      My K3 will be arriving back from the factory tomorrow on the UPS truck, and after I get it hooked back in, I'll be able to test the WSJT modes with both rigs -- the TS-2000 with the RIGBlaster PNP, and the K3 with direct audio interconnection and VOX for PTT. I can also try on both VHF (6 meters, FSK441) and HF (20 meters, JT65A). Got me curious now, so I should be able to generate enough data points to offer something halfway definitive about this matter.
      I do believe Russ's explanation that's it a TS-2000 "problem" (except that it doesn't appear to be really problematic), and if that's the case, I should be able to verify that. With the TS-2000, the audio is definitely "ramping up" over the course of some large fraction of a second. You can hear the ramp-up in the TX Monitor function as well as see it on the RF power output meter.

      Dave. I am only talking about VHF. I have not tried it on HF (or if I did I don't remember).  However it does not have separate PTT circuits for HF/VHF/UHF.  But all the inputs for PTT on the ACC socket control all bands.  I guess you are thinking about the separate PTT outputs for the various bands, which it does have.  And you can delay those outputs 10 or 25 milliseconds with a menu selection.  But that is not what we are talking about here.  You won't find anything about this delay in the manual because it is not supposed to exist.  And I just spent an hour going through all my old emails that even mention TS-2000 and could not find the info on it.  It has been a while since I even observed the problem, but probably because I am used to it and no longer notice.  I will try to observe it again later today and report.

      Yes, that's what I'm doing.

      However, are we talking VHF/UHF or HF here?

      The TS2000 has separate PTT circuits on ACC2 for the two different ports.

      I'll check the TS2000 manual and see if VHF/UHF has an added delay.
