There is a line of ultra-compact lower-power dual-band (2 m and 70 cm) transceivers that started with the VX-1R and was later updated with the VX-2R and VX-3R.
The lower (100 mW) power setting is adequate for repeaters out to 20 miles or so, and allows longer talk time.
[3] The VX-3R is the successor to Yaesu's previous models in the ultra-compact dual-band handheld FM transceiver segment, the VX-1R and the VX-2R.
The radio is designed to operate in extreme conditions, and is sealed at all openings to permit underwater submersion up to 1 meter (3 feet) for 30 minutes.
A demo model at Dayton Hamvention was held underwater for 8 hours at 1 meter depth, under power, without adverse effects.
A bug has been found, as the CTCSS decode may not work properly when the VX-6R is operating with external power.
It is designed to be shockproof, and is sealed against water and chemicals, making it well-suited for emergency-services duty.
Available accessories include remote microphones, earphones, barometric pressure sensor module, and adapters for digital communications modes.
Reducing output power allows the transceiver to be used over shorter communication distances for longer battery life.
The Yaesu VX-8R/VX-8E is a discontinued handheld transceiver (or "HT") for use on popular VHF and UHF amateur radio bands.
[9] Available accessories include hand microphones, earphones, a GPS receiver, a bluetooth unit, a barometric pressure sensor module, and adapters for digital communications modes[10] The VX-8 was eventually replaced by the also-discontinued VX-8D(-R/-E).
[11] The also-discontinued VX-8G was yet another model in the family which included a built-in GPS module from the factory, and was intended to be used by the "Devoted APRS user.
