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. FEATURES 2 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 Watt) Power Settings—let you select the best power setting for 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 Repeater Offsets —let you program different repeater offset frequencies for each memory, and a default repeater offset for manually-tuned frequencies. Subaudible Tone Transmit and Receive (CTCSS) —transmits the subaudible tones required to 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.
