[Elecraft] Insensitive Rx and very low Tx output on my K2 Serial No 06574

Hi Don
Your Ref 4A32BAEF.103 at embarqmail.com.
Many thanks for your speedy response to my earlier query.  I have been
away for a time and have changed my ISP. The problem is that twenty meters
does not work, the Rx is insensitive requiring very strong signals for
them to be heard.  The Tx has a very low output with error message LoP
being displayed. I would restate that that 30 meters functions normally as
does 160 meters. The Rant on 20 meters is off and I do not have the KPA
100 installed. I have changed antennas without any effect.
Looking at the circuit diagram it is difficult to see what is only  used
on twenty meters other than the VCO frequency or possibly some weird
constructors (me)error. I would welcome any further assistance.

Many thanks
