thanks everyone who responded. the phrase "nebulous improvement" that Joe
used to describe the benefit the modifications would have seems entirely
accurate. Another correspondent in a private message described the
noticeable benefit accruing only to those with "golden ears." Often we fail
to recognize the simplest solutions, which is what I did here. An external
speaker did not occur to me until I read the replies. This is an easy and
inexpensive improvement that will offer quite tangible results. This is
certainly something I will do. I am also exploring the AM filter issue and
will likely replace it. Thanks for all the help and sharing of experiences.
As one of the posters said "if it ain't broke, don't fix it." applies here
too.

My Icom R71A audio improved immensely by the use of one of the add-on
computer speakers that has really great low frequency response. That
coupled with the outboard JPS NIR-10 Noise/Interference Reduction unit
makes it a real joy to operate.

The speaker is a about a 3x5 inches with a heavy magnet and a tuned port
at the bottom for some reason. I an no audiophile for sure. It just
sounds great.

I will appreciate any insights that can be offered on these modifications
in
helping me decide if it is worth it to add them.
