Hi Ian,

Do you have access to a RF signal generator, or can you build the crystal oscillator source shown in the troubleshooting section of the K2 manual?  I've found the receiver signal tracing protocol described there to be helpful.  The RF probe supplied with the K2 is useful if you have a good high input resistance DMM.  There are several possible sources of unintended signal attenuation along the path from antenna connector to audio output, so more experiments will be required to deduce the section(s) in which problems may exist.

You mentioned using an ATU with your longwire antenna -- if it's the KAT2 inside the K2, did you check to be sure that your antenna port selection in the menu is for the connector to which the antenna is actually connected?

Do you notice a difference in audio signal levels on different bands or is the audio output uniformly low on all bands?
