Tom: Likely the same problem as reported on the Traveler Headset. Powered Microphones seem to have the problem. If you unplug your mike, the problem will go away.
The Heil "Traveler" headset uses a powered microphone, that picks up noise through the microphone power. All other Heil mikes are pure dynamic mikes without an amplifier, and sound great on the FLEX-1500. (Just don't put a Heil Traveler adapter on any other Heil mike, or the noise will come back.) The Yaesu MH-31 mike without the touchtone pad is reported to work quite well. I suspect the "TouchTone" oscillator in your mike is taking power up the microphone hot side conductor and picking up some power supply noise. --- Graham / KE9H == On Thu, Jul 22, 2010 at 8:45 PM, Tom Azlin N4ZPT <[email protected]> wrote: > Hi. > > I have my new Flex1500 up and working.
