RM KL503

[Blue Ox2]

Well, I seem to have developed a buzz. The 503 is hooked through the Comm port on my MFJ 1703 Antenna/Transmitter Switch to 4 different radios.

I use it mainly for the Cobra 142GTL that has been direct injected and have developed a low buzz on level one but a more pronounced, loud buzz on level two and above.

Any ideas about this development would be appreciated.

I have no clue on why it is buzzing unless the power supply is going south. Did you try taking it out of line on the switch? Could be the contacts in the switch are getting dirty.

Thanks Greg.

We'll try that.

Hi Greg,

Bein' the dummy I be, are you referring to the power supply in the amp,
or the Megawatt 400-12 I have running it?
