Montgomery County (PA) Quick Call II tone sets

This list is not definitive. Its guess work. It has been cobbled together from over-the-air recordings of MontCo DPS audio dispatch, and tone frequency analysis. Entire stations may be missing, assignments can be incorrect, and agencies that utilize multiple sets of tone pairs for dispatching apparatus only make it harder to discern who gets activated by what. If an agency was in a stacked page, or has not been dispatched in the time-frame the logging software was running, it was not recorded.

The MediaWiki helper (linky, linky ->)here, did most of the heavy lifting, and generated the table you see as follows. It is cruel and unusual punishment to drop a messily coded HTML table in for anyone else to try to easily edit.
