This is a Heil Cable. You can see the 'Heil' name/logo printed on the 4 pin plug. I got it from a friend that got it from Heil.
SO, they did make them.
AS far as not telling the whole story, that isn't the case. There will be differences from radio model to radio model and mode to mode in terms of freq response. That is true. But it isn't so great that you cannot make changes with some EQing if you want to use it on SSB, AM, and FM. Doesn't mean that you won't favor the pro gear over the traditional mics just the same - every time.
Best to keep the modulation at/below 100%.
Otherwise, all you are doing is adding distortion - the very thing you are trying to avoid!
The BEST way to monitor the sound if you are going to use an EQ on the mic - is to use another radio as a monitor. Just put a dummy load on it and turn the RF Gain down real low. Hook it up to a 3 way external speaker (or quality headphones) and have at it until you get it to where you like it and on-air comments from a local radio op can verify the job done right. That's it.
ALL radios will benefit using pro audio gear over either an Astatic D-104 or Turner+3. Unless you would like to dispute the specs between the audio gear and CB power mics. BTW - there is no contest. A world of difference between the distortion, sensitivity, and frequency response characteristics between these two methods of getting the job done.
The D-104 and Turner+3 are fine mics.
But they just cannot compete with a cleaner preamp and a real pro mic element.
