[Icom] Re: IC-751A vs. IC-765

[Jordan]

The IC-751A is/was very well known for having an excellent dynamic range, being
extremely sensitive, and having outstanding specs for IMD, both in-close and
wide band.... I've owned many many many rigs, and it ranks right up there among
the top 5 as far a receiver performance is concerned... if the 751-A can't hear
it, there's probably nothing that will, at least, not within the price range, or
even an octave above it...73 de Jordan....
