RE: RE:Band stop filter AM/FM overload

High Frequency Data Link.Its the hf version of ACARS which most comerticial
aircraft use for data messages and reporting.
PCHFDL is the program to use.

I agree with Skip, Its always good to ensure that your antennas are set up
right especially the grounding. I am definitely not a electrical engineer
but I found through reading, asking questions and experimenting some that I
had faulty grounding through my coaxes a few years ago and corrected the
situation which gave me lower noise levels plus better signal. I became
really good at installing coax connectors, which can be a problem. A few
months ago I purchased a MFJ-969 tuner for the hf side and was able to tune
away from a lot of unwanted garbage without harming my signals. I found this
extremely effective when receiving HFDL signals on hf.

AM and FM are two different animals (bands, actually). I live less than 2
miles from WBZ's 50KW
Antenna..(1030 KHz). Filtering depends more on what you're listening to.
Your AM station isn't likely
to bother your satellite photos, and your local pager transmitter isn't
going to harm your shortwave
Listening.  ALL filters cut the signal you are listening to.  They just cut
the stuff outside to the pass band
Better. Also, a good ground helps. An outside ground rod is a good ground
for the end of you coax cable.
 That way the shield doesn't act as an antenna.
   Next, what 'band' do you plan to spend your time with?

I am wondering if anyone has any idea's of constructing a am/fm band stop
filter for the pcr1000. I live close to some towers
here in Tucson AZ and getting swamped. I can have just a 4 ft section of
coax and still get a signal, so anyone with ideas
would help.
