I think you'll be happier with the 775. The R4C has relatively low dynamic
range and TOI compared to today's transceivers. Get competitive with it (ie,
contesting) and it'll fold early. But, has really, really low synthesizer
noise:)
As a point of interest, does anyone know of anyone measuring receivers with
close signal spacing, oh, for example, INSIDE the first IF crystal filters?
Seems to me, first order, that the ARRL method of using 20KHz or 50KHz
spacing has little value on 160/80. Our interferers, that is each other, are
inside the roofing filters.
At the San Diego DX Club meeting tonight Icom presented their new IC756Pro.
It has 3 IF's each with 15KHz xtal filters, leading to extensive DSP (24 bit
digitizer yielding DSP dynamic range of 144dB) at - if memory has lasted a
few hours - 32KHz in the last IF. We'll measure one (inside the xtal
filters, you can be sure) as soon as we can get hold of one.

Subject: Topband: Receiver recommendations, please!
I have more receivers than I know what to do with! I am particularly fond
of
Collins and Drake. Am thinking about having my Drake R4C modified by
Sherwood. With an Icom 775, am I going to appreciate the advantages of the
modified R4C on the TOP BAND, or should I be content with the 775????
What a great group of folks on this reflector! Thanks for your help.
