Jeff,
I am not sure why you want to locate the W2 directional coupler between
the K3 and the KPA500, but that is your choice.
As far as the high power coupler, what you wish to monitor will dictate
where you place the coupler. If you place it between the KAT500 and the
antenna, you would

Hi Vic,
If I remember correctly, there was a discussion here a few months ago,
(which I can not locate in the archives for some reason), dealing with
this behavior... I think it had something to do with telling the K3 to

PTT
I remember that discussion. I am pretty sure it was about a different
problem. Anyway I am using VOX (er, QSK) with no connection to PTT.

I have the same problem and it does occur in TEST mode so it isn't RF.
It is also a problem of long standing, not related to any recent

I have just tested it with and without a logging program running. It
happens either way.
The way I test it it to turn QSK and TX TEST on and send a series of
groups of V's with the internal keyer at 25 wpm: VVV VVV VVV etc. It
seems to happen from once every three groups to once in 8 or so.

It only happens here when the logging program (N1MM+) is active,

some kind of data collision which is being resolved by timeouts.

I hadn't noticed any hangups while testing with an external keyer using
