I have a Grundig S350 in which I upgraded the wide selectivity filter which
is quite poor. it now has excellent SWL selectivity with a 1.5 shape factor
and is a great little portable. after the mod, drift is almost completely
gone !!!

a recent review on radiointel.com rated this a top MW performer at a low
price !!!!

my price is $95 plus a few for shipping. and it includes the box etc !!!

I think this is a great price due to the significant upgrade in performance
