[Elecraft] External linear amplifier with CW

[Fred Jensen]

I have the circuit from the Elecraft web site.  Unfortunately, my SB-220
won't really do QSK.  Any ideas on how to modify the little perf board
interface to put some (hopefully adjustable) delay in the release to
simulate semi-QSK with VOX for the amp?
