I bellowed all of the solder joints and it works now. I did get info 80 error code when I switched the band to 80m. I turned the power off and the code went away. I cannot get the error code to repeat. I followed the troubleshooting procedures in the book and everything looks good. Do you think i should check anything else?

There are several possibilities. First is that you just may not be hearing the 4 MHz oscillator. Even if the 4 MHz oscillator does not start, you will still see the K2 try to power on - yes, it will not be successful, but at least you should detect a "blink". Substitution is the quickest way to localize a problem. Do you have any other K2 owners around? If so, perhaps they would let you temporarily swap their Control Board for theirs. If it works, you know that the problem is on your Control Board. Next step would be to put their firmware chip on your Control Board. If yours works, then you will know that the firmware chip has been damaged. Use good anti-static measures when changing out a firmware chip, they can be damaged by mishandling. I would rather see you checking the components in you 4 MHz crystal area, C21, C22 and X2 for proper values and good soldering. While anything can be faulty, the chance that the crystal is bad is small. 73, Don W3FPR dogbulter wrote: > Since I cannot detect the 4mhz oscillator at the MCU (U6), I was wondering if > I could use an external clock to make sure everything else is working.
