[Elecraft] KAT500 lost serial comms - try factory defaults?

Hi all, I’ve used my KAT500 with pleasure for many years, but recently a problem has arisen: I’ve lost the serial communication feature. I’ve already swapped the KXUSB cable with another one (home-brew) so I’m pretty sure it’s not the KXUSB that’s gone kaput. And the PC is doing USB comms fine

Re: [Elecraft] [K3] K3 Off Grid

My K3, on receive, with the KAT500 in-line, the P3, and my massive 70A Astron p.s. powering the K3, drew about 20A DC. Putting the K3 in transmit mode, with just under 12W drive (so as not to kick in the 100w amp) required about 30A DC. Boosting the output to 50W drew about 70A DC.
