[Elecraft] K2 question

[Dave Sublette]

Is the KUSB cable compatible with the K2?  Should have asked this before I
bought the cable.  My K2 has worked with a serial port adapter from Keyspan
for several years and with a variety of logging programs.

I had to ditch the keyspan because BiG Sur doesn't have a driver and
Keyspan doesn't have a compatible driver for Big Sur

So I went with the KUSB.  When I connect it, the K2 does strange things.
Power control turned all the way down results in a nice 10 watt output  and
normal operation.  When Power control is turned up I get a HiCurr and LoPWR
error and the display only shows power, not frequency.

Any thoughts?

Thanks and 73,

Dave, K4TO
