Hi Simon,
Unfortunately I don't have the originals; the attachments are as I found (somewhere; too long ago to remember) the on the web.
Re the schematic,? it is readable, albeit with some difficulty. IC2 appears to be strapped for direct reading, i.e no IF offset. Crystal X1 (DS(?)C7 in the pic) would be , I'm surmising, 3.455 MHz, mixed with the input from the FRG-7 to give a 0-1MHz signal which is input to the MSM5525. Can't make out the mixer part number, but appears to be a Texas Instruments part.
?
Cheers,
Steve.
