I double checked all of the connectors and compared them with the manual. They are Installed correctly. I do have an o-scope and I cannot get the 4 mhz signal around x2. I tried adjusting c22 and it did not help. I also checked all the components around x2.

If it is backwards, the symptoms you report will be present along with the 5 volt regulator getting warm (hot if you leave it that way enough time). U6 usually survives that abuse. 73, Don W3FPR dogbulter wrote: > I am having an issue powering the K2 on. I am on page 43 of the K2 manual.
