[Elecraft] K3 and SPE Expert AMP

[Kjeld Holm]

Hi gentlemen,

Ideally you should pass band data from K3 to the Expert amplifier. But if
you do not the amplifier will still be able to sense the transmit frequency
- but you have to transmit (just a dot or two). Just changing frequency at
the K3 will not change the Expert amplifier to the correct band.

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?
