Operating Manual 

General Description 

The 

VX-8R

 is a Dual Receive fourthband FM transceiver with extensive receive 

frequency coverage, providing leading-edge features for VHF and UHF two-way amateur 

communications along with unmatched monitoring capability. 

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

-(Auto-Range Transponder System), which 

“beeps” the user when you move out of communications range with another 

ARTS

TM

-equipped station. 

We appreciate your purchase of the 

VX-8R

, and encourage you to read this manual
