Hi,
One thing that you have to remember about Kenwood receivers in general is
that they have much more internal gain in both the RF and IF stages then
other receivers. I just ran a check on my ts2000 and heard atmospheric
noise on all bands. When I got to two meters, I got a little worried cause
I didn't here much antenna noise, but I forgot that aI had the aip turned on
and as soon as I engaged the extra gain, there was the antenna noise. I
have never had a more sensitive receiver, but I've never owned a 756 pro 3
either.

Hi.
I think it is a pretty convenient radio, and it depends upon the criteria
you measure it by as to whether or not it is a pretty good radio. I have
not found Tom's rejection problem here although I suspect that something is
misadjusted on his set. In terms of strong signal performance, I've found
the radio to be pretty good. But, I have found it to be noisy compared to
the other radios in the shack, so if I were looking it from the standpoint
of a quiet receiver, I cannot say that it is that good.
It is, however, convenient. You have everything right there, and there is
enough memories in the radio that you can store every repeater in your area
with all PLs and offsets and just turn the knob or key in the memory
number. In that sense the radio is excellent.
And, I love the computer programmability of that radio. Believe me, Icom
could take some lessons from Kenwood in that department.
I've toyed with the idea of picking up a second one just to see if I see
the same receiver performance issues.
