The VX-8R’s small size allows you to take it anywhere - hiking, skiing, or while walking
around town, and its operating flexibility brings the user many avenues of operating
enjoyment. Besides 50, 144, (225MHz) and 430 MHz transceive operation, the VX-8R
provides receive coverage of the AM (MF) and FM broadcast bands, HF Shortwave Bands
up to 30 MHz, VHF and UHF TV bands, the VHF AM aircraft band, and a wide range of
commercial and public safety frequencies! And the optional Barometer pressure Sensor Unit
provides readout of barometric pressure and altitude while mountain climbing or hiking.
The transmitter section provides 5 Watts of clean power output on the FM operation on
the 50 MHz, 144 MHz, and 430 MHz bands with the supplied FNB-101LI Battery Pack, and
5 Watts output on 145MHz and 430 MHz, （1.5 Watts output on 225MHz） also 1.0 Watts
output on AM operation on 50 MHz. A wide variety of tone signaling formats are built into the
VX-8R, in addition to Yaesu’s exclusive ARTS
TM
