Loud Audio with Internal Speaker

The FT-1900R packs 3W BIG watts of Loud Audo with its own Internal Speaker for those noisy environments.

Extended Receiver Coverage

The FT-1900R provides receiver coverage of 136-174 MHz, so you can listen in on a wide variety of commercial, military, public safety, and marine communications.

Illuminated Microphone with Keyboard Frequency Entry

The supplied MH-48a6j DTMF Microphone is illuminated for eas of nighttime use, and you may enter operating frequencies directly from the keypad. What’s more, memory channels may also be recalled directly via the keypad.

200 Memory channels with Alpha-numeric Labeling

The FT-1900′s extensive memory system includes 200 regular memories, ten pairs of band-limit memories, 8 memory banks,and a one-touch “Home” channel. Memory channels store repeater offset information, as well as CTCSS or DCS data, and can have a six-character label appended, for quick channel recognition. And the memories may be allocated into as many as eight memory banks, for more efficient scanning.

Dedicated 10-channel NOAA Weather Broadcast Channel Bank (U.S. version)

Included in the FT-1900r is a dedicated, quick-access memory bank that contains the ten standard NOAA Weather Information Channels, so you can keep track of weather conditions expected for your area.

Programmable

Four user-programmable “soft” keys are provided on the MH-48a6j microphone, allowing you to bring often-used Menu items, or front panel key functions, to your fingertips.

Built-in CTCSS and DCS Encoder/Decoder Circuits

The FT-1900R includes both CTCSS and DCS Encoder/Decoder circuitry, with Reverse CTCSS Decoding also available, to mute your receiver when a particular tone is received (instead of opening your squelch). And you can encode CTCSS and decode DCS, or vice versa, too, if your application requires it.

Adjustable Mic Gain and Wide/Narrow Deviation and RX Bandwidth

The microphone gain for the FT-1900R’s transmitter is adjustable, so you can optimize it for your voice level as well as background noise in your operating location. And for operation in crowded channel environments, the TX deviation and RX bandwidth may both be reduced via the Menu.

Automatic Repeater Shift (ARS), Automatic Power-Off (APO), and BCLO (Busy Channel Lock-Out)

ARS: Automatically selects the typical repeater shift used in your country, based on the current operating frequency.

APO: Automatically turns power off after a user-defined time period, to prevent you from running down your car battery if you forget to turn your rig off.

BCLO: Prevents you from transmitting on an occupied frequency (especially valuable during Tone Squelch or DCS operation).

CW Trainer

You can practice your Morse Code recognition, using this novel trainer that sends you five-character code groups, with variable speed and instant feedback as to the correct characters sent to you.

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 FT-2900R 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-2900R 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. For more information on WIRES™, please visit Yaesu Web site (www.yaesu.com), or send an e-mail to WIRES@vxstdusa.com.

WX Channels

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-2900R 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.
