[Elecraft] Share a port for KPA500

[Steve Forst]

Tnx to Andy and Bob for the feedback on this.   Yes the manual says that 
the Main / Sub radios must be connected at 115,200 bps, and while it was 
some time ago,  my testing here  seemed to prove it true.

The 890 does install 2 virtual com ports for the USB connection: 
standard and enhanced.     The standard port is used for radio control 
and audio in and out.    The enhanced port seems to have limited 
functionality.  It's a little beyond my skills and abilities to figure 
out if the  band data  is available here and if so, how to  get it to 
the KPA500.


I've gotten away with a single receiver for decades, so no big deal, or 
I can just go with the RF sensing on the amp.

Tnx again, Steve KW3A
