Kevin Berlen, I agree with Kevin. You will probably find the switcher is using 30 or so kHz as its operating frequency producing "hash" on the output modulating the exciter.
A good filter might fix the problem. Maybe a filter on the exciter only. Sometimes a good source for such a filter is the secondary of a low voltage, 6 to 15 VAC, transformer providing a L. Might follow it with a 1000 uf cap. If on the exciter only would require lower current capability. ron --- In [email protected], "Kevin Berlen, K9HX" <[EMAIL PROTECTED]> wrote: > > One of the systems I take care of uses a Mastr II in station configruation as > it's transmitter.
