[Elecraft] Mating KPA500 ot Kenwood TS 590.

[Dick Dievendorff]

The serial connection provides the amplifier with frequency information and
is optional.  The amp will bandswitch on transmit as needed. 

You'll need the amplifier key line as well.   ALC may or may not be needed.
But the amp key line is a must, and it's not on the serial cable.

Has anyone attempted to mate the Kenwood 590 with the KPA 500?  The KPA's
owner's manual under "cabling" on page 7, suggests a RS232 9-pin cable will
successfully  connect the two units, but does not specifically state that
the RS232 is carrying ALC from the Ts 590 to the KPA 500.  I have used the
RS232 cable, am getting some drive, but cannot raise the 500's output past
50 watts outs which is what I am inputting from the Kenwood unit.
