Re: Microphone


Cannot find any reference to the stock microphone for KN-Q7A. only speaker mic. mentioned. I wonder what the price is.  Does it have a model name or number.?

As you see the schematic of KN-Q7A, 

it does not have any amplifier in front of a modulator NE602.
This means the mic output needs higher output level up to 1V-pp. 
Dynamic mic need an additional amplifier.
Otherwise you will see low RF output power.

The best recommendation is the original stock mic supplied by CRkits.
