It's always tough when you've got a bunch or frequencies where you only get the airborne side. If I am not mistaken, Ron feeds one from his pop's out east and the other from home in Nassau. The gem in his collection is 134.0, where he can get the ground from his dad's, and if it were me I think I would at the very least have a dedicated radio for that one, run the feed out there in stereo, put that freq on one side and the kettle of fish on the other. At least that way you could get full QSO for one of these many channels, in fact if I had to choose between streaming either a dozen one-sided channels of mostly very brief acknowledgements of instructions or a full air/ground channel that occasionally is dead for hours at a time, I would still choose the latter. Even if you didn't want to run stereo, I would still use two radios, one scanning and the other on 134, and brew up a simple audio priority switch to pad down (not fully mute) the scanning radio whenever the squelch on the fixed radio is opened.

Even without an active device you can make a simple three-way mixer with a handful of resistors and a small chunk of perf-board that will give left, right and center audio with a stereo feed, which is what I use on the HF feed. We're not talking about hard left and right, more like 45 degrees either side, which makes things less disorienting. Using three HF receivers I feed 5550 left, 6577 right 24/7 and 8846 from 9AM to 8PM in the center, and it is rare that two frequencies are in use at the same time, let alone all three, and only when they are switching over as the bands go up and down.

Even with a mono, single channel feed using blended audio, if you group frequencies between two or three radios such that all the channels associated with certain arrivals or departures are allocated to one receiver, with different receivers becoming more active at different times, you will still be far better off than with a single radio scanning a dozen channels.

Of course this is all IMHO

Hey ID, how's it going?

The feed out at my parents place in Ridge is the one with 134.0, 135.8, 132.3 and 124.525.  You can hear both sides of the conversation on all of these frequencies.  132.3 is the odd one...it is only used occasionally.  So if this feed were split up, I would probably put 134.0 and 132.3 on one and 135.8 and 124.525 on the other.  The only issue is the antenna.  I can't put up a second antenna so the signal would have to be split.  It would be nice if 134.0 had it's very own feed but then at the same time 135.8 should also have its own feed IMO Smiley

So, what about the other feeds here at home?  I fully agree that there's a lot happening on both feeds.  So, hypothetically speaking, if they were to be split up, what do you guys think of this arrangement:

#1
132.525, 126.875, 125.45, 125.325, 125.575

#2
120.75, 121.375, 120.975, 133.125, 118.975

#3
128.3, 133.5, 127.7

#4
134.6, 134.325, 121.025, 133.975

This takes into account as much as possible the routes that flights take through each sector.  #1 for example is mostly northbound overflights and descending flights into KLGA and KEWR, #2 has north and southbound flights and also flights descending into JFK.  #3 is mostly JFK departing flights going south and #4 seems to be mostly departing flights out of KLGA (and EWR??).

This set up doesn't even consider western approaches and departures from the NY area.  132.875 handles mostly westbound flights and 128.575 handles mostly inbound flights from the west and hands off to 124.625. 

But this is all just hypothetical  grin

So out east, put a splitter in so you can feed your antenna to both radios, add another sound card & stream to your PC. Then, if they both tend to be busy at the same time, put 134.0 on one radio and 135.8 on the other. Then put 124.525 on whichever radio it doubles the least with and 132.3 on the other. If you can set delay by channel, put 2s delay on 134 and 135.8 and no delay on the others.

Same schema at home... group frequencies that either have a common progression (so you hear a flight transitioning between channels) OR that have operations at different times. For example, if you only had one feed you could group JFK CAMRN and ROBER together because they are not always active at the same time. First and foremost are any channels where you get both sides of the conversation... try to have a radio for each of them, turn on their delay so they hold the two-way and keep the other shit from breaking up the QSOs, and then pile in the rest of them according to conflict schedules (when two-way "A" is active, shit "B" usually is not).

If you don't get the ground side, I would probably just pile all the departure stuff, 3 & 4, on one radio, then split 1 & 2 among the other two or three radios. Ideally it would end up in three groups, something like NY area Departures, Arrivals & Overflights.

All I know is when I try to listen to feeds where the guy loads up the scanner, I never hear both sides of the conversation and half the airborne transmissions are partial due to scanning... it is largely incomprehensible and gets boring pretty quickly.

Soon (today) you can remove the North Mountain frequencies - a ZNY feed is going up shortly.

128.575 Sector 75 Milton High - enroute to New York, Allentown, Philadelphia, etc, and westbound flights
132.150 Sector 74 Broadway Low, enroute to New York
134.800: Sector 91 Williamsport Low, low altitude over central PA enroute to University Park airport (UNV) and Williamsport airport (IPT)

That should be a great feed, Dave. Does it get the ground side?

North Mountain is a great site. I had to go up there decades ago to fix a repeater nobody could get figured out. That feed, which I assume is on high ground, will probably be picking up 5-10% of all the flights in the country when you consider the bulk of the flights between the PHL/BOS corridor and the middle/upper mid-west pass overhead on their way to or from Slate Run.

Have access to a site where we can put a few receivers for more ZNY coverage - Camelback Mountain in PA.  Going to be putting some receivers there before the snow flies.

Should be able to cover Flint Hill (124.625/132.1/134.6), better coverage for Huguenot (132.6),    Colts Neck and Matawan may be too far.  Possibly Sparta (133.150).

I actually didn't have any of the north mountain frequencies in my feeds. This is nice! I guess Camelback is too far from 132.175 to get the ground side? That would be a nice bonus.

I think we can get all or most of the Elk Mountain RCAG freqs up there - I neglected to list those:

132.17500 ZNY34 Sector 34 Elmira High
128.50000 ZNY34 Sector 34 Elmira High (Spare)    
133.15000 ZNY36 Sector 36 Sparta Low
134.45000 ZNY51 Sector 51 Lake Henry Low

I did some recon up there in June but I can't find my notes.

The specialty up there will be extreme filtering (bandpass/notch).

Got that covered, too. Lot's in the junk pile and I'll be happy to brew up stubs, resonators and such. Let me know if you need some help. You know me... I'll do it for free if you just get an ARINC 129.4 receiver up there, since they have a ground station at IPT. If you can pick that up, or even hear it way down in the grass, I've got the proper antenna, hard line and GRR-23 ready to go... installation included. You know how bad I want a good domestic ARINC station for all those flooded toilets and gear indicator lights, and that location is dead center for the NE net, probably get both sides of every QSO. Then we can break 129.4 out of the JFK feed and just run oceanic out of there, or I'll put a voting system on 29.4 for the flights that are too far east for IPT to pick up.

I'll have a date set within the next few weeks - will keep you posted.  Williamsport will be too far from this site - behind Scranton/Wilkes-Barre hills, but we'll see.
