Using the latest update from Elecraft and connected via the Elecraft USB/232 cable to my MacMini M1. i can get the unit recognized but when I try to see what software is on the tuner or try to upload the new file, I get a KAT500 failed to enter firmware load" error message. Any ideas?
The tuner will not hold swr... it tunes my G5RV fine but then goes out of resonance with a lot of clacking noise... if I tune and turn it off, My K3S holds resonance fine...
