Barry, The key out line on the K3 on not on a sub assembly, it is on the main RF board.
Im not sure of the relay on the SB220 but I suspect you may need to use one of those AmpKeyer interfaces that the HeathGuy or Ameritron sells just to be safe...or brew your own. It depends on the voltage requirement of the amp's relay. ------------------------- 73, Greg - AB7R Whidbey Island WA NA-065 On Thu Feb 12 7:13 , "Barry, Stephen" sent: > > > > > > > > > > > > > > > > > > >Iâm a long time builder/operator of an early K2 (s/n >377) and have considered going for the K3/10. > > > >I would use my SB220 occasionally for more power since I can >get approx. 200 watts with 12 watts in. > > > >The question I have is there a PA key line available from >the basic K3?  Or, is that circuitry on the KPA3 subassembly? > >If so, has anyone found a way to key an amp with the basic K3? > > > >I enjoy reading the list serve and the good advice from some >of the O/T submitters such as W2FPR, AC7AC and N0SS. Thanks > >guys. > > > >Iâd ask the Elecraft guys but I donât want to >bother them while theyâre cranking out K3s. > > > >73. > > > >Steve/AE2G > > > > > > > > > >
