GMRS Radio Guide for Cedar Rapids Drainage Crews

By Cedar Rapids Drain Pros · October 18, 2026

Drainage jobs mean trenches, pipe and a machine in somebody's yard. A mobile GMRS radio is one way to keep everybody talking. Below: GMRS basics, the Midland MXT295, real-world range, and what the FCC requires.

First, what is GMRS?

GMRS stands for General Mobile Radio Service. It is a licensed FCC radio service on channels around 462 and 467 MHz, used mostly for short-distance, two-way voice talk with handheld radios, mobile 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. None of the channels belong to anyone, so you listen before you 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.

• NOAA weather channels and weather alert tones
• Hookups for a PA speaker, wired intercom and outside speaker
• Bluetooth mic range of up to 100 feet from the base unit
• A hideaway base unit you can mount out of the way, powered by a DC vehicle adapter
• Automatic noise canceling for engine and wind noise
• The 22 standard GMRS channels and 8 repeater channels
• 154 privacy codes (50 CTCSS and 104 DCS)

Plan on mounting the external antenna it needs, high and centered on the vehicle if possible. Per the manual, the radio drops to 5 watts on channels 1 to 7 and will not transmit on 8 to 14, because FCC rules say so.

How far it really reaches

According to the FCC, GMRS range runs from one to twenty-five miles. Station type, terrain and repeaters make the difference. Direct, radio to radio, a few miles is a fair expectation. Terrain and buildings shrink it.

Repeaters stretch it. A repeater sits up high, listens on one channel and retransmits on another, and the MXT295 has 8 repeater channels to use one. Linking repeaters over the internet is against FCC rules.

Where it helps a drainage crew

• Warn the crew before a load of gravel comes in.
• Call for more pipe, fabric or gravel from the truck.
• Hear a weather alert before heavy rain.
• Check grade from the far end of the trench.

Around Cedar Rapids, weather changes the plan fast. The NOAA weather alerts help the crew hear about it in time.

The license: required, cheap and simple

The Amazon listing skips this part. Midland and the FCC do not. 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.

• Cost: $35 (see the FCC fee schedule).
• One license is good for 10 years.
• You do not take a test.
• Only adults, 18 and up, can apply.
• Your immediate family can use it too. The rule lists spouse, children, grandchildren, stepchildren, parents, grandparents, stepparents, brothers, sisters, aunts, uncles, nieces, nephews and in-laws.
• Crew members who are not family each need their own license. New GMRS licenses go only to individuals, not businesses.
• The FCC assigns you a call sign to use for station identification.

Bottom line for a drainage crew: one license per person outside the owner's immediate family. No test, $35, 10 years. 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.

Before you buy

• Pick an antenna spot high on the truck, away from fiberglass.
• Set a crew channel and privacy code ahead of time.
• License first, then key up.
• The radio is built for a 12-volt negative-ground vehicle.
• Pair the Bluetooth mic and test it at the job before you need it.
