[Elecraft] K2 - low power/reception on 80m

[Philippe]

Hi, 

I bought an used K2/100 with an issue on 80m: 

- RF is low (less than 1 watt) even when PWR set to 100W  

- reception sensibility is low as well, I need to switch the PRE to hear
something on the band. 

- all other bands are doing fine (good sensibility, 100W+) 

I first though about the band filter but I didn't success to get any RF
increase when re-tuning L3/L4. 

Do you have an idea where I can start? 

Thanks
