.If
you live in a big city, FM Radio transmitters are causing
intermodulation problems to your wideband scanner or frequency recorder.
FM amateur radio is also effected There is simple and effective
solution for this problem - The FM Notch Filter.
With today's technological advances, many frequency recorders look for a
signal that is at least 15dB above the background RF floor. Once it
detects that dominant signal it stops and locks on that signal and
displays the frequency.
Designed for the radio enthusiast, the EL0001 FM Notch Filter goes a
long way towards lowering your background RF causing signal's of
interest to have less RF to climb through in order to be detected by the
frequency counter or near-field receiver. This allows signals to be
captured from a greater distance than without the EL0001, helping the
frequency counter or near-field receiver do its job better. I put
on the filter and the background noise was completely eliminated and my
ability to receive was dramatically increased. The first place my ht
stopped as it was scanning the ham repeater frequencies was the 147.225
located about 80 miles east of me in Iowa. The signal was 0 s units but
perfectly clear reception was received.
I was amazed!
Other repeaters that I was able to receive with only with a rubber duck antenna
that were only 15 to 20 miles away came in crystal clear.
Description:
Each filter was produced using an internally shielded strong plastic
case to reduce weight. Fitted with some of the most quality components
like Coilcraft and Corning, the EL0001 was designed to lower your RF by
30 dB. For use with 50-Ohm impedance using standard BCN |
