FT-2400H Features
The FT-2400H is a special versión of Yaesu's top-of-the-line professional grade
commercial land mobile transceivers, intended for 2-meter FM operation in the amateur
radio service.
With its compartmentalized one-piece die-cast chassis, the FT-2400H provides 3-step
user-selectable power output up to 50 watts easily without forced cooling. Backlighting
for the large LCD (display), knobs and major but-tons is automatically controlled by a
photosen-sor, and the less-used buttons have a flip-down protective cover.
The thirty-one freely tunable memories can each be programmed with a 4-character chan-
nel ñame, which can then be displayed in place of frequency, as desired. Each memory
offers complete programmability and scanning func-tions, such as independent tx/rx
frequencies, independent repeater offset and CTCSS tone, programmable sean limits,
selectable sean resume modes and memory skip, priority moni-toring and a 1-touch
instant-recall CALL channel. Channel steps are user-selectable from 5 to 50 kHz, and
Automatic Repeater Shift can set standard repeater shifts when you tune to a repeater
subband. A 1750-Hz tone gener-ator is included in European versions.
A 38-tone programmable CTCSS encoder is built-in as standard, and the FTS-17A
CTCSS decoder unit can be installed to provide tone squelched prívate channels and a
CTCSS paging bell feature to sound a paging alert tone when the tone squelch opens.
Revolutionary DTMF (Dual-Tone, Multi-Fre-quency) -based selective calling and prívate
paging capabilities can be easily added with the optional FRC-6, controlled entirely from
the front panel. You can select any of 999 3-digit ID codes for your transceiver, and then
have your receiver stay quiet until your code is received (from any standard DTMF-
equipped transceiver). When a cali is received, the FT-2400H displays the calle r's code,
and a paging beeper can be set to sound and even to respond to the cali automatically.
Seven DTMF code memories store your ID plus those of six other frequently-called
stations or groups you wish to monitor.
Please read this manual carefully to become familiar with the FT-2400H.
