The 129.4 ARINC station is right up top on that "Cumulus Granite" cloud across the river south of the airport, which I seem to recall is about a 2200' ridge littered with aluminum. I was thinking this might be in range for that new ZNY feed you just got up. I'll still help with Camelback and Elk... I just need my ARINC!

OK let me check into it.  We will likely have to split this new site into two receivers anyway.  But all depends on the transmit duty cycle of ARINC there.  If they are simulcasting all the time, like the other sites, that may be an issue to be resolved (separate receiver).

Have GRR-23, will travel. They generally do transmit from all the sites in the net simultaneously, each site having various frequency offsets, that particular site is offset +2.5kc, but the GRR has an old-fashioned crystal and can be netted, so no problem. The key over there is how good the airborne reception is, assuming we get the ground. If it is anything like what we get down at JFK, we should get enroute flights at altitude from Detroit to Boston to Baltimore since we get just about everything east of Buffalo down in Long Island now. Even if we just get the ground it's worth it to me... I'll provide a dedicated PC and run a real-time tie line to Stamford just like the one I am running from my private 129.9 receiver down on the island, then I'll feed the AGC from both of them via modulated sub-carrier and select the best airborne signal of the two and feed it out from here. Piece of cake.

So, I'm out here at my parents place running two radios off of the same antenna.  I am using a plain old cable splitter right now to split the signal to the two radios.  There seems to be only a very slight degradation in signal level due to the splitter...you can still hear the ground side on all the frequencies; 134.0 being the weakest in the bunch.  At the moment the JFK_CCC feed is running off of a split signal if anyone wants to check it out and give me their opinions.  Before I leave here I'll put it back the way it was.

Is there a reason why you would not want to use a simple cable splitter like this besides the slightly attenuated signal?

Ron-

Only reason would be if signals became so attenuated that reception was noticeably degraded.  With a 2-way that seldom happens.

BTW, Jim, I've been playing around with IGN20 reception and haven't had much luck so far.  I am using a different scanner radio, other than that nothing has changed.  But I haven't given up...

Ron


BTW...can you retweek the feed squelch to hear the "noisy" IGN20 sector?

Dave...GREAT NEWS about North Mtn... Congrats AWESOME FEED!! Love all the  LGA & EWR traffic!

BUT...how about 121.325??? That's the SFK-Hi sector for ZNY that handles all the LENDY6 Arrivals to JFK (from xmitting from N MTN)..handing off to 133.15 or 132.6...during high traffic periods... 18z-01z... Can we add that feed?

Could be the receiver quality when it's that tight...

Thx for trying...hope maybe we can get a dedicated shelton ct up sometime soon...

Hello Guys,

I'm glad you are enjoying the ZNY North Mountain feed.  Currently the antenna is a 1/4 wave mobile whip mounted outdoors, not really cut for the aircraft band, and fed to the scanner with RG-8X coax, but non the less it is working.   Today I picked up the materials needed to construct a J-Pole antenna, that will be "cut" to 129.212 (center frequency between 123.625 and 134.800), and that will be connected to the scanner with either RG-8 or LMR400 coax.  I hope this will improve the reception, especially the controller on 128.575, as he/she is just a tad bit weak for my liking.

The feed is great!  Thanks for providing this feed!  I've been listening to it all afternoon!

I have been monitoring most of the day myself.  In conjunction with the feed, I have been watching flightradar24, and surprisingly I am picking up aircraft just off PHL, over Allentown, and out as far west as Clarion.  Some are a bit week, but I  (or the antenna) can hear them.  Not bad for that whip antenna.

Imagine what that J-pole will do!  One of the antennas I'm using is actually a marine antenna mounted on the roof here on Long Island.  With that one I can hear westbound aircraft crossing into Cleveland Center and southbound and southwest bound flights passing Norfolk, Virginia or Montebello, VA...not bad I suppose...

No, not at all Ron.  That's great for your antenna.  I would be very pleased with that.  I don't believe I'm going to post the antenna change right away, just to see if anyone can notice the difference.

The j-pole should add a couple dB if matched up nicely, but unless you're on top of a hill it's all about getting above the trees. What elevation are you, and is there any way you could see if you can get the 129.4 ARINC ground station over at IPT from your location?... if so I'd be happy to ship you some equipment.  I would recommend RG-6 quad over the RG8 if you are not going with LMR-400, especially since you can easily match 75 ohm with your j-pole... and your scanner won't care. Of course if you've got a tower and can pick up 129.4, I'd give you a 60' roll of 1" Heliax complete with N terminations... better than all of them.

Not familiar with 129.4.

124.9 for ZNY low at IPT yes, but even that is tough because there is a mountain between myself and IPT.

I am on a hill, above trees, but not all of them.   I will most likely go with the LMR-400.  Oh yes, the Heliax would be great!
I want to get that RG-8X off and go with the heavier cable to reduce signal loss.

Someone made mention of the JFK arrivals.  I did monitor 121.325 for about an hour this evening on the scanner here at work, but nothing heard. 
I will keep an ear on it, and if I can get the controller good and clear may consider adding it to the scan list in the future, if there is
enough interest in it.  I have 7 frequencies going now, and I know 121.325 can get busy, although controller and aircraft are on the same freq, not
like the 132.15/124.625 pairing.  I just don't want to "clutter" up the feed.  After a day of monitoring it seems to be going pretty well.  There has
been an aircraft or controller covered, or blocked, by traffic on one of the other frequencies,  but that's to be expected when scanning 7 channels of ATC.
