Paul -
I think the 'best buy' is the "A" version. It has more than a dozen improvements over the R-8, some
significant.
The "B" has only three 'functional' improvements(?) over the "A".
1. Selectable sideband for the AM Sync Detector
2. Faster SCAN rate.
3. 1000 memories vs 440 in "A"
There may be circuit differences, but this is the 'operational' difference. The "PROM" can be
updated for firmware improvements, but I don't even know which version I have. I suspect it might
affect the RS-232 communications, but everything on the front panel seems to do what it says! :-)
Aside from looking like a VCR instead of a communications receiver ( :-) ) it's
great!

Any significant performance or operating differences between the R-8A and R-8B?

I've never owned an SPR-4, but it would be hard to beat my R-8A. 6 kHz IF filter, Synchronous AM
detector and Passband Tuner make a pretty good receiver. A wider IF might sound better for
music, but much less resistance to QRM.

the AM Broadcast band in mind?
