Receiving Transmissions
To receive a transmission, turn on the HTX-242, adjust the volume
and squelch, and tune to the frequency you want to monitor. The
HTX-242 displays
BUSY , and the signal-strength indicator shows
the relative signal strength when it receives a signal.
Note: If BUSY appears but you hear nothing from the speaker, be
sure the DTMF page and tone-squelch features are turned off and
SQUELCH is set correctly. To turn off DTMF page, press DTMF once.
To turn off tone squelch, press T-SQL until neither T nor T-SQL
appears on the display. See “Activating Subaudible Tone Transmit
and Squelch” on Page 37.
Transmitting
1. Select the desired frequency.
Note: If you select a repeater frequency, the HTX-242 dis-
plays
+ or – to show the offset direction. To operate with no
offset (simplex) on that frequency, press SHIFT until neither +
nor – appears.
2. Press LOW so LOW appears on the display. This selects the
low power (10 watt) setting.
3. Press the push-to-talk button (PTT) on the side of the micro-
phone to transmit. The signal strength meter shows half-
scale for low power (or full-scale for high power). Release PTT
to listen for a reply.
Caution: It is illegal to transmit if you do not have a Technician Class (or
higher) license issued by the FCC.
Notes:
• If the other party advises you to improve your signal, press LOW .
HIGH appears on the display, and the HTX-242 transmits at high
power (about 45 watts). To return to low power, press LOW again.
• If you try to transmit outside the permitted range, the HTX-242 dis-
plays
tF Err and beeps twice.
