VX-7R OPERATING MANUAL 1

The VX-7R is a miniature 3-band FM transceiverwith extensive receive frequency coverage, provid-ing leading-edge features for VHF and UHF two-way amateur communications, along with unmatchedmonitoring capability.

The VX-7Rs small size allows you to take it any-where hiking, skiing, or while walking around town and its operating flexibility brings the user manyavenues of operating enjoyment. Besides 50, 144,and 430 MHz transceive operation, the VX-7R pro-vides 222 MHz QRP (0.3 Watts) transceive opera-tion, receive coverage of the AM (MF) and FMbroadcast bands, HF Shortwave Bands up to 16 MHz,VHF and UHF TV bands, the VHF AM aircraft band,and a wide range of commercial and public safetyfrequencies! Dual In-band Receive (V/V and U/U)lets you keep track of two active frequencies. Andthe optional Barometer pressure Sensor Unit providesreadout of barometric pressure and altitude whilemountain climbing or hiking, and it also generates aWeather Forecast based on measured data.

The transmitter section provides 5 Watts of cleanpower output on the FM operation on the 50 MHz,144 MHz, and 430 MHz bands with the suppliedFNB-80LI Battery Pack, and 0.3 Watts output on222 MHz, and 1 Watt of carrier output for AM op-eration on 50 MHz. Both CTCSS and DCS tone sig-naling formats are
