Nice job, its good to see another local facility come up. Have you tried these two ZNY freqs? You're not that far from the transmitters so it might be worth a shot..

Thanks. I'll give those a go. I've got a preamp on order, so that might help things if I can't get a clear enough signal yet...

Just gave it a try. I can hear both the planes and ATC on both freqs, with some noise on the 132.2 ATC transmissions. The quality on 132.2 is about what I get on 124.65, while 133.47 is about what I get on 124.10. Looks like I'm going to be buying some more scanners...

That's awesome, 133.47/ "Harrisburg 10 High" can get to be very busy for southwest bound New York departures. Are you ok with putting those two freqs on one feed and combine the two MDT App freqs on another. Just until you get another scanner.

I'd rather keep the KMDT freqs on their own scanners for now, as one of the reasons I wanted to put this up was for IFR students out of my home airport to be able to listen to recordings of their transmissions to improve their radio technique, and that works best with discrete feeds. But I will make sure 133.47 is the next feed I put in. I had planned on addding the local tower freqs first, but Harrisburg High will be top priority. Shouldn't be too long. I've got a PC (a $139 off-lease machine, which is perfect for this!) coming Tuesday to act as a dedicated box for the feeds, and I've also ordered a Delta 44, so I'll be able to add another scanner PDQ. My biggest question now is what kind of splitter / preamp to use. I've got a simple preamp on order, and I was figuring on passive splitters after that, but I might bite the bullet and switch to an active splitter like an ASA15.

I'll keep everyone updated.

BTW, do you work at PHL Approach?

Well, forget the ASA15. It's only spec-ed up to 70MHz. Sad

Great to have another feed up ! And it's really nice having another "discrete" feed that concentrates on one area rather than trying to please everyone at the same time by loading up one radio with too many different sectors/frequencies. I wish more people could see the advantages of doing it this way. DJ

I think everyone can see the advantages.  smiley  The issue is that not everyone can afford the setup and/or manage the complexity.  That is one of the issues we've been trying to solve in the busier and more interesting airspace with the "superfeed" machines.

We can fund or help fund setups like this for feeders who may not have the financial means but who live in very good locations near busy airspace.  As long as they commit to do their part in helping to keep the feed(s) running.

Just managed to pick-up a couple of PRO-2055 scanners (new in box) for $67 each on eBay. Bad displays, but I don't need the display for this application. They list at $199, so that's a pretty good deal.  smiley Should be able to add another couple of feeds in the next week or so...

You're missing my point, of course more radios are better, but what I'm getting at is if only ONE radio is available it's better to concentrate on one area or sector rather than trying to scan everything at once. This is especially evident at moderately busy airports that have clearance/ground/tower/approach on all ONE radio. The BWI/CLE/CMH/DAY/MHT/PBI/SAT/SDF feeds are some examples with too many frequencies on them. I realize it's a matter of personal taste and some people think that it's better to scan everything. I just don't think it is and all I'm saying is it's nice to see new feeds, like MDT here, that don't do this. DJ

Just an update on this... I've finished moving the two KMDT Approach feeds over to a Linux box with a Delta-44 audio card, and I've got some more scanners and a splitter coming tommorrow, so I'll be able to add another couple of feeds. I'm going to start with KMDT Tower and a combined ZNY feed from 132.20 and 133.47, and then when the second Delta-44 turns up next week, I'll split ZNY and add KLNS Tower and KCXY Tower. 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.
