[Elecraft] K3 and SPE Expert AMP

[Bob Naumann]

The SPE amp will "RF Sense" like the Acom 2000A to switch bands.

It also has provision to be driven by the Yaesu format band data from the K3
but you do not need to do that - if you don't want.

Gentelmen,
    I am considering the Expert amplifier because of instant turnon, smaller
size and reduced weight.   Does the Expert amplifier require a tie in to the
transceiver other than RF input and key out to determine which frequency to
tune to?   The ACOM 2000A does this automatically sensing the frequency from
the RF Input and there is not need for an interveing PC.   Is it the case
that the Expert amplifier needs a separate input defining the operating
frequency and band?

                        73 Doug
