Re: #V6 query audio level input to use for test tone alignments #v6

The electret microphone that comes with uBITX puts our approximately 45 millivolts.?
Microphone input includes a pull-up resistor for powering the mike, so you may want
a pull-down resistor that equals the current draw of the electret microphone.
