I recently built a KX1 with 3080 and tuner options. Initially I had low audio but resolved by fixing a missed solder joint. With that done, It passed the initial alignment and all seemed fine. With proper ear buds the audio level is actually a bit loud for me. Unfortunately, unless I touch the circuit board near U6 the unit is deaf. Touching the board brings the unit to life and the receive is pretty good. I've resoldered everything in the area. Also checked voltages at U6. They 'seem' ok, but about 0.5 v higher than spec'd on pins 5 and 6. I've removed the tuner ( which seems to work ) and replaced with jumper and tested with same results - deaf receiver. Could it be a CAP, since I'm a pretty big capacitive load?
The build was fun and I'm learning a lot, but could really use someone to help me clear the cobwebs and work through this problem. Thanks in advance for any help you can offer as I'm anxious to play on the air. I don't want to operate the unit with my finger stuck on the circuit board, I might give people the wrong impression of ham radio operators. 73 de KC2MJT Nate Houck _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
