Being able to listen to the A.M. / F.M. / Shortwave bands in one radio that
you can hold in your hand and uses AA standard  batteries can be very
useful. Individual requirements for what someone wants will determine
the  category of product they get. If the requirement is
hand held using standard batteries
... well, there just isn't anything else out there to compare to a
PL660. Fortunately the current production of PL660 products
do not have a lot of issues. I suspect they pay attention to
customer feedback and make changes in production as they
can fit it in. Current radio has great A.M. quality and with great
sensitivity,and audio is quality is good.

older PL660 can be improved
