[Icom] Rig advice

Johnny,

I echo Larry's remarks except to add that in my case I have kept my IC-765
even though I have since purchased the original PRO and now a PRO2. The 765
is a classic and built like a battleship. I recommend that if possible you
hang onto your 765 and still get the PRO2. It is a much superior radio to
the 765, but the 765 is still superior to a good many others.

I use the JPS NIR-12 outboard audio DSP unit with the 765 and with my
Elecraft K2. It is a big help but nowhere nearly as effective as the
internal IF DSP of the PRO2.

Hi Larry,

Just my personal comments.  IC756 (original) has already been better than
IC-765.  Therefore, applying the same logic, IC756 proII should be better.
Please visit Adam AB4OJ's web page at www.qsl.net/icom.  You would get an
answer.

While external AF DSP unit is good (I use a Clear Speech Unit with my
IC756), it cannot be compared with IF DSP where you have a whole range IF
filter selection.  The IF DSP filter of IC756 pro II is within AGC loop so
that pumping effect by surrounding big guns has been much reduced.  With
advancement of electronic technology, the drawbacks previously facing IF DSP
filters have been gradually overcome.

It would be a big jump in performance if you replace your IC765 with IC756
proII.  Clearly, I do not say that your IC765 is of no good but the IC756
family is better.

I'd appreciate some advice from IC-765 & IC-756ProII users. I currently
have an IC-765 which is in near to perfect condition.

Should I...
1) Hang onto the 765 perhaps adding a good audio DSP unit or,
2) Upgrade to the 756.

Thanks
