501-999 Watts
The Yaesu VX-7R is a triple band 50MHz (6 meters), 144MHz (2 meters) & 440MHz (70 centimeters) handheld amateur radio transceiver with extensive receive coverage, and leading-edge features. The American version also transmits on the 222 MHz (1. more...

25 meters) band, making it a quad band transceiver. The radio's magnesium alloy case is available in black anodized or silver (clear anodized). The model number suffix "B" or "S" denotes which color, black or silver respectively.
The radio is designed to operate in extreme conditions, and is sealed against water and chemicals, making it well-suited for emergency-services duty. Available accessories include remote microphones, earphones, and adapters for digital communications modes.
The VX-7R can be programmed directly from the integral keyboard, or using a computer, linked by a cable which connects to the speaker/microphone connector. There are several free and inexpensive programs available with which to modify settings.
The DTMF memories allow strings of DTMF tones to be stored, allowing it to be conveniently used in a "remote-base" system with a radio such as the TS-2000.

Frequency Range Transmit:
50 - 54 MHz – 5 Watts;
144 - 148 MHz – 5 Watts;
222 - 225 MHz – 300 mW (US version);
430 - 450 MHz – 5 Watts;
Each band (except 222MHz) can be switched between 5 watts, 1 watt, 300 milliwatts, and 50 milliwatts. Through an undocumented test menu, it is relatively easy to change power output within ~10 milliwatts to 5 Watts for each power level. This is useful because the small battery will last significantly longer at 2.5 Watts than 5 Watts (about 1/2 current drain for a very small reduction in range).
Characteristics
The VX-7R can transmit a 1 watt AM carrier on the six meter band. While the usefulness of this feature is disputed, it is fun to try. It is recommended to use an external antenna tuned to the lower part of the six meter band for this feature.;
The VX-7R is often used for FM voice communications through low earth orbit amateur radio satellites.;
The VX-7R cannot transmit and simultaneously receive on another band as some other "dual-receive" HTs can, but the dual-receive on any combination of bands functions reasonably well. The "Sub" VFO is limited to frequencies around the 50, 144, and 440 amateur bands, while the "Main" VFO has a much broader frequency coverage.;
