Why the Right Two-Way Radio Frequencies List Matters More Than the Radio Itself
Seasoned installers will tell you—spending top-dollar on a flagship transceiver is pointless if you pick a channel already crowded by local taxis. A well-curated two-way radio frequencies list is the silent backbone of every reliable push-to-talk network, whether you’re running a downtown construction site or a ski resort spread across three peaks. But with regulators shuffling bands every few years and cheap import radios flooding the market, how do you know which frequencies are still “open” for business use in 2024? Let’s dig in.
How to Read a Two-Way Radio Frequencies List Without Going Cross-Eyed
First, understand the three tiers you’ll see on any professional chart: licensed business bands, license-free (but regulated) spectrum, and the wild-west 27 MHz CB/462 MHz FRS bubble pack toys. Each tier carries different power limits, emission types, and—critically—interference expectations. A tidy frequencies list will separate these tiers into color-coded blocks so you can spot the sweet spot for your application at a glance.
The Golden 450–470 MHz Business Pool
Ninety percent of UHF commercial traffic in North America lives here. The FCC’s Part 90 rules allow 12.5 kHz narrowband channels spaced every 7.5 kHz, giving you roughly 200 discreet “slots” if you narrow it down to county level. A typical two-way radio frequencies list will show these slots in 5-digit decimal (e.g., 463.1625). Bookmark the ones labeled “ itinerant” or “blue dot”; they’re license-free for two Watts or less on-site.
VHF’s Surprising Comeback for Open Land
Don’t write off 150–174 MHz. Yes, it’s noisier in cities, but for farms, golf courses, and coastal freight yards, VHF’s longer wavelength slips over hills that choke UHF. Modern DSP radios knock down engine static, making the classic MURS channels (151.82, 151.88, 151.94, 154.57, 154.60) a free, legal, and refreshently quiet option when you stay under two Watts.
Can You Legally Use “Offshore” Frequencies in the US?
Importers love to flash a glossy “99-channel” label, but flip the radio over and you’ll find a Chinese “409 MHz” band plan that sits smack in the middle of American amateur 70 cm. Transmitting there without an amateur ticket is a $20,000 party. Always cross-check any imported two-way radio frequencies list against the FCC’s Universal Licensing System (ULS) before you press the PTT. Trust me, the local ham club will hunt you down faster than the FCC—ain’t nobody got time for that drama.

Copy-paste these into your programming software, but confirm licensing for your county first:
- 467.7625 – FRS 14 (license-free, 0.5 W)
- 463.1625 – Blue Dot itinerant (license-free, 2 W, narrowband)
- 151.820 – MURS Ch. 1 (license-free, 2 W)
- 154.570 – MURS Ch. 3 (license-free, 2 W)
- 469.5125 – GMRS 17 (license required, 5–50 W)
- 464.550 – Common business, narrowband (license required)
Three Overlooked Tricks to Keep Your List Up-to-Date
- Sign up for FCC “Part 90 Newsletter” email alerts; they push major re-allocations 90 days before enforcement.
- Build a simple RSS feed from the NTIA frequency bulletin; federal agencies sometimes vacate spectrum that commercial users can lease six months later.
- Join your local Radio Club’s Facebook group—those old-timers live for gossip about new repeaters or busted spammers, and you’ll get real-time heads-up long before it hits the FCC bulletin. Yeah, it’s social media, but sometimes the grapevine wins.
Transitioning from Analog to Digital Without Buying the Wrong Frequencies
DMR, dPMR, and NXDN all promise “two slots per channel,” but remember: each digital mode still needs a physical frequency. Your frequencies list must therefore show channel spacing, not just the centre frequency. For example, a 12.5 kHz analog channel can host one DMR conversation, while a 6.25 kHz dPMR fits two. Mixing them on the same repeater without proper spacing is like trying to shove two double-parked trucks down a single lane—gridlock guaranteed.
Bottom Line: Build Your Own Master Spreadsheet
Start with the FCC’s master database, filter by emission designator, county, and power, then layer on your private notes (“Hotel across street uses Ch. 5—avoid”). Update quarterly, store in the cloud, and share read-only copies with every site supervisor. That living document becomes more valuable than any static two-way radio frequencies list you can download, because it’s tailored to your noise floor, your coverage map, and your licensing budget.
