The Midland Base Camp XT511 is a FRS/GMRS two way radio with emergency attached Dynamo crank power. The Base Camp XT511 can also operate on battery power (included rechargeable battery or 4 "AA"). The rechargeable battery can be charged using the AC/DC adapters, or by turning the Dynamo crank.
The XT511 also features a flashlight, digital clock with alarm, an AM/FM radio, two-way transceiver and a NOAA weather alert radio. It supports 22 FRS and GMRS channels with 121 sub-audible tone squelch (CTCSS and DCS) codes per channel. Hands-free (VOX) mode is supported and a corded speaker microphone is included. A USB connector is also provided that allows you to charge your USB enabled devices such as a mobile phone.

Specification
- 22 Channels with easy button access
- 121 CTCSS codes to help you block other conversations
- NOAA Weather Alert Radio with auto alert when monitoring weather channels
- 5 Call Alerts - Different call tones to notify you of incoming calls from your group
- eVOX - 3 Sensitivity Levels - Easy voice activation
- Keypad Lock - Locks in your selected settings
- Flashlight
- USB Connector - Allows you to recharge your cell phone in an emergency
- 5 Power Options - Uses 4 standard "AA" batteries, Rechargeable Battery Pack, Dynamo Crank, AC Adapter, or DC Adapter
- Dimensions - 7.25 x 6.38 x 2.75
power options
The XT511 can be powered with AA batteries, its internal rechargeable battery, a DC power supply, AC power supply, and the crank arm. The included 700 mAh, 6.0V, rechargeable Ni-MH battery pack can be charged by the power supply or by use of the crank. To get the best charging condition, it is recommended to charge the battery pack thru the Dynamo Crank with the radio turned OFF. Only use our NiMH battery pack.
external mic/speaker
The microphone speaker attachment uses the standard ham radio style twin TRS connector jack harness. One part of the plug fits in the microphone jack,and one fits into the speaker jack. While connected the built-in microphone and speaker on the front of the radio are disabled. The handheld speaker/mic also has an input TRS jack on it for attaching an earphone.
transmitter
High and low power settings let you adjust the radio's transmit power to conserve battery life. Max transmit power: XT511 GMRS Power: 1.0815 FRS Power: 0.2622 final amp stage 9.9 output to antenna 4W max
Maximum range can only be achieved over water or open rural areas under optimum conditions.
receiver
- GMRS: 462.550 - 467.7125MHz
- WX: 162.400 - 162.550MHz
- AM: 530 - 1700kHz
- FM: 87.9 - 108.1MHz
Review
Midland's XT511Base Camp emergency crank radio serves as an all-purpose communication tool with two-way radio, NOAA weather and AM/FM radio functions. The radio is useful to take along on a camping trip or hiking. It is also useful for neighborhood communication. Examples of use include monitoring the kids, as a shop to house intercom, or coordinating a community event. It is both well suited for recreational use as well as being an emergency tool.
Having the ability to turn a crank for power is something that makes this a true emergency radio. I tested this having the unit gone completely dead with the rechargeable batteries installed. I was able to crank up enough power in a couple minutes to make a transmission on high to announce my position. Transmitting consumes more power than monitoring or listening to broadcast radio, so this is better than expected for manually generated crank power.
There are two transmit power settings for the GMRS channels. FRS only channels are set to low power and cannot be changed as to comply with FCC Part 95 regulation. Setting transmit power to low helps to conserve battery life while operating on DC power. The range is comparable to the standard bubble pack two-way walkie-talkie. It does not have extraordinary range, however, it is comparable for a unit with attached antenna. I was able to easy communicate in town between this unit and a mobile, neither operating on more than 1 watt, over 12 city blocks with hills and trees being common where I live.
There is no manual squelch for the transceiver. Sometimes weak signals from your party can be missed because the hard coded squelch cuts the transmission out. It does have, however, a "monitor" button that will deactivate squelch. While in this mode you will hear static and weak transmissions. So basically, this unit can operate squelch on, or off.
Another feature lacking in this model is the ability to have a received transmission on your set channel "cut in" over the broadcast radio, such as some of 2-meter walkie-talkies do. I want to listen to music but not miss a transmission from a family member using a handheld trying to reach me at "base camp." I have a cheap wrist style walkie talkie that will do this, so I don't see why Midland couldn't have implemented this as a feature in their XT511.
The optional attachable microphone also serves as a mini handheld speaker. This gives the feel of a classic CB Radio with one strange exception. As the user manual states, "When the HAND MIC is connected, all audio will play through the HAND MIC because it is a speaker mic. This is normal operation." I didn't like the fact that when attached, all speaker audio ceased coming from the base unit and only emitted from the handheld speaker/microphone. I would prefer it was more like a traditional transceiver whereas the handheld button mic was a mic only and sound continued to emanate from the base unit. By cutting the speaker plug from the connector the hand attachment becomes a mic only. However, this is a modification that would void your warranty.
Midland, please add two valuable features missing from this model:
- Ability to listen to broadcast radio while monitoring one of the 22 FRS/GMRS channels. It should cut in when a transmission is received.
- Ability to adjust the squelch level on the transceiver.
- Ability to switch sound from mic back to base unit while mic is attached
Overall I liked the size of the unit and the attached carry handle is a benefit. The unit rests well in an upright position so that it doesn't fall over easily on an non-level surface such as an outdoor picnick table. And finally, the unit retained a charge throughout the day on battery power while monitoring and scanning FRS/GMRS channels with some light transmitter use. Until something better comes along in this very budget friendly price range with those missing features mentioned prior, I will recommend this unit.
Special Feature Guide
The basic features are easy enough to figure out. Here some of the enhanced features are discussed.
DUAL WATCH
Your XT511 Series has a DUAL WATCH function, to enable user to monitor 2 selected channel/privacy code for any activity. It is similar with the SCAN function but will only monitor 2 channels instead of the whole 22 channels. The first channel/privacy code is the current setting, the second channel/privacy code is the one you will set on the MENU. To turn on the DUAL WATCH function, press the MENU button until the DUAL WATCH icon appear while in the right an “oF” icon appears. Select the second channel by turning the TUNING knob.
NOAA WEATHER ALERT
If the radio receives a WX ALERT signal from a designated NOAA station while on AM/FM or GMRS/FRS mode, the radio will beep for 20 seconds while the NOAA WEATHER (WX) ALERT icon will appear blinking on the display while the FLASHLIGHT and the display illumination will blink altogether. In this case, the user should set the BAND switch to WX position to listen for any weather alert broadcast.
Antenna Mod
The really limiting factor on the Midland XT511 is the antenna. It appears to be only an 1/8-wave antenna. If it were possible to replace the antenna there would be a dramatic improvement in both transceiver reception and range. It should be possible to dismantle this radio and hack a BNC connector as a replacement for the built-in antenna.
