It sounds like they have 33.98 which is the old county wide dispatch freq along with Millcreek Fire Control's UHF frequencies and the City of Erie's VHF freqs.
I was pretty excited when I saw it. I grew up in Erie and my first exposure to scanners was my neighbor's (a Volunteer FF) Plectron monitor. That was the late 60's/early 70's and West Ridge VFD still used a fire siren. I remember saving my money to buy my first scanner, a 10 ch. Regency monitoradio. I had to buy crystals one at a time but I'm sure the first one I bought was 33.98.
Millcreek is no longer on 33.98 having moved to UHF a few years ago. It sounds like they are using the same Plectron tones they've been using for at least the last 35 years.
