Cell signals can be weak underground. A Davenport basement can be a dead zone. This guide covers one radio that fits that kind of work. We cover GMRS basics, this radio, honest range, and the license.

First, what is GMRS?

GMRS is the General Mobile Radio Service. The FCC licenses it for short-distance, two-way voice using handhelds, mobile radios in vehicles, and repeaters, on channels around 462 and 467 MHz.

GMRS has 30 channels: 22 shared with license-free FRS radios plus 8 repeater channels. FRS radios are limited to 2 watts; mobile and base GMRS stations can run up to 50 watts on the main channels. No one owns a channel. Listen before you key up.

What the Midland MXT295 does

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

15 watts on high and 5 watts on low
PA speaker jack, wired intercom jack and external speaker jack

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

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. Direct, radio to radio, a few miles is a fair expectation. Terrain and buildings shrink it.

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 waterproofing crew

Keep the basement crew in touch with the crew outside.
Call for a sump pump, pipe or sealant from the truck.
Warn the crew when a delivery is coming in.
Check in with a crew on another Davenport job.

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

The license: required, cheap and simple

You will not see a license mentioned on the Amazon page. It is still required. 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.
You must be 18 or older.
It covers your immediate family: 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.
The FCC assigns you a call sign to use for station identification.

So for most basement waterproofing 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.

Before you buy

Get your GMRS license first, or right away.
Figure out the antenna mount: high and centered works best.
Set a crew channel and privacy code ahead of time.
It is designed for 12-volt negative-ground vehicles.
Pair the Bluetooth mic and test it at the job before you need it.
