[TenTec] The QSK of QSK

PIN-diode amp might be OK, but most current QSK amps (mine included) use
vacuum relays.  I simply don't like the idea of those relays using up
their finite number of lifetime cycles every time I send one dit.  Call
it typical engineering conservatism or whatever, but that's really the
primary reason I don't use QSK with an amplifier (meaning the "hear
between the dits" type...not the PTT/foot switch type).

         Hmmmm...there's a lesson somewhere in there guys!
