The thing about condenser mics.. they require a phantom power source. That makes them incompatible with direct connection to conventional radios
Adding phantom power to a balanced mic input is dirt simple, two 50uF 63v caps, two 6.8k resistors, and a 9-52v dc source. What’s more trouble is connecting a balanced mic with phantom power to the unbalanced input on nearly all radios. The simple way of using a transformer is expensive, because the only new mic transformers available today are esoteric studio grade pieces. The less simple way is to build a whole preamp.
That said, I happen to have a bag of old surplus mid-grade mic transformers (not audiophile or studio grade) such that I’d be fine mailing anybody one for experimenting.
