The more recent NRD series of receivers were not noted for good
sounding audio. They had very good ergonomics and were very "pretty",
however. The R75 is probably about the best deal around nowadays,
particularly if you do the AGC/sync mod to make the sync detector work
properly. I was sorry I sold mine.

I have the Kiwa mods for the agc/sync and the audio upgrade too. The R-75
is unquestionably the best value for dollar table top that there is. The
only thing that it is missing is ssb selectable sync. At times I prefer to
use my Sony 7600gr through the PC speakers over the R-75 for SW broadcast
when there is QRM coming from an adjacent signal. That ssb selectable am
sync can make all the difference at times. I keep wishing that ICOM would
make an R-75A with a ssb selectable sync that works. Other then that, it is
a great radio. It is supreme for all ssb uses. DX'ing using the R-75 with
ECSS tuning in ssb is the most effective way that I have come up with for
dealing with hard signals. The twin pbt is the cat's ass. Using this
NRD-545 with its DSP for DX'ing in AM is not as effective as using the R-75
in ssb for DX'ing. I have the optional DSP module in the R-75 and I've
found that using the nb on a setting from 1 to 3 is a big help at times.
Not true DSP, but it helps. Bottom line, I cant see paying all that money
for the NRD-545. It isnt a better performer then the R-75.

Frank,

Do you think the sync' mod really makes it work properly or just
acceptably?

Good question, but based on my experiences with the DSB sync detectors
in the Drake R8 and the Lowe HF-225, I would have to say that the
modified R-75 worked as well as the 225 and definitely maintained
better lock on signal fades than the R8. So, I would have to say that
it worked properly, at least on the one I modified. The best sync
detectors I've seen are in the Drake SW2 and the Lowe HF-150. They are
SSB selectable.

I returned the R8 that I bought from Grove in 1991 for $950 because the
sync' was so finicky. I wait about seven years for the R8B, which has a
superb sync' detector. I also have an SW8 with selectable sync'. It
works great.
