I have always like 'the "space age" look of this mike and would like to know if it can be adapted for ham use. I cant find any technical info on it, but I seem to remember that it had a preamp circuit built into it - similar to the Turner +2. I installed many of these in the late 70's/early 80's when I was a Motorola tech. Also, any thoughts on its companion, the HMN1001 Hand Mike. These hand mikes were durable - had to be - they were the default mike in police, fire,etc. mobile installs and took much abuse.
