[Elecraft] K2 smeter not showing RF Power

[Graziano Roccon]

Hello,

a friend of mine have an Elecraft K2, always working perfectly.
Yesterday, without any apparently motivation, the smeter stop to show RF Power level during transmit.

The K2 emit power without problem and the external wattmeter show the right power.
The smeter is working in RX, but not working in TX.
The K2 is mainly used in CW, so the switch button RF/ALC is not working.

Any ideas ?

Thanks a lot, graziano IW2NOY
