I'm not familiar with CAN-bus. How can I easily implement this in my setup? End result is I want two way CAT control -- amp gets band/frequency data from the radio, KPA-1500 remote app gets SWR and power from the amp to display on the PC and control the power switch and standby/operate from the remote app.

A quick Google confirms that for a baud rate of 250K, it will work up to 820 feet. - Jerry KF6VB > > -----Original Message----- > From: elecraft-boun...@mailman.qth.net > <elecraft-boun...@mailman.qth.net> On Behalf Of Jack Brindle via > Elecraft > Sent: Thursday, June 2, 2022 12:30 PM > To: Elecraft Reflector Reflector <elecraft@mailman.qth.net> > Subject: Re: [Elecraft] Relocating my KPA-1500 - need cable > > Using a network connection would be a very good idea.
