Re: CW Noise Pedestal

Bob McGraw - K4TAX

I suggest your find one of the remote SDR's somewhere here in the country and listen to it yourself.    Or use a second receiver suitably protected from overload and listen to it yourself.

Make sure the radio ground terminal is bonded back to the station power supply ground.  I find that the DC Neg is not adequate to accomplish this and thus allows the radio to float up from ground by the resistance in the DC negative circuit.

I have been told by at least two other stations that I have an intermittent 2.5 khz (minimum) noise pedestal on CW.   Sounds like key clicks according to them, but a bit different.   Without hearing it myself, it is difficult to describe.   The issue is intermittent, they will hear it for a while and it will then be gone.   

I am running the K3s.  I key with a bug.   I have the KPA 1500.   The noise is heard with strong signals, although I dropped to barefoot this morning and the listener said he could still tell they were there.   

At first, we thought an RFI issue.   But, if running barefoot, not likely.
