HTX-242 Two-Meter Mobile Transceiver
(190-1126) Features FaxBack Doc. #19151
Your HTX-242 Two-Meter Mobile Transceiver is an exciting addition to Radio
Shack's growing line of high-quality amateur radio equipment. It offers
some of the most advanced, and most requested, features available in a
mobile transceiver. Be sure to read this entire manual to understand how
to use all the radio's features.
You must have a Technician Class or higher Amateur Radio Operator's
License and a call sign issued by the FCC to legally transmit using this
transceiver. Transmitting without a license carries heavy penalties.
Getting a license is easier than ever. Your local Radio Shack store has
training materials for all classes of Amateur Radio Operator.
Auto Memory Store (AMS) - automatically searches for active
frequencies and stores them in memory,
including the appropriate repeater offset.
High (45 Watt) and Low (10 - let you select the best power setting for
Watt) Power Settings effective communications.
True FM Modulation - provides a clear, natural-sounding signal.
41 Memory Channels - hold one calling frequency and 40 standard
frequencies.
Priority Memory Channel 1 - lets you set the HTX-242 to periodically
check the frequency stored in Memory Channel
1 and alert you if there is activity on it.
Individually Programmable - let you program different repeater offset
Repeater Offsets frequencies for each memory, and a default
repeater offset for manually-tuned
frequencies.
Subaudible Tone Transmit and - transmits the subaudible tones required to
Receive (CTCSS). use some repeaters, and also lets you set a
subaudible tone that your transceiver must
receive to open squelch.
DTMF Page with Group Calling - lets you set a sequence of up to seven DTMF
tones that your transceiver must receive to
sound an alert tone and open squelch.
DTMF Transmit and Memory - lets you manually send DTMF tones or send
DTMF sequences of up to 15 digits each from
one of 10 DTMF memories to quickly access
DTMF-access repeaters, autopatches, or other
stations equipped with a DTMF page feature.
Programmable Frequency Step - lets you set the frequency step for tuning
or scanning to 5, 10, 12.5, 20, 25, 50, or
100 kHz.
Extended Band Coverage - receives from 136 to 174 MHz and lets you
extend transmit coverage to include 2-Meter
ham, MARS (Military Amateur Radio Service,)
and CAP (Civil Air Patrol).
Dual VFO (Variable-Frequency - two independent VFOs let you quickly select
Oscillator) and Duplex Modes between two directly-entered frequencies.
You can also use one of the VFOs as a
repeater input frequency and the other as a
repeater output frequency for odd-split
repeaters.
To make this manual as easy to use as possible, we give you several ways
to find information.
Contents - lists all sections in the order they appear in
the manual.
Understanding the Display - lists all display indicators and gives a brief
explanation and notes the sections where the
indicator is fully explained.
Using the Menu - lists the options in the configuration menu and
gives the page numbers where the options are
discussed.
Quick Reference Card - gives brief instructions for most functions.
Type Conventions - make the references to keys and displays easier
to find in the text:
Keys are bold. For example, VFO.
When a key has more than one marking (for
example, DTMF and ALM refer to the same key),
we refer to the key by the name appropriate
to the task.
Where you are instructed to press two keys at
once, the keys are separated by a + symbol.
For example, F+DTMF.
Text and symbols that appear on the
transceiver's display appear in a special
typeface. For example, 144.940.
