Re: [Elecraft] K-2 Transmitted signal distorted (Hum)

Thanks for all the replies! Not a power supply problem. Does exactly the same thing when on battery backup. Nothing new in the operating position to create a problem. RFC15 is *NOT* open. There is 5 volts on both sides of it. Don Wilhelm wrote: One thing you may want to check is RFC15

Re: [Elecraft] K-2 Transmitted signal distorted (Hum)

Greg, You must check RFC15 with n ohmmeter to determine if it is open or not. Even if it is open, there will be 5 volts on both sides of RFC15. 73, Don W3FPR Greg Storms wrote: Thanks for all the replies! Not a power supply problem. Does exactly the same thing when on battery backup.

[Elecraft] K-2 Transmitted signal distorted (Hum)

I have just started experiencing a tremendous distortion on my transmitted signal (K-2). It was first noticed by a SSB contact. He said my transmission was strong but nearly unreadable. I duplicated it at low and high power on a separate receiver. It occurs on both SSB and CW. This happened

Re: [Elecraft] K-2 Transmitted signal distorted (Hum)

Greg, It could be any number of things from having an AC transformer located too close to the K2 (especially on the left side - did you re-arrange the operating position?) to a bad solder connection somewhere. We need more detail to even get started. One thing you may want to check is RFC15
