According to Phillyscanner.com LMFD has 16 simplex channels in the 458 MHz range plus the 453.65 operations repeater. Channel 1 is a company-specific frequency and the rest are apparently available through all radios. Ch8 is a fireground frequency, which makes sense for a specific local incident, and it is reportedly 458.5375. Phillyscanner's Montgomery County page lists all of the channel assignments. Phillyscanner is a paid site so I don't want to undermine Joe C. by posting the whole list here though.

Reason: Wrong frequency range for simplex channels
