Interesting comments, Paul.

As one with severe hearing imparement, I am interested in any methods that
improve intelligibility.  I believe you have an FT-847, how do you rate the
DSP NR and DIG. FIL modes.  I use the NR=10 on AO-40 combined with RF Gain
reduction to lower passband noise fairly successfully.  However, the DIG
FIL seems to add distortion that is counterproductive for my "tranducers"
(ears).  Yet, I regularly use DIG FIL for terrestrial weak signal ssb, and
the DSP cw FIL set to 100 Hz for eme.  Go figure.

I wonder what your opinion of the FT-847 DSP modes are (assuming that is
what you use).

BTW enjoyed Symposium greatly...even the 1-1/2 hour wait in security going
home thru the airport.  Got talk with a pretty lady from Bermuda all the
time in line!
