Thanks for the link. I recall seeing the wire when I checked to see if 
the IF out level mod had been done.

Re: [Elecraft] [K3] RX Attenuator value, and COR activation level.

[Brett Howard]

the ATTN is 10dB.  Not sure where the CORs activate however.  I do know
that I've hit them before though.. :)
Not sure if this helps you but I do also know that you can get to +20dBm
and as long as you have the extreme signal protection mod done to your
radio (or it was built after 9/1/2009) before the CORs are activated and
your ATT will be automatically engaged to protect the RX post amp.

[Elecraft] [K3] RX Attenuator value, and COR activation level.

[g0afh]

Hi,

What is the value of the RX attenuator in the K3?

At what level does the carrier operated relay protection operate?
