default to having them on with the consequence that the
transmitter is in transmit mode if PTT is set to dtr. It becomes more and more
complicated with more software hooked up. I have yet to see any software that
cannot be used with software cat based PTT. It gets rid of most issues. As I
said it is fine, but it takes more effort to make sure everything is set
correctly. It also is possible that you will have to go into the driver
advanced options for the serial port and turn off interrogation at start and
other possible values. Play it safe, just use software Ptt for everything. 73

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

I've been using WSJT-X since it was first introduced several years ago,
and I've never had this problem. I've always used VOX to put the rig in
TX mode, as I do with SSB and all digital modes. I've often run with a
power amp that uses a vacuum relay for T/R switching, and there's
sufficient delay within the K3 and K3s for the amp's T/R relay to switch.
