[Elecraft] Different comm speeds on my KX3 and my KXPA100

[Dick Dievendorff]

Somehow the kxpa100 serial speed has been changed. Check the kxpa100 command reference to be sure, but try entering ^BRX3; followed by ^BRP3; in the KXPA utility command tester.  Then go back to the utility's port tab and click test communications. It should be 38400 at that point.

Firmware load is always done at 38400.

If your software supports 38400 I would recommend using that speed.
