All,
Thank you for your replies.? However, I need wideband analog input, not the typical/normal 250-3000 Hz audio.? The wideband audio is from darn near DC to 5+ kHz.
I was hoping the "Aux TX Audio"? on pin 5 of the 50 pin connector would be it, but it appears to only be 250-3000 Hz, or less.
Unfortunately I only have the service manual in pdf form.? Trying to find what I'm looking for in that is giving me a krik in my neck and my peepers are becoming crossed.?
If you look at the exciter schematic you will see pin-78 of P/O P-102 .? It's called, "VCO AUDIO" and goes into the 6 kHz splatter filter circuitry and then directly to the "Varactor modulator," CR3250.? I may have to break down and access this by modifying the back plane board.? Being lazy, I was hoping for something simple.
