I just throw all the test equipment out the window
and see how the rigs compare when trying to copy
crappy signals in a noisy world. Tops for CW has
been, and always will be the 51J4 (or 75A4) with
the deadly combination of both mechanical AND
tunable crystal filters at your fingertips. Being able
to notch out adjacent interfering signals is a big
plus for CW. Yeah, the audio stinks, but you can
get good AM audio AND selectivity in the rough
stuff with an SP-600, which is easier by far than any
of the others to cruise around and find those strange
little signals in the first place. But, once you find that
DOD channel or pirate station, there is none better
than the R-390 to lock the channel in and leave it
there for a few weeks or months... and if you hang
a CV-591 on the ass end so much the better.

So much for all the testing and theory, the bottom
line is that different rigs serve different missions.
Regardless, you will never copy any signal of any
mode better than I can with my souped-up SP-600
and CV-157 motosyncrodetectoleviathon combo.
