That Trader sheet is, to me, clearer and more informative than the one in the R&TV Servicing books, which I had when repairing the P117, Lawrence, but even on the Trader sheet, no sensitivity figures are given. I connected my AM/FM SigGen to the FM aerial input via a 75 ohm coax. cable clipped to the dipole sockets, and found that I needed at least 80-100uv for full o/p , with the volume control at max. setting on 89, 95, & 97Mhz., when I'd expected to inject less than 10% of that. I couldn't find the limiting point at any setting of the SG's o/p either.
