I finally got my feed set up (with a lot of help from Dave). It has a lot of frequencies on it, so there is always something going on.

Currently on the feed:

KBLM (Monmouth Executive Airport) CTAF (123.000)
KWRI (Mc Guire AFB) Tower (118.650)
N12 (Lakewood Airport) CTAF (122.800)
3N6 (Old Bridge Airport) CTAF 123.075)
McGuire Approach/Arrival/Clearance (124.150/120.250/120.950)
New York Center (DIXIE Sector Low) (118.975/307.800)
Sometimes you'll hear communications from Robbinsville (N87), South Jersey Rgnl (KVAY), Flying W (N14) and other local airports. Sometimes I have even picked up Pennridge (KCKZ), which is over 60 miles away.

I know the controllers are hard to understand sometimes, but it is the best I can do. I figure something is better than nothing, right?

Anyway, hope you enjoy listening, and thanks to Dave for all the help.

Hi John and welcome!  The feed sounds fine to me...I can understand the ZNY controller just fine Smiley  Thanks for the feed!

It must have something to do with the atmosphere. Like you said the controllers came in fine today. I just wish I didn't live less than a mile away from an NWS transmitter, because it bleeds into my feed sometimes. The thing that really amazes me is that sometimes I can pick up Pennridge airport, which is I believe over 60 miles away.

That NWS transmitter is on 162.45 mHz and you can knock that out with a cheap coax stub. What kind of feed line are you running?

I've got about a 80 ft run of RG-6 for the feed line. About 50 ft from antenna to amplifier, then maybe 10 ft from amplifier to ground block, then about 20 ft from ground block to scanner.

OK, I assume you are using "F" type connectors with the RG-6 since few use BNC. If your amp has BNC connections you can use a 2F x 1M BNC tee, of course, otherwise you will need to obtain one of these: http://www.mpja.com/F-type-Connector-3-Female-Tee/productinfo/19550%20RC/

What you need to do is cut a 15" length of your RG-6, leave one end open (make sure it is a clean cut with a razor, seal it with some RTV or plastic cap like often used to protect the ends of rolls of 1/4" copper tubing) and the other with your F or BNC termination. Because the station is so close, it is best to put the stub at the amplifier input. If using F tee above you will need a short jumper between the amp and the tee since (to my knowledge) nobody makes a 2F x 1M "F" tee. Put the antenna down-lead and the stub on the other two legs of the tee, and then trim the stub so that the distance from the open end of the stub to the center of the tee is 14.5"

If you cannot find a tee, you could make the equivalent to above simply by stripping down one end each of your jumper, stub and down-lead, zip-tying them together shield to shield and twisting the three center conductors together, trimming the stub to 14.5" and taping it all up.

That stub should attenuate the 162.45 signal about 15-20 dB with little to no effect upon your 120mHz signals or your UHF at 307

I may have to give that a try one of these days. Thanks for the advice.

I don't understand this... During the day, the pilots come in nice and clear on the NY Center frequencies. At night, I can only hear the controllers. No hint of any pilot communications. They seem to drop off around 11 pm. Any ideas?

You only hearing the controllers later at night is probably due to ZNY combining sectors onto one frequency when there is less traffic.  The controllers may still be simulcasting on 118.975 but the aircraft are on another frequency (probably 125.325).

The feed will be down periodically as I transfer ZNY over to a new scanner. Should be back up soon.

We now have two separate feeds - one focused on KWRI/KNEL/ZNY (118.97/125.32) and one focused on the CTAFs (KBLM/N12/3N6 + others to be listed that are within range).

Thanks to John for his help hosting!

We also have a coaxial stub filter in there now so the NOAA interference and desensitization should be mostly gone, and it seems to be.
