The crystal controlled circuitry provides accurate and stable frequency selection, making it an ideal choice for your amateur communications needs. Note: 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. See "Introduction to Amateur Radio" on Page 7 for more information. [. . . ] Press to store the settings. Use with the FUNC + Key to: Lock the controls (except PTT, , VOL, and SQ). Press again to unlock the controls. PTT (Push To Talk) Swap the input and output frequencies for repeater operations. 21 19-1102RPO. fm Page 22 Friday, June 25, 1999 11:17 AM A QUICK LOOK AT THE DISPLAY 1 2 3 4 5 6 7 8 9 10 11 17 16 15 14 13 12 1. CALL: appears when tone squelch is on and the radio receives a matching tone. BAT: appears when you turn on the radio -- the signal strength meter then indicates the battery strength. Bars show remaining battery power when MO and PTT switch are held down at the same time. 9. : keypad control disabled to prevent accidentally changing a setting. 15. ­ indicates a negative repeater offset. 22 19-1102RPO. fm Page 23 Friday, June 25, 1999 11:17 AM OPERATION TURNING ON THE HTX-200 To turn on the HTX-200, rotate VOL/OFF clockwise until it clicks. Then HELLO appears for about 2 seconds and the last used frequency appears. SELECTING FREQUENCIES (DIRECT TUNING) You tune to the desired frequencies in the VFO (variable frequency oscillator) mode. You can either step to a specific frequency or directly select the frequency. To step to a frequency, repeatedly press or hold down until the display shows the desired frequency. or Note: The HTX-200 steps up or down in increments which you set using the Frequency Step menu option. To directly enter a frequency, press FUNC+ (the second digit from the left flashes), then press or to change the number. Repeat this to select each number of the desired frequency, then press PTT to store the selection. Note: The HTX-200 is preset to receive frequencies between 136 and 174 MHz, and transmit between 144 to 148 MHz. To expand the frequency coverage, see "Changing the Transmit Frequency Range" on Page 38. 23 19-1102RPO. fm Page 24 Friday, June 25, 1999 11:17 AM RECEIVING TRANSMISSIONS Follow these steps to receive standard transmissions. With the radio on, rotate SQ counterclockwise until you hear a hissing sound. Notes: · BUSY appears when the HTX-200 receives a standard transmission or if the squelch is open. The inner control is VOL (volume) and power on/off, while the outer control is SQ (squelch). · If the HTX-200 picks up unwanted, weak transmissions, rotate SQ clockwise to prevent the squelch from opening for these transmissions. Set VOL/OFF to a comfortable listening level. TEMPORARILY OPENING SQUELCH If you use the Tone Squelch (CTCSS) feature, you might not hear a transmission on the current frequency. To temporarily open the squelch so you can hear all transmissions on the frequency, hold down MO. To resume normal operation, release MO. 24 19-1102RPO. fm Page 25 Friday, June 25, 1999 11:17 AM TRANSMITTING There are two basic types of communication possible with this transceiver: radio-direct-to-radio (simplex) or radio-to repeaterto radio (duplex). Duplex operation uses one frequency to transmit and another to receive.
