[Elecraft] KXPA100 RS-232 problem

[Thomas Beltran]

Thanks Dick, John and Don - I plugged the Loop control directly to the KX3,
and tried the different baud rates - the control only works on 4800.  In
other reading, it seems that when the amp is on, everything defaults to
38400, so that is probably why the control box can not communicate.  Perhaps
by way of the utility codes, I can change the baud rate of the amp.  Thank
you for helping me get closer to the solution.  Tom

Tom,

If it were not for the addition of your loop control box, you would set both
the KXPA100 and the KX3 to the 38.4 rate.
But take a look at the baud rate requirements for your loop control box. 
  If it will handle 38.4k, then all is well, but if it requires a lesser
baud rate, set both the KX3 and the KXPA100 to that baud rate.
