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.
