NTIA Government Master File of Federal Frequency Assignments

Searched the file for freqs used by ARTCC Chicago Center using "ZAU" as the search parameter. Some freqs were found, though many weren't.
On a positive note, I was able to confirm "new" freqs used in ZAU low sector 35 (BEARZ), even a note saying that 134.875 replaced 127.800 (the VHF freq that was in the Radio Reference database for this sector). Use of 134.875 was confirmed via listening.
Info was submitted and the RRDB has been updated.

Alrighty folks. College spring semester is over and I finally have a social life and time to complete (many) pending projects. Currently, I've been running into a lot of duplicate sites, which combined with the sheer number of frequencies has made for a much slower process. I can post what I have done, but be warned that this is an incredibly slow process since I'm trying to verify the sites location as I go, to make sure you all have the best possible information from this document.
ArkTex, I hope all is well with the Emergency Management path you're seeking. Former POTUS Security, Continuity of Government (COG), Continuity of Operations Planning/Plan (COOP), Emergency Program Manager, military retiree Bubba here. Have a PROTIP recommendation proposal for you...
Once you have the database compiled. Look for the Department of Homeland Security (DHS) frequencies (Recommend Using Notepad++ and/or Excel). Then look at the concentrations in particular states. Create a map (Google Earth, ARCGIS, etc), and create transmission distance circles from the Site Coordinates. Where these intersect with multiple circles is a general location of "Sensitive Locations"...
Putting my FEMA NIMS/INCIDENT/NATIONAL SECURITY AREA (NSA) COMMANDER Hat On...
Recommend you become smart with CISA/NIFOG if you haven't already...
I've attached two other lists of locations the lazy folks at NTIA left at the very end of the 2008 REDBOOK, Annex O (Last Annex, Last Pages)....
Look Forward to Your Finished Product!

Well anyhow.
@ArkTex may I respectfully suggest asking the NTIA for a newer copy of the unclass GMF via a FOIA request? The data is now closing on a year and a half old, and that info is updated daily, just like the FCC database. I think the last time I did it ran about 3 weeks before I received it, and, much like the one posted to the web, was full of chaff (i.e. co-channel wireless mics for fast food restaurants, etc).

exactly why my progress stalled. I’m waiting on the. NTIA to process my FOIA request. If anyone else would like to take a crack at it be my guest.

You may have to fight with them if they want to classify your request as "commercial use" and charge you. I've had that argument every time lol.

I’m going to work on it more when I get back to my office. I have work on the DTRS later on next week.
Looks like a programing project is in my future. Thanks

Thought I would kick a dead thread and provide an update. The NTIA still hasn't responded to my FOIA request, so no good there. Still working on the most recent available until I get a response from the NTIA.
Fighting the good fight!

Haven't responded at all, or provided the 'we can't get it done in the time legally allotted so hang on'?

I got a letter from them saying they can’t get it done due to “updates”, no ETA given. Would y’all who are interested want me to just keep working with what I got, or do you want me to wait for the NTIA to respond?

Well, as long as the format doesn't change, you would be ahead of the game to import

It's probably updated every day just like the FCC databases. That could be an excuse to not give you anything at all.
Having spent a lot of time on both sides of things like this, I'd be curious what they meant. In the best light, they might be getting a new system that isn't happening on schedule (as usual), perhaps because the old one died, as it has the appearance of having been text-to-PDF'd from something pretty old. There's the chance, though, that people complained too much about that near-impossible-to-parse format and they decided not to send it out that way any more, but it may still be producible. Might be worth asking them for more details.

I’ll see what I can do. I’m only a quarter of the way done with the original due to how much effort it takes just to ensure I’m not duplicating or putting missed information in there. I apologize for the amount of time this has taken.

I would respond asking for clarification.
If updates mean technical issues, not much you can do.
Otherwise, they legally have to provide you with an estimate.
If it is as someone else suggests, that every day is an update, the cure for that would be to tell them you want the output from a particular day.
Having some experience with multitrack FOI requests spanning a decade (they drag their feets), I say go with what you have. It may be a long time before they come off of anything.
