New feed: BLM/WRI/NEL/N12/3N6
« on: November 14, 2013, 09:08:49 PM »
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.

Just wanted to update on the status of this feed...
Lakehurst Ground and Tower is now included, also.

Hi John and welcome!  The feed sounds fine to me...I can understand the ZNY controller just fine :)  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.

I'm glad to help. It sounds like the controllers are coming in much clearer, maybe thanks to the stub filter.
Unfortunately, BLM was just sold to someone who seems to be a pompous jerk, and wants to change it into a Teterboro-type airport. No more skydiving, no more banner planes. He wants to cater to "$50 million airplanes, not $50,000 airplanes." He says "It's hard to convince owners of $30 million jets to land at an airport when you need to worry about people falling from the sky." Sorry, just had to complain about that. Here's an article, if anyone is interested. http://wall.patch.com/groups/business-news/p/end-of-an-era-monmouth-executive-airport-sold

You're welcome  8-)

BTW, Can you get 133.5 ground side from there?

Nice setup John!  I'm actually a little surprised that you can get the ground side of both 118.975 and 125.325.  If I'm not mistaken, the transmitter sites for these two are at different locations.  But I guess the two sites are close enough together so you can hear both.  Either way, makes for great listening!

The ground side was difficult to get, but after adding the amp with FM filter, and switching over to the Pro-2006, I was finally able to get them clear enough to be understandable. Is there some way to find where the transmitters are located? From what I understand, one is in Colts Neck, which is maybe 25 miles at most from where I live.
I missed the question about 133.5, but I'll see what I get. What is that frequency for?
Anyway, I'll put 133.5 on for a bit and see what I get.

EDIT: Sounds like I'm getting ground and the aircraft. I'll see if Dave wants to add it to the list. Until I hear back, I'll leave 133.5 in the scan.
Is there a reason you wanted me to try 133.5? I notice there are already 2 feeds from the NY area with that freq. Are they missing the ground side or something?

We've been trying to get the ground side of that for over a year, it comes out of Barnegat. That is the Center frequency the arriving oceanic flights from the south/southeast check in on when they switch from HF (shortwave) to VHF, so now we would have complete coverage of Caribbean flights both departing and arriving on HF and VHF.

Now that you mention it, I think I remember Dave asking if I could get that back when I had my portable scanner set up. With the portable scanner, I couldn't get ground. It sounds like now that I have the Pro-2006 and amplifier, ground is coming in.

Hey John, yes that frequency is on other feeds. I have it on one of mine but you can't hear the ground side at all. Another guy has it on his feed but the ground side just barely breaks squelch. But your reception of 133.5 seems to be the best thus far. Many of the flights you hear on this frequency are departing/arriving JFK. These flights generally start their decent on 133.5 and get handed off to ZNY 128.3 on their way down. It's a great frequency!

I'm listening to your feed now...I can hear the beeps from your pro 2006. I know that sound well...i have a 2006 too. You must be playing around with the radio.

When they first check in 50 miles south of RESQU, ROLLE, SQUAD, ZIBUT, etc., they are around 250-280 miles out from Lakewood.

You caught me... I've been trying to fine tune the squelch. As soon as it stops on a station, I hit the scan button and turn the knob just a tiny bit. I've noticed there is a very fine line between static and the controllers dropping out.
