Hmmm this sucks. I may have to move my radios. Even if I put a bitx on my desk I will need to run coax probably 20 feet. Apartments suck for ham radio.

In general, the max spec for a USB cable is 16 feet.  I don't remember the RS232

spec length, but it would certainly depend on the driver chip. full +-12v will

certainly go farther than +5-0 TTL shortcuts.
