Thanks for
a) recommending the audio file. I have not used it in the past, and forgot about it.
b) the config menu. It turns out that I already have ending RSID OFF.
For personal reasons, I took several months off doing emergency comms, and am now getting back to work. First on my list is making sure all my gear is ready, and I know what I am doing.
I am testing with 2 radios.
Kenwood F6, V/UHF HT, TX, set to 0.05W...min to do the task
Kenwood V71, mobile, RX
The HT is here in the shack. The V71 antenna is on the mast.
I experimented. The attached wav file "fldigi toggle TR 20250331d.wav" is the smallest I think represents what I see. After toggle TR>T, I waited until the preamble, whatever it is, ended, then toggled TR>R.
From the time I toggle TR >R, to the HT TX light going out, is ~2.2s.
I am not nearly as concerned at this point as I was when it was 5-6s.
I am now running the same way I usually do.
Turning on TXID, with trailing RSID off, still gives me an acceptable 2 s hang on PTT. I don't see any option in fldigi that can reduce that.

Depending on the DigiMode you have tried, there may also generally be some kind of preamble / postamble being auto-appended, even without any text. For example in the Thor and classic MFSK modes, there are these little SOT / EOT characters that 'frame' the actual text, and thus, even without any TX text, they will always be transmitted, which takes a little time. Or in the Olivia family modes, the alternating lo/hi/lo/hi tone sequence will (unless deactivated on purpose) be sent prior to and after ending any transmission.
Thanks for that. I will make a note to review this. I am using BPSK125. No reason. Just grabbed it for testing.
NOW...sadly, I am back to exactly the usual config I run, and I don't see the 5+s delay to drop PTT.
HOWEVER...I now think that my "problem" was that I had TXID ON. I wasna waiting long enough for the preamble to end, and I'd toggle TR>R. Of course, fldigi would finish sending the RSID, then end. That sequence is ~5s, so I can make an argument for it. I can't duplicate the delay during normal ops /now/, so I will have to conclude this is solved, until it pops up again, if it does.
I have gone thru a number of trials, including laptop Restart, to make sure that there is no mysterious state being preserved. Still 2s of hang time on PTT. OTOH, no problem. 5s, yes, problem. 2s, no. OTOH, why does it take 2 s? Just curious.
