The quick route is to retry the firmware load. If it fails "hard", you most probably have a communications cabling problem. In all my testing of the K3 Utility (and I've tried really hard to duplicate "nightmare" scenarios) I've never been in a situation where a complete firmware reload wouldn't solve the problem. Sometimes I have been testing a marginal USB to Serial Adapter that just didn't work out, but replacing the cable with a good one has always been enough.
The K3 MCU "bootstrap" code is protected from mischief and power failures at inconvenient times. Any individual load might fail, but retrying it should cure the problem.

I have never yet had a download fail, Beta or otherwise, but, I always hold my breath until I have a working K3 again! I dread the day this does fail and I have a dumb black box on my hands. Is there a quick route out of of this nightmare scenario? I have seen written " Dont Panic" but what exactly is the recommended procedure when a new download screws your superbly honed K3? 73, Deni F5VJC Julian, G4ILO wrote: > > It has been about 3 weeks since I last switched on my K3 and when I did so > just now, VFO A said "FPF Load" and VFO B said "Pending".
