Help interpreting tuner specs

I agree with Al, these look like extremely good numbers.

I find measured sensitivity numbers a bit difficult to correlate on my own test bench, and there are a few sources of possible error. First, many FM generators (like my old Sound Technology 1000A) have a 50-ohm output, so you need to use a matching network for proper calibration of the output into either a 75-ohm or a 300-ohm antenna input, and add the attenuation of this network to the signal-level dial calibration. Second, I find that there are a handful of RF-noisy devices around my bench, and sometimes don't feel like turning them all off to get a super-precise measurement. And there's the matter of the disparity of your mono vs. stereo readings - if the composite or pilot modulation level on the signal generator is off a bit, then it will show up here.

But if your tuner is indeed acheiving the performance you describe . . . it's working just fine.

Thank you for the responses. My thirty-two year old tuner recently has some modifications and an alignment by a respected broadcast engineer and circuit designer.

I have recently rekindled my interest in audio components. I was an avid hobbyist in the late 70's, early 80's. I have the Carver tx11 tuner (FM only) and used it at Marlboro College in southern Vermont, hooked it up to regular radio shack or whatever dipole antenna stretched across the wall. This tuner is amazing. My receivers of the day in this decade were Technics, JVC, Harmon Kardon, Denon. Their tuner sections were vastly inferior. I picked up Long Island fm from Marlboro, Vermot. I could differetiate between many classic rock stations close together on the dial out of Worcester, Mass(WAAF), Hartford , Ct(10.9, wccc?), New Haven Ct (WPLR), etc.
