.. (although it is kind of hard to know what RF channels match up to the station numbers)
This actually is pretty easy to find out, thanks to the FCC's
TV Query
Scroll down to 'stations within a radius' and enter a radius and your coordinates (or use the link for reference coordinates of communities). The actual channel is output in all of the lists, regardless of the 'channel branding' that the station may be using.
The same functions are available, incidentally, with the AM Query and FM Query pages; I have spent the last twenty-five years either full-time or contract as a broadcast engineer, and when I was full-time these pages and their precursors were my bread-and-butter.
(And, in case anyone was wondering, my avatar is related to one of the oldest transmitters I worked on... it's an RCA 892R power triode which weighs many pounds and stands about two feet tall.... typical application had two 10VAC filament transformers at 50A in quadrature (to eliminate hum) with a plate voltage around 10KV with up to 2A plate current, 4KW max plate dissipation and 12KW max signal plate input power; for an AM these things were used for 5KW transmitters as a single-end class C RF plate modulated output amplifier driven by two of them in class B push-pull as the modulator....... <insert Tim Taylor grunt here> Now that's vintage, since that transmitter was built in 1946.)
Also somewhat incidentally, and speaking of vintage, back in 2000, the FCC released a massive archive of code from an old VAX, and if anyone wanted to play with some vintage FCC FORTRAN code for a VAX (including some web CGI scripts
in FORTRAN!) I still have that archive (38MB uncompressed as I recall). EDIT: The FCC still has the page with the archive up and online; see
https://transition.fcc.gov/oet/info/software/vaxcode/ (7.7MB compressed ZIP, even though the page itself says 7.8kB, it's wrong) .
