Yaesu FT-1807 UHF400-470MHz Base Station Radio
FEATURE:
50 Watts Power Output
50 Watts of Solid RF Power with No Cooling Fan Needed! Four selectable power output levels are provided: Watts. The power selection may be stored into memory, allowing you to conserve power while using strong local repeaters.
Large LCD Display
The large 6 digit backlit LCD on the FT-1807 ensure excellent visibility
Loud Audio with Internal Speaker
The FT-1807 packs 3W BIG watts of Loud Audio with its own Internal Speaker for those noisy environments.
Excellent Receiver Performance
The receiver front end features Yaesu's renowned Advanced Track Tuning RF input filtering, which affords outstanding protection from Intermodulation distortion.
CTCSS and DCS Encode/Decode Built In
For easy repeater access, or silent monitoring of busy channels, both CTCSS and DCS (Digital Code Squelch) Encoder/Decoder circuits are built in. CTCSS and DCS configuration data may be stored independently in each memory channel. A "Split Tone" mode also allows operation on systems where CTCSS and DCS are used separately on the repeater uplink/downlink.
Extensive Memory System
The provides a total of 221 memory channels, including 200 "regular" memories, ten pairs of band-limit memories, and an instant-recall "Home" channel you can dedicate to a frequently-used repeater or simplex frequency. Memories can store repeater shift information, CTCSS/DCS data, power output level, scanning status ("Skip"), and Alpha-Numeric labels.
Alpha-Numeric Channel Display
Memory channels may be displayed either with the channel frequency or a personalized Alpha-Numeric label, for easy channel recognition. Up to six letters, characters, or numbers may be used for labeling channels.
WIRES Internet Linking Access Feature
The FT-2900R includes a conveniently-located "Internet" key, for quick access to Internet-linked repeater systems. Internet repeater linking allows you to use your FT-2800M to talk to other Amateurs throughout the world, with outstanding voice signal quality. The "Internet" key may be configured to send either a single DTMF digit, or a DTMF string, for operation on a WIRES™ (Wide-Coverage Internet Repeater Enhancement System) repeater, or on other Internet-linked repeaters using DTMF tone access.
WX Channels with
A special 10-channel Weather Band memory bank is provided in the U. S. Version, allowing quick access to NOAA weather broadcasts. When the 1050-Hz "Severe Weather" alert tone is transmitted, the FT-2900R may be configured to emit an alarm tone to get your attention quickly. With the "Weather Alert" feature enabled, the FT-2800M will scan the ten Weather memories, stopping only if the 1050-Hz tone is received.
MH-48A6J DTMF Direct Access Microphone
The backlit MH-48A6J microphone allows direct keypad frequency entry, or keypad memory channel recall. On transmit, the MH-48A6J allows manual entry of DTMF tones for autopatch use, and the FT-2900R also includes a nine-memory, 16-digit DTMF Autodialer. Four user-programmable "soft" keys on the microphone may be programmed for easy control of a number of different features, and the [A]/[B]/[C]/[D] keys replicate the functions of the keys on the front panel of the transceiver, for maximum convenience while driving.
