I have a fax of the docs for that processor (fax is dated 1996). Because
it's a fax, a lot of the small print is illegible, but the installation instructions (one page) are readable. Basics: Pin 1 - Audio In Pin 2 - Audio Out Pin 3 - GND Pin 4 - 11 to 15VDC Adjustments: T ADJ - compression (drive into compressor) H FREQ - high-frequency EQ L FREQ - low frequency EQ LEVEL - output level to Tx Because the compressor is wideband you wouldn't want to run discriminator audio into it. The board doesn't provide PL filtering, you need to do that externally. Delay for squelch tail elimination was an optional add-on board. Alignment instructions are more or less "crank up the input gain all the way then back it off until it doesn't sound bad, then play with the EQ until it sounds how you want". No test equipment referenced in the procedure. I played with it when I first got it, wasn't impressed, YMMV. --- Jeff WN3A |

Yes, I was a little confused, but I did take a some readings with a meter to it and find that the pin out on the one connector has a normal connection that was used in that period of time but the second connector with four pins is for the audio delay board. I did not know that I was wondering what it was used for and the jumpers are probably to allow the audio to go to the board, etc. thank you KC4JNN
