Hi All, To save me bothering Gary again (he's busy enough as it is) is there anyone out there who can explain how the RIT or XIT offset is applied to the K2. I can see it originates from the Front Panel and the voltage from the pot goes to U3 pin 16, but thats where I lose it. Any ideas are most welcome :-) Thanks Trev G3ZYY (Still working on his Tx/Rx difference) -- Trevor Day
