The real rub for USB serial converters is poor drivers and poor individual bios, taken together with an a Windows OS that historically does poorly with critical slow-speed hardware timing.
I've watched K3 programs and the K3 be blamed over and over on this reflector, but we are making Aptos responsible for poor code by Microsoft, hardware manufacturers, and bios writers. The only question that can really be aimed at Elecraft is whether Aptos app builders can talk to the very willing K3 *IN SPITE OF* an individual driver, bios, or OS. Every time the OS changes, and with every new motherboard, we get to start over from scratch. And blame Elecraft. Perhaps it's what they get for being the only one of those who can actually be talked to? 73, Guy.
