Verification Status
We don't yet have per-talkgroup data for McHenry Fire/EMS from the RadioReference API. The encryption scope and type above come from the RadioReference Wiki, which is community-maintained rather than independently confirmed channel-by-channel. Our automated matching put this at moderate confidence (70%) based on how closely the wiki listing matches this agency's name and county.
If you monitor McHenry Fire/EMS directly or have more current information, the fastest way to fix this is to update the RadioReference Wiki entry — our data pulls from there and from the RadioReference API on a regular refresh cycle.

That listing hasn't been verified against live talkgroup data, so confirm it at RadioReference before relying on it.
Can I listen to McHenry Fire/EMS on a police scanner?
Likely not, if the listing is accurate: our database lists McHenry Fire/EMS as fully encrypted using P25 AES-256, which no consumer scanner can decode. The listing is unverified — check the live RadioReference database for current status.
Why do agencies like McHenry Fire/EMS encrypt their radio?
The standard justification nationwide is officer safety and operational security, regardless of whether a documented local incident ever required it. The tradeoff that follows is consistent too: public oversight drops, and reporters lose the ability to track fire department response as it happens.
Can McHenry County reverse the encryption decision?
It can. The radios support open and encrypted operation equally well, so this is a configuration and a policy, not a constraint — and policies set by McHenry County officials are policies those officials can revisit when constituents press for it.
What can I do about McHenry Fire/EMS encryption?
Three things carry weight, in this order: a public-records request for McHenry Fire/EMS's encryption policy and radio recordings, a turn at the microphone during McHenry County budget discussions, and finding the other people locally already asking the same question. Individually these are easy to deflect; together they are not.
