SRA-198 microphone frequency response

Looks like it's pretty useless on most radios from a Fidelity perspective.

 

You saw the flat frequency response with your own eyes when he tried to say the letter S on the stock unmodified radio.
After altering the frequency response of the radio only then did the microphone become useful.

 

He doesn't tune the microphone to the radio.
In fact the sole purpose of that video is to show people that unless you have one of his radios that microphone is totally useless.
Have you ever noticed someone on the radio where it is hard to tell the difference between the letter S and the letter F?

 

There is one aftermarket microphone actually there are two aftermarket microphones one of which is no longer manufactured that provide the frequency response he is looking for. The first microphone he recommended back in the day was the original Telex Road King 56. My Electro Voice 602 T microphone meets his rigorous standards.
Not all microphones are created equal. That's what he's trying to show you.

 

I guess the other point of that video is to demonstrate why that microphone will sound good on Mark's radios but sound crappy on other technicians radios.

 

Back in the old days you could buy a Cobra 29 and a Road King 56 at a truck-stop and hook it all up and five minutes later you'd be Broadcasting with great fidelity and exceptional intelligibility.
With all the microphone companies going out of business in the United States our microphone options are shrinking

 

It's not Marks fault that Telex no longer manufactures the road king 56.

 

As long as it's plugged into one of Mark's radios it will work just great. Don't expect it to sound as nice on someone else's radio.
