[Elecraft] KXPA100 RS-232 problem

[John Pitz]

It is likely a RS232 speed issue like Dick Dievendorff said.  Something
else you may want to do is change the KX3 baud rate to match the
KXPA100.  The KXPA100 doesn't care what the baud rate of the KX3 is and
will auto detect it.  This way you will be able to seamlessly use the
KX3 by itself if for some reason you don't want or need the amp.
