Re: uBitx just started transmitting a loud hum #ubitx-help

I had the bitx40 that quit transmitting. The electret mic failed. I didn't get the hum just silence. The replacement mic has given the radio increased power, about 10 watts. 

I wondered if humidity from my breath caused the failure. I like the idea of a voltage spike though. Seems more likely.  Am wondering if I should put a choke between voltage source and load resistor.
