The FT-7900R provides 50 Watts of power on the 144 Mhz band, and 40 Watts on the 430 MHz,

and is designed for simplicity of operation along with high performance in the receiver section.

The FT-7900R is ideal for the active Ham who has a need for simplex, repeater, or FM satellite

operation on both bands, but without the complication of cross-band repeat capability, which

is available on our FT-8800R and FT-8900R models.

NOAA Weather ALert (U.S. Version only)

A special memory bank on the FT-7900R allows instant recall of the ten NOAA Weather frequencies.

What’s more, you can enable a special “Severe Weather Alert” feature that will sound an alarm

when a NOAA station transmits the special alert tone during a severe weather alert broadcast.

Over 1000 Memory Channels

The FT-7900R’s incredible memory channel capacity includes registers for over 1000 channels,

each capable of storing a 6-character Alpha-Numeric label. And the memories may be stored in

any of the 20 available memory groups; a particular memory channel may also be stored in multiple

groups, if desired.

WiRES™ Internet Linking Capability

The FT-7900R’s DTMF signaling capability includes provision for easy access to Yaesu’s WiRES™

(Wide-coverage Internet Repeater Enhancement System) Internet linking nodes, as well as other r

linking systems that require a DTMF string for access.

YSK-7900 Remote Mounting Kit (option)

Using the optional YSK-7900 Separation Kit, which contains both cabling and a bracket for the remote

front panel, you can mount the FT-7900R’s front panel on the vehicle’s dash board, then stow the

radio’s body under the seat or in some other convenient, out-of-the-way location. The cables are

approximately 20 feet (6 m) in length.

One-Touch “Hyper Memory” Operation

Five front panel keys allow complete transceiver configuration status to be stored for convenient

one-touch recall. So you can set up favorite frequencies in each operating band, including the

receive-only bands, then recall them with a single touch of a button!

 High Power Output

Boasting a big 50 Watts of power output on 144 MHz, and 40 Watts on 430 MHz, the FT-7900R also

includes provision for three lower power levels, so you never have to use more power than you really

need. The power level is stored in regular and Hyper Memory registers, too

Wide Receiver Frequency Coverage

The FT-7900R provides receiver coverage from 108 to 520 MHz, and 700 to 999.99 MHz (cellular blocked),

so you have available a wide range of monitoring excitement, including AM Aircraft, Public Safety,

Government, Business, and, of course, Amateur communications. The synthesizer steps appropriate

for the operating band are automatically selected, too!
