241 2. SECTION 2 OPERATING INSTRUCTIONS OPERATING FEATURES The equipment has several important operating features which provide maximum flexibility, performance and versatility. These features include: 1. 120 memory positions which can each be programmed with a transmit and receive frequency with 25, 20 or 12.5 KHz channel spacing, Tx/Rx CSS tones or DPL codes and a 9-character alphanumeric title. 2 guard channels which can each be programmed with a Rx frequency with 25, 20 or 12.
2.2 OPERATING INSTRUCTIONS {See Figure 2-1} 1. Switch power on by turning the main volume clockwise. Depending how the radio is configured, either the last programmed or last displayed frequency will appear on the screen. The transceiver is now in normal operating mode. 2. Adjust the audio level by adjusting the main and guard volume knobs. 3. Pressing the squelch defeat button will open both receivers to confirm they work. 4. Read the display.
2.3 PROGRAMMING INSTRUCTIONS Tn program one of the 120 memory channels in the TAM-30: Press the FUN key. The display will show the function prompt. Press the PRIG key. The display will show the current receive frequency with a flashing cursor on the second digit {The first digit is always a one < 12>), Type in the desired receive frequency. If you type in a frequency which is not a 2.5 kHz step, the nearest valid frequency will be automatically selected. The cursor will return to the second digit.
2.4 2.5 2.6 PRIORITY SCANNING, SELECTIVE MEMORY CHANNEL SCANNING AND SCAN LISTS Instead of breaking up the 120 channels into blacks for scanning, the TAM-30 software has § Sean lists. Any of the 120 channels can be assigned to any one of more of these § scan lists. This means the channels do not have to be repeated for them to be in more than one block and that you are not limited to the number of channels that you can scan at once, since all 120 channels can be put into any scan list.
2.7 -2.8 2.9 2.12 RECEIVE FREQUENCY SIMPLEX FUNCTION The receive frequency simplex function allows you to quickly change the transmit frequency, when aerating on a split pair mode}, to the receive frequency to allow direct communications. ie/ If you are transmitting on 42.000 MHz and receiving 42.655 MHz, press FUN then UP to transmit on 42.555 MHz. To return to the split pair condition, you must recall the memory channel again. This is quickly done by pressing M.
PROGRAMMING CSS TONELESS CODES CSS tones (PL tones) or Digital DPL codes can be assigned to each memory channel. The guard receiver squelch will operate only on carrier detection, but guard 1 and 2 transmit tones or codes can be programmed. To program a tone/code to a memory channel: 1. Use the M.UP and MIND keys to select the memory channel that you want to assign a CSS tone or DPL code. 2. Press the FUN key then the TONE key.
2.14 PROGRAMMING CSS TONELESS CODES continued 8. Press ENTER. "GZ TONE" appears on the display. Repeat step 3 and press ENTER. 7. The display will now show "RX DP" and the current 3-digit DPL code. If no DPL code is required "000" should be entered. Please note that if a DPL code is to be programmed a CSS tone should not be enabled. 8. Use the keypad to enter the required octal 3-digit DPL (Digital Coded Squelch or DCS) code.
PC MEMORY/PROGRAMMING DOWNLOAD CAPABILITY continued Installation: 1. Insert the floppy disk into drive A and type: A:INSTALL 2. All the files will be copied to your hard drive into a directory called \TIL. Connections: 1. With the PC turned off, plug the 25 pin male 'D' connector into its printer port. 2. Plug the 15 pin 'D' connector into the back of the TAM-30 transceiver. 3. Connect the power wires to the power supply. Running the program: 1.
Edit menu: {continued) 30 product MHz. Keep in mind that the label for the memory channel can only have characters that exist on the TAM-30 unit. These include only capital letters, numbers 0 to 9 and a few other characters. Any other character will show up as a blank on the unit's display. You will then be prompted to enter a receive CSS tone, a transmit CSS tone, a receive DPL code and a transmit DPL code. Although both CSS tones and DPL codes can be programmed simultaneously, this should not be done.

Table 3-2 lists the signals and connections available from the RTFM. Refer to the Antenna Tuner instructions for specific wiring. Power Source Pin 9 supplies + 28 volts and pin 7 provides a power and signal ground to the ATU. Tune Enable Pin 5 activates the ATU during transmit. Active High {+ 28V).
a9 INTERNAL PROGRAMMING AND GUARD ENABLE/DISABLE JUMPER The programming and direct frequency entry modes can be disabled by removing the internal enable/disable jumper strap farm pins 2 and 3 of J15. Removal of this jumper will prevent operation on any frequencies other than those programmed in the 120 memory positions and two guard receiver memory positions.
