KX3/KXPA100 for DX Vacation

KX3/KXPA100 combo is my main Transceiver for DX Vacation.

There are 2 ways to connect KX3 and KXPA100.

1) Using Elecraft optional adapter cables
a. DC power to each.
b. KX3 RF out to KXPA100 RF in
c. PC USB port or serial port to KXPA100 RS232(PC)
d. KXPA100 Control to KX3 ACC1 and ACC2 with optional adaper cable.

It works just like one box transceiver.
However there is a serious problem when using external logging program, Logger32 in my case.
You must always close com port at Logger32 before you turn KX3/KXPA100 ON, otherwise
KXPA100 does not start up properly. There have been no significant improvement yet.


2) Simple connections.
a. DC power to each.
b. KX3 RF out to KXPA100 RF in
c. KX3 ACC2 to KXPA100 PA Key

Each works independently. However there is no problem using external logging problem.
Power set in KX3 manually, Tune with low poer to chnage band before transmitting with full power. I get around 100W with 5W output from KX3.
