You are speaking manufactured. I am speaking designed.

FR-200 single conversion analog radio ---------several decades old design
NRD-535 PLL receiver -------------------------possibly a little newer
design

More modern doesn't necessarily mean more sensitive. A Grundig FR200 is
more modern than a JRC NRD-535; which would you pick for sensitivity?
Which do you suppose Joe A would pick?

Ok, since you decided to jump on what I said ...
1. I was being facetious. The ask Joe A. reference was an inside joke
that
probably ONLY Joe would get.
2. Are you seriously trying to tell me that the design of the FR-200
is
newer than the design of the 535?

1. Okay.
2. The 535 was first sold in 1991. Yes, I believe the FR200 was designed
after that. If you know otherwise, please enlighten me.

You're talking concepts. Conceptually, a front end is a front end, so all
receivers would have to perform the same if you're right. I'm talking
actual design, as in determining the circuit topology and calculating the
component values, and I'm betting the FR200 didn't hit paper before 1995.
It's the actual circuit topology and component values used that actually
determine sensitivity. And incidentally, PLL designs date back to the
1970's; I still have clippings from the tech journals of that period.
