Westcom Encryption: Des Moines Metro Scanners Go Dark
Westcom — the consolidated Emergency Communications Center serving six Des Moines-area cities — has moved to encrypt all of its radio channels, taking police, fire, and EMS dispatch off public scanners (WHO/weareiowa). The move silences a whole metro dispatch center at once, not just a single agency — and Westcom's stated justification, AI scraping of scanner traffic, is reasoning other agencies nationwide are likely to copy.
A Whole Metro Dispatch Center Goes Dark
Westcom, formed in 2001, handles 911 dispatch for Clive, Norwalk, Urbandale, Waukee, West Des Moines, and Windsor Heights. The center announced it will encrypt all radio channels — police, fire, and medical traffic — removing them from public scanners. Local scanner groups report the channels have gone quiet as of late August 2026, though the exact switch date has not been officially confirmed.
Why Westcom Cited AI Scraping
Westcom called the decision "difficult" and said it was reached with all member agencies. The center explicitly cited "AI scraping" — AI-generated articles and minute-by-minute first-responder update sites that "lack context, consent, or accuracy" — along with an incident in which a mental-health subject's name, address, and phone number were posted online after appearing in dispatch traffic.
The Register Confirms the Decision
The Des Moines Register confirmed each city agency "made the difficult decision to implement encryption on all Westcom Emergency Communications radio channels."
Listeners Track the Move on ISICS
RadioReference listeners followed the transition on Iowa's statewide ISICS trunked system, where a claimed "Oct 26, 2026 CJIS deadline" was debunked by veteran members (RadioReference forum). That claim matters: there is no federal mandate forcing agencies to encrypt on that date. Encryption remains a local choice, and the real conversation is about what listeners can still hear after October 26, 2026 — and the CJIS 2027 timeline — not a single switch that flips everyone dark at once.
What Iowa Listeners Can Still Hear
Even with Westcom dark, Iowa's ISICS system carries many agencies that remain unencrypted, and fire and EMS in surrounding counties still broadcast in the clear. A Baofeng K5 Plus tri-band police scanner, pre-programmed to your zip code, is built for exactly this: tracking police, fire, and EMS across multiple bands on the channels that are still open.

FAQ
What is Westcom?
The consolidated Emergency Communications Center serving Clive, Norwalk, Urbandale, Waukee, West Des Moines, and Windsor Heights; it was formed in 2001.
When did Westcom go encrypted?
The decision was announced in March 2026. Scanner groups report the channels quiet as of late August 2026, though the exact switch date is not officially confirmed.
Why did Westcom cite AI scraping?
It said AI-generated articles and minute-by-minute first-responder update sites "lack context, consent, or accuracy," and pointed to an incident where a mental-health subject's personal information was posted online.
Does the October 26, 2026 deadline force encryption?
No. RadioReference veterans debunked that claim — there is no federal encryption mandate forcing this move; it was a local decision.
Which services are affected?
Police, fire, and EMS dispatch for all six member cities.
Can I still listen in the Des Moines area?
Westcom channels are dark, but other agencies on Iowa's ISICS system and fire/EMS in surrounding counties may remain unencrypted.
Bottom line: Westcom's encryption silences 911 dispatch for an entire six-city metro — police, fire, and EMS at once — and its AI-scraping justification is one other agencies will likely copy. The federal deadline excuse is a myth: encryption is a local choice, and while Westcom is dark, plenty of Iowa channels remain open for a pre-programmed scanner to find.
