Don, I use an external vacuum relay for compatibility with my old tube amplifiers. The whole system long predates the KPA1500, and I still sometimes use the tube amplifier. The system also includes small relays for switching receiving antennas and protecting the receiver. However, even withou

Scott, What do you mean by "if I get tired of all the racket"? The Elecraft gear is all electronic switching for T/R, so no relay clacking racket. That is true for ALL Elecraft gear, even the oldest K2. That may not be true for your old tube amplifiers, but the original question was about a

I know this will seem incredible to the software purists, but I have an actual mechanical "switch" in series with the PTT line. The K3 is always in QSK mode, but if I get tired of all the racket, I can just turn on the PTT. That seems to work flawlessly with the KPA1500, as well as my old tube

See CW QRO and TX DELAY in the menu.  Also the benefits and likely issues are described in the manual, page 58 and 66 as MENU items.    As to using other means to key the radio and amp and send CW, those may have their own settings as required. While I do not consider myself a high speed CW op

"It occurs if the rising edge of the keying waveform happens at the same time as the PTT line. The ONLY way around this is to delay the keying waveform slightly so it occurs after the PTT." That would seem to imply that you are not using CW VOX keying. If that is the case then wouldn't using

Try sending your callsign as TN4ZR :) I believe TX Delay 8 is technically less than 8ms however I am guessing that is not your problem since the KPA1500 is very fast. It would help if you gave a description of how you are sending CW. John KK9A N4ZR wrote: Running into what I'm sure is
