Not a difficult task at all actually, just tedious given the number of repeaters in the state, then cross referencing them in TOPO or Google Earth and adding them to the .gpx file. The myth that repeater sites are a closely guarded secret, so much so that national security is dependant on them remaining secret, is nothing more than a ham radio 'ol wives tale. Finding the sites was the easy part.

I just plugged them into TOPO and looked for the USGS ratio tower symbol or double check them in Google Earth by entering the Lat/Long then zooming in and actually seeing the radio tower.
Other sites gave a detailed description of the site ie "The CRA 145.145 machine is located 20mi west of Denver on Squaw Mt at 11,xxx feet". It's easy enough to look at a topo and find Squaw Mt west of Denver. Find the 11,xxx foot contour and follow it till you find the radio tower icon.
A few machines proved more difficult but their descriptions contained clues. If the descriptions stated they were co-located with a public service or commercial site, I would look up the site owner in the FCC's ULS. Public safety and commercial sites are listed by Lat/Long in ULS. Example: if the description said "The 147.225 repeater is co-located with the Monroe County Sheriff's repeater on top of Methodist Hill" I'd look up Monroe County's License in the ULS and it gives the co-ords of all the sites operated under that license. I'd plug them into TOPO till I found the one on Methodist hill. (actually it's easier than it sounds).
I still found that the location of 2 machines, in the SW corner of the state, to be elusive. So I looked up the owner in QRZ and shot him an email. I explained I was a ham (included my call) and the purpose of my project. The owner sent me the co-ords of the last 2 machines that I needed to complete my project.
