Of course. beginning with the K2, all Elecraft rigs have a delay built
in -- that is, TX begins 8 msec or more after the amp control line is
keyed. On the K3 and later relays, the delay is adjustable. 8 msec is
enough for most amps with GOOD relays (vacuum relays), but not enough
for slower

I gave up on full QSK several years ago when I started using an active
receive antenna and a DXE phase controller. Could not put all that
stuff inside the keying loop of my Ten Tec Centurion. After the second
failure of the Centurion QSK board and associated parts, I switched to a
simple and
are burnt from hot switching.

I just had to replace one in my TL922 after about 5 years. I'm not a contester,
but sometimes I bang away in pileups for a while. I have finally taught myself
not to use QSK unless I need it. Setting the delay in the K3 to just enough to
keep the relays closed between CW elements is almost as
Pin diode rf switches are preferred today. You can even get the QSK-5 kit from
Ameritron if you can't make your own. Good to 2500 watts and infinite speed.
