Jerry, I also would encourage you to look at the KRC2 for your solution. It will provide BCD band output as well as individual outputs for each band.  Use whatever is compatible with you amp. The K2 on its own does not provide external band data except by decoding the propriety AUXBUS data.

I would suggest that the Elecraft KRC2 would provide the information quite well. It was designed for use with the K2, receiving band data and providing the ability to select bands with both high and low drive outputs. It also outputs the BCD data on four terminals. Take a look at the ELecraft

Hi Jerry, There is no simple access to band data in the K2 unless you want to reverse engineer the AUXBUS protocol. Depending on how your homebrew amp selects its lowpass filter options, you may be able to pick up the relay control signals for the K2's bandpass and lowpass filter banks and use

Hello All, I'm interested in putting my K2 on the air with my homebrew LDMOS linear. My amp doesn't have a bandswitch - it gets Yaesu band data. Follows the transceiver from band to band like a puppy. I like it that way, because it's always on the right band, and I don't fry the LDMOS.

Hi Allan, In your original post you said your K2 seemed somewhat 'deaf.' Does that mean you hear no signals at all on any band, no signals on one or two bands, or just weak audio with antenna or signal generator input? Since your K2 has the K160RX option, I would check that the RX antenna is
