FT-7900E Dual Band FM Mobile Transceiver
FT-7900E 2 Meter / 70 cm Dual Band FM Transceiver

With Exceptionally Wide Receiver Coverage

The FT-7900E 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-7900E 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-8800E and FT-8900E models.

High Power Output
Boasting a big 50 Watts of power output on 144 MHz, and 40 Watts on 430 MHz, the FT-7900E 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-7900E 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!
Large LCD Display
The large backlit LCD on the FT-7900E ensure excellent visibility
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, and then recall them with a single touch of a button!
Over 1000 Memory Channels
The FT-7900E’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.
YSK-7800 Remote Mounting Kit (option)
Using the optional YSK-7800 Separation Kit, which contains both cabling and a bracket for the remote front panel, you can mount the FT-7900E’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.
WiRES™ Internet Linking Capability
The FT-7900E’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 linking systems that require a DTMF string for access.
Note: Specifications are subject to change without notice, and are guaranteed within the 144 and 430 MHz Amateur Bands only. Frequency ranges will vary according to transceiver version; check with your dealer.
