That'll leave me one spare channels -- better start looking for other freqs! Are suggestions as to what I might be able to pickup from here? I might try the Potomac freqs south of here.

Are you saying there is going to be 4 separate radios ? If so this is what I would do as an initial test.

Radio 1 - MDT approach

124.100
118.250
126.450

Radio 2 - ZNY 1

132.200
133.475

Radio 3 - Towers

124.800
119.500
120.900

Radio 4 - ZNY 2 (option 1)

128.000
132.500
134.325

Radio 4 - ZNY 2 (option 2)

134.800
123.625
124.900
132.875
128.575

A few questions. Does MDT approach use 118.250 very often ? Can you hear LNS Tower from your location ? Can you hear MUI Tower 126.200 from your location ? (maybe include that on the Tower feed).

If you didn't have it already this is the latest ZNY frequency info.

http://web.nbaa.org/public/ops/airspace/ZNY_LTA0601.pdf

I believe the ZNY Joliet site is 28nm northeast of MDT, can you hear the ZNY controllers at all on 132.500 or 128.000 ? (note: the LRP sector frequency is listed at 133.675 but they have been using 128.000 instead, I'm not sure if the transmitter site for 128.000 is at the same Joliet location ? Anyone know ?).

From my experience flying in the area, they rarely use 118.25 unless they've got a problem with another transmitter. And, yes, I can get KLNS tower on 120.9 fine from here. Re the setup, it's going to six radio to start with, and hopefully eight in the end. I'll check out those ZNY freqs and see what I can find. My location is N40.00723, W76.55731 if it helps.

FYI, I think the new 128.0 freq has been possibly swapped with the old backup 33.17. They can't make up their mind. Yes that transmitter is in Joliet still. I was looking for Joliet on GE while looking for the location of Big Flat and I just couldn't find Joliet. I could have sworn it was somewhere out there.

Just tried putting the Joliet freqs in the scanner, and I can pick-up ATC and airplanes. I'm going to work through the ZNY freqs and see what else I can get... Which ZNY sectors already have feeds?

I see what you mean, a couple of days ago when I checked that sector they were using 128.000, but just checking now (at 2000 EST) they are using 133.175.

You can find Joliet PA using MapQuest, it's position is around N40 36 43 W76 27 14, that would put it around 36 nautical miles north of the feeders location.

Modena, about 40 nautical miles east of your location, also has a ZNY frequency on 135.450, and ZDC has a transmitter at Modena as well on 132.525. Can you hear the controllers on those two frequencies ? There is also a HIWAS off the Modena VOR on 113.200, can you get that ?

Can't get Modena, Millville or anything else beyond Big Flat and Joliet.

Still, that's not too bad! Might try some Potomac freqs next. Anyone got a map?

I don't have a sector map. If you didn't already know about it, you can pull up the Baltimore-Washington VFR Terminal Area Chart off the Skyvector site.

http://skyvector.com/

Here is a basic overview of the Potomac frequencies I'm familiar with.

118.675 = high (west)
118.950 = DCA initial departures (south, west, northwest)
119.000 = low (northeast) (status ?)
119.300 = ADW arrivals (final)
119.700 = BWI arrivals (final)
119.850 = DCA arrivals (final)
120.450 = IAD arrivals (west)
121.050 = high (southwest) (*)
123.825 = high (northwest)
124.000 = ADW area (status ?)
124.200 = DCA arrivals (north)
124.550 = BWI initial departures (northeast, south)
124.650 = IAD arrivals (south)
124.700 = DCA arrivals (final) (*)
125.050 = IAD initial departures (northwest, northeast, south)
125.525 = BWI arrivals (northwest, north)
125.650 = DCA initial departures (northeast)
125.800 = IAD arrivals (final) (*)
126.100 = IAD arrivals (north)
126.550 = high (east) (status ?)
126.650 = IAD initial departures (west, southwest)
126.750 = low (northwest-north)
128.350 = BWI arrivals (southwest, south)
128.700 = BWI initial departures (northwest, west)
134.200 = IAD arrivals (final) (*)

(*) = used when required

Any updates or corrections appreciated. DJ

I believe there are a couple Potomac frequencies covered by the BWI feed.  I know that 125.52 is one.  I would like to hear Harrisburg Ground on 121.7.

I doubt I'm close enough to MDT to get Harrisburg Ground.

BWI/DCA/ADW arrivals over BILIT.

GRACO - 124.55 / 317.425 - GRACO works all BWI departures and PCT overflights over PALEO, SWANN,
DAILY, SBY and PXT.

BWIFS - 119.7 / 290.475 - BWIFS is primarily responsible for arrivals to BWI RWY10, 33L, RWY4

BELAY - 125.525 / 291.625 - BELAY is responsible for CHP (Chesepeake/BWI), MTV (Mount Vernon/DCA) Area arrivals and over flights 9,000 feet and above. - Feeder to BWI from North.

Just wandering how it is going trying to add some frequencies to the KMDT feeds?

I've got three scanners to hook-up as soon as I get the mount points for them from Dave. The kmdt_twr mount exists but is currently running a test, but I'll move that over to tower tomorrow all being well.

Ok, we should now have kmdt_twr, zny_har and zny_mdt operating. I had a bit of an issue with the second sound card, and it's still running at too high a sample rate and eating processing power, but it's working. I'll let Dave know and get them announced.

Great, I am listening to ZNY 132.2 right now.  The only thing I have noticed is that after each transmission there is a couple seconds of static.  Not sure what could be causing that, but otherwise a great feed.
