Construction Site Frequencies

[nyFreq]

Hi all - forgive me if this isn't a good place to post this, but it seemed as good a place as any. Does anyone have any tips of how I can discover the frequencies used by workers on a local construction site? I work near 432 Park in NYC - a major construction site. I thought it would be fun if I could listen to the various coordination going on at the site - crane operator, other workers, etc. Not sure what kind of system these sites normally use. I tried searching around and couldn't really find any info. Are there certain bands I can scan in that are more likely than others to be what's used?

Thanks!

These would be a good place to start.

If you know what companies are doing the work you can search for licenses in the FCC database.

If you have a modern Uniden Scanner just do a Close Call Scan.
