REPEATER – 3TRANSMITTING A 1750 Hz TONEMost repeaters in Europe require that a transceivertransmit a 1750 Hz tone. On a TH-D72E, simply pressing[CALL] will transmit this tone. It is also possible toprogram [1750] on the front panel as a [CALL] key fortransmitting the 1750 Hz tone.1 Enter Menu mode and access Menu 162.2 Set it to “1750Hz”.Some repeaters in Europe must receive continuoussignals for a certain period of time, following a 1750 Hztone. This transceiver is also capable of remaining in thetransmit mode for 2 seconds after transmitting a 1750 Hztone.1 Enter Menu mode and access Menu 163.2 Set it to “On”.Note: While remaining in the transmit mode, the transceiver does notcontinuously transmit a 1750 Hz tone.REVERSE FUNCTIONAfter setting a separate receive and transmit frequency,you can exchange these frequencies using the Reversefunction. This allows you to manually check the strengthof signals you receive directly from other stations, whileusing a repeater. If the station’s signal is strong, move toa simplex frequency to continue the contact and free upthe repeater.Press [REV] to turn the Reverse function On or Off• When the Reverse function is On, the “ ” icon will appear onthe display.Note:X If the transmit frequency is outside the allowable transmitfrequency range when using Reverse, pressing [PTT] will causean error tone to sound and transmission will be inhibited.X If the receive frequency is outside the receive frequency rangewhen using Reverse, an error tone will sound and Reverse willnot operate.X The ARO (Automatic Repeater Offset) will not function whenReverse is ON.X You cannot switch Reverse On or Off while transmitting.AUTOMATIC SIMPLEX CHECKER (ASC)While using a repeater, ASC periodically monitors thestrength of signals you receive directly from the otherstations. If the station’s signal is strong enough to allowdirect contact without a repeater, the “ ” icon blinks.Press [REV] (1s) to turn the ASC On.• When the ASC is On, the “ ” icon will appear on the display.• While direct contact is possible, without the use of a repeater,the “ ” icon will begin blinking.• To exit ASC, press [REV].Note:X Pressing [PTT] will cause the “ ” icon to stop blinking.X ASC does not function if you are using simplex operation.X ASC does not function while scanning.X Activating ASC while using Reverse will switch the Reversefunction Off.X If you recall a Memory channel or the Call channel, and thosechannels are set up with the Reverse function switched On, theASC will switch OffX You cannot use ASC when the built-in TNC is turned On.X ASC causes received signals to be momentarily intermitted every3 seconds.TONE FREQUENCY IDThis function scans through all tone frequencies to identifythe incoming tone frequency on a received signal. Youcan use this function to find which tone frequency isrequired by your local repeater.1 Press [TONE] to switch the Tone function On.• The “ ” icon appears on the display.2 Press [F], [TONE] (1s) to run the Tone Frequency IDscan.• Scan starts and “Scanning” blinks on the display.• To reverse the scan direction, turn the Tuningcontrol clockwise ]> (upward scan) orcounterclockwise ]> (downward scan).• To quit the function, press [ESC ].• When the tone frequency is identified, the identifiedfrequency appears on the display and blinks. Press anykey other than [ OK] while the identified frequency isblinking, to resume scanning.3 Press [ OK] to program the identified frequency inplace of the currently set tone frequency.• The Tone function will remain On. You can press [TONE]to switch the Tone function Off.• Press [ESC ] if you do not want to program theidentified frequency.
