[Elecraft] Finding an RS-232 port on the K3

[Don Wilhelm]

Phil,

A "Y" cable on the RS-232 path will do that for you.
The real physical connection place for the "Y" cable depends on whether 
you have the P3 or not.

If you do NOT have the P3, you may not need the "Y" cable - Plug the 
cable from your Microbit to the RJ-45 to DB-9 dongle that comes with the 
KIOXB (you may need a gender changer).

If you DO have the P3. connect the "Y" cable to the "PC" DB9 on the P3 
and connect the Mircobit cable into one side of the "Y" cable, and plug 
the CBLP3Y cable that normally would connect to the P3 PC connector into 
the other side of the "Y" cable.

73,
Don W3FPR

The manufacturer says that if I connect up this output to the K3 RS-232 port, the antenna switch will automatically follow the transceiver bandswitching. That would eliminate my need for manually switching the switch on the web. (I am in the process of remoting the station using remotehams.)
