[Elecraft] KX1 Weak Audio on 20M

[nr7f at att.net]

Folks,

I recently completed the KX1 and found a huge difference in the audio on 40M (strong) versus 20M(weak). On 20M, I always need the AF gain turned up to max, or close to it. Also, the s-meter does not function on 20M (it works on 40m). I do not think this is an issue with the headphones since 40M is fine. The receiver sensitivity on 20M 'seems' to be ok when compared to other radios in the shack, but I really need to crank the af gain up.

I've checked all solder connections, and will double check component orientation, but I do double checks on that during the build anyway. I'll check the voltages per the manual.

Any comments on likely places on the board to particularly scrutinize would be appreciated.
