Iowa City Drainage Crews: Is a GMRS Radio Worth It?

By Iowa City Drainage Pros · October 18, 2026

French drain crews dig, lay pipe and backfill, often with a mini excavator running. A two-way radio in the truck fixes a lot of that. We cover GMRS basics, this radio, honest range, and the license.

GMRS in plain English

The General Mobile Radio Service, or GMRS, is an FCC-licensed service near 462 and 467 MHz. Most people use it for short-range push-to-talk between handhelds, vehicle radios and repeaters.

There are 30 GMRS channels. 22 are shared with FRS, the license-free radios sold in blister packs, and 8 are repeater channels. Mobile and base radios can run up to 50 watts on the main channels. Channels are shared, so the rule is listen first, then talk.

What the Midland MXT295 does

This is a mobile radio, meaning it mounts in a vehicle. The big deal for a drainage crew is the wireless Bluetooth mic: you can leave the cab and stay on the air.

• 154 privacy codes to cut down on chatter from other groups
• 15 watts on high and 5 watts on low
• An IP67 waterproof and dustproof build
• Talks with FRS handhelds and other GMRS radios on shared channels
• The 22 standard GMRS channels and 8 repeater channels
• NOAA weather radio with weather alerts
• A hideaway base unit you can mount out of the way, powered by a DC vehicle adapter

It needs an external antenna, mounted as high on the vehicle as you can. Midland's manual also notes FCC limits: 5 watts on channels 1 to 7, and no transmitting from a mobile on channels 8 to 14.

How far it really reaches

The FCC says a GMRS user can expect one to twenty-five miles, depending on the type of station, the terrain and whether a repeater is used. Radio to radio, with no repeater, plan on a few miles. Hills, trees and buildings cut that down.

A repeater on a hill or tower picks up your signal and sends it back out, which is how you reach the far end of that range. The MXT295 has the 8 repeater channels for this. The FCC does not allow linking repeaters over the internet to stretch coverage.

Where it helps a drainage crew

• Call for more pipe, fabric or gravel from the truck.
• Coordinate with a second crew on another Iowa City job.
• Check grade from the far end of the trench.
• Hear a weather alert before heavy rain.

For crews working outdoors around Iowa City, the weather alerts and the sealed build are a big part of the appeal.

The license: required, cheap and simple

The Amazon listing does not mention a license, but the radio does need one. Midland's MXT295 manual says: The MXT295 operates on GMRS (General Mobile Radio Service) frequencies, which require a Federal Communications Commission (FCC) license. You must be licensed prior to operating your MXT295 radio. The FCC rule, 47 CFR 95.1705, says: A valid individual license is required to operate a GMRS station.

• The FCC fee is $35.
• It lasts 10 years, and you can renew it.
• You do not take a test.
• You must be 18 or older.
• Family members are covered. Per the rule, that means spouse, children, grandchildren, stepchildren, parents, grandparents, stepparents, brothers, sisters, aunts, uncles, nieces, nephews and in-laws.
• Employees outside the family need their own license. The FCC issues new GMRS licenses to individuals only, not to companies.
• You will be issued a call sign, and you say it on the air to identify.

So for most drainage outfits, each non-family crew member gets their own license. It is $35 and good for 10 years, with no exam. Apply through the FCC; start at the FCC GMRS page.

One exception in the rule: a licensee may let anyone use the radio if it is needed to send an emergency message.

A few things to check first

• Walk the mic out and test it before the first real job.
• Figure out the antenna mount: high and centered works best.
• Agree on a channel and privacy code with your crew.
• Check that the truck is a 12-volt negative-ground system.
• Confirm that hired help has their own license.
