[Elecraft] K3/2K-FA int.

Roy and Friends,
     You can get a vacuum relay for the SPE 2KFA which does not clack when
running QSK.   If running QSK this is no doubt what you want to do.

     I do not operate SO2R but have my K3, P3 and Expert 2K FA amplifier
fully integrated.   The amp switches on and off with the K3, it changes
bands with the K3 band switch and at the same time switches to the
appropriate antenna and it follows me on the band.   What more could you
want.   I do not use the ALC - this per advice from people whom I respect.


      One thing though, never use the Expert 2K FA into an antenna with SWR
close to 2:1 without the antenna tuner or you will have a very broad signal
on either CW or SSB.   The solution is simple use the antenna tuner.   I
learned this when using my SteppIR trombone for 30/40 on 30 meters.

" looking for input on how well the K3 will integrate with the SPE expert
2K-FA? (etc.)"

If you operate CW QSK, be aware the SPE uses relays which clack quite 
loudly.
