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

[Rick Bates, NK7I]

Frank,

I would start with a complete power removal (not just off) to the KAT500 
and the computer (unplugged from power).  Then go have a cuppa.  When 
you get back, plug the power in and restart it and test.

I have found that some devices (more in the USB realm) occasionally 
'stick' when exposed to RF and that a long power removal is the only 
cure.  If it's a frequent event, you have an RFI issue to deal with 
(better grounding and bonding is the first place to start for that).

GL,
Rick NK7I

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 (e.g. the USB interfaces to my K3), so I guess it’s not the PC or the USB port either.
