Where would one search in the FCC database for ATC Xmiter locations?

Version 5 now complete. In this version I added a clear button for the map coordinates search facility and you can now search in kHz and MHz. Also, I noticed that the text version of the PDF I included was probably missing data as it was only some 27 MB in size. I used another convertor and I have a text file of some 70 MB in size. So huge difference. Keep in mind the PDF may have duplicates and likewise so may the text file. YMMV.

I'm getting an error that the file is no longer there?

Cool, glad it works for you. I spent a lot of time on that using my uber super duper coding skills... LOL I actually spent days with AI coding it... I don't know code for Adam, but know about JS functions and stuff to do things. :D I have some code here that's around 900 lines now and growing that will flash a Philips Hue light bulb red if a military aircraft is in my radius of 10 NM. It'll even send my a Pushover alert to my cellphone! LOL! I love AI. Some models are better than others.

I wish I knew what part of that was real and what part was just a joke. Or a prediction.

In my script you would enter
as a search term and then place a marker on the area you're interested in, set a radius in miles and you will find them...


Also, if you search for
EMERGENCY
you'll see in the whole of the document the use of frequency 168.6250 which is stated as:

USED FOR EMERGENCY GROUND-TO-AIRCRAFT AND EMERGENCY AIRCRAFT-TO-AIRCRAFT *RAD,0161
COMMUNICATIONS OR INITIAL CALL, RECALL, AND REDIRECTION OF AIRCRAFT WHEN
NO ALTERNATE FREQ IS AVAILABLE. NOT FOR GROUND-TO-GROUND COMMUNICATIONS.

Reminder – there's a lot of known channels in use that don't appear in the unclassified data (which was from a 2021 doc). I'm going to guess that the records are classified by default until someone successfully unclassifies them, same as in some other government data. Most of the dates are pretty old, too, so either that auto-classify policy came into effect some time ago or maybe NTIA is no longer the sole co-ordinator. It's certainly an interesting source of stuff that might be out there – it just shouldn't be taken to be authoritative or exclusionary. The channel pairing for VHF could be especially useful in figuring out where you might find the output of a repeater when you hear transmissions on the input.

I would myself replace "a lot" in your post by "most" from my experience.

I remember wondering about the aviation coverage, too. Don't exclude the possibility that they simply made a mistake in the query when producing the file. After all, we've been asked to believe that federal employees are all stupid and lazy. :(

That is an unfair swipe at federal employees. In my time with the U.S. Forest Service I worked among a lot of very dedicated employees, most worked unpaid overtime and obtained the Bachelor's degree necessary to work in their field. Most had decided by high school graduation or within a couple years after what their majors would be and what agency they saw themselves working for after graduation from college. While we got some good feedback to proposed projects or management methods, you would not believe some of what we received.
