Hi I use a DCI filter on 144 and COULD NOT LIVE without it... it has
about .75dB loss but the noise floor drops about 4 to 5 dB and
eliminates nearly all the intermod I get... living within 2 miles of
Downtown Calgary, I can point my antenna right at downtown and not hear
a thing from the garbage producers... 73 de Jordan...
