[Elecraft] K2 Locked up after 160m module install

[hamblen9 at optonline.net]

GM,

I built up and installed the 160m module. Powered on the K2 and it locked up. No error messages on power on but no buttons will have any effect. VFO works but that's all.

Removed 160m and began troubleshooting. The only observable issue: Resistance between pin 1 and pin 10 on the 160m module is open. Still troubleshooting this simple module circuit.

Meanwhile I reinstalled the W1 jumper and repowered the K2….it's still locked up. I've read Don Wilhelms injunctions against "not doing a MCU reset" but what are my other choices?

Thanks, Guy
