Looking to source the collective mind of the Fisher forum regarding what the intended MPX unit was that was to be retrofitted into this unit when MPX decoders were made available by Fisher for these units. It has a chassis cut out for the decoder (similar in size to an MPX-65), and a 9 pin socket for connection to it. For those not familiar with this unit, it's from the brass face plate era, when AM/FM stereo was the only mode of stereo broadcast available, before MPX transmissions were approved, but obviously had provisions on board for that eventuality. It includes full preamp facilities largely taken from the 400C preamp design, and is also known as the "Statesman".
Also wondering if the schematic for this unknown MPX unit -- if that unit can be determined -- is available.
I have a 202T here that I am going to install an MPX-65 unit in, but it is clearly not the originally intended decoder for this unit. It would be helpful to know how the connections from the 202T were originally intended to be made, and a schematic of the proper decoder would aid in that effort.
Finally, how in the heck did Fisher ever intend to announce reception of FM Stereo MPX broadcasts (when received) on this unit once the decoder was installed? That would appear to be a conundrum for sure, although I have an idea that might work.
Thanks in advance for any and all help provided!
