I recently built a KX1 and it went together smoothly with no real problems. I made a few QSO's and it seemed to work just fine.
I turned it on today and it is acting up on me. I was on battery power and switched to a power supply to see if that helped, but no luck.
It is a basic 20M/40M unit with no ATU in it yet. (It is sitting here half built).
The symptoms are that when I turn it on I get a loud hum/buzz in the earphones for about 2 seconds and then it goes to a quiet hum/buzz. This happens whether or not there is an antenna attached or not.
Also..on the LED it seems to be showing the signal strength but I cannot get the LED to change. I can press the various buttons and the VFO knob and get no change in response. The hum/buzz continues and there is no change in the LCD.
I am going to take a good look at the solder joints and see if there is anything obvious. Then I will check them again.
While I go through that process, does anyone have pointers on where to concentrate the efforts? The troubleshooting guide in the back seems to depend heavily on two digit codes on the LED...but I don't get one of those.
Any and all help appreciated!!
