ANTENNAS

Two antenna connectors are available for the HF/ 50 MHz band on the TX/ RX unit rear panel {page 16}.

Press [ATT/PRE/ ANT1/2] (1 s) to select ANT 1 or ANT 2.

¥Ò1tANTÓ or ÒANTs2Ó appears to indicate which antenna is selected.

The ANT 1/ ANT 2 setting will automatically be stored in the antenna band memory. Next time you select the same band, the same antenna will be automatically selected.

Note: Connect an external tuner to the ANT 1 connector only, then select ANT 1. The internal antenna tuner will be automatically bypassed when the transceiver is switched ON.

APO (Auto Power OFF)

You can set the transceiver to switch OFF automatically if no keys or controls are pressed or adjusted for a certain period of time. One minute before the transceiver switches OFF, ÒCHECKÓ is output in Morse code.

Press [MENU/ F.LOCK], then turn the MULTI control to access Menu No. 59.

Select the APO time from ÒoFFÓ, Ò60Ó, Ò120Ó, or Ò180Ó minutes.

Note:

◆The APO function works even if the transceiver is scanning.

◆The APO timer starts counting down the timer when no key presses, no control adjustments, and no command (COM connector) sequences are detected.

AUTOMATIC ANTENNA TUNER

As explained in ÒANTENNA CONNECTIONÓ {pages 2, 4}, matching the impedance of the coaxial cable and antenna is important. To adjust the impedance between the antenna and the transceiver, you have the choice of using the internal antenna tuner (TS-480SAT only) or an external antenna tuner. This section describes how to use the internal antenna tuner. For the external antenna tuner, consult the instruction manual that comes with the tuner.

1Select the transmit frequency.

2Press [ATT/PRE/ ANT1/2] (1 s) to select Ò1tANTÓ or ÒANTs2Ó.

¥If the external antenna tuner (AT-300) is connected to the ANT 1 connector, select ANT 2 to use the internal antenna tuner. The internal antenna tuner is automatically bypassed if the external antenna tuner (AT-300) is connected to ANT 1.

3Press [AT] momentarily.

¥ÒATsTÓ appears, indicating that the antenna tuner is in-line (not bypassed).

4Press [AT] (1 s).

¥CW mode is automatically selected and tuning begins.

¥ÒATsTÓ blinks and the LED lights red.

¥To cancel tuning, press [AT] again.

¥If the SWR of the antenna system is extremely high (more than 10:1), an alarm (ÒSWRÓ in Morse code) sounds and the internal antenna tuner is bypassed. Before attempting to tune again, adjust the antenna system to lower the SWR.

5Monitor the display and check that tuning has successfully finished.

¥If the tuning was successful, ÒATsTÓ stops blinking and the red LED turns OFF.

¥If tuning does not finish within approximately 20 seconds, an alarm (Ò5Ó in Morse code) sounds. Press [AT] to stop the alarm and tuning.

¥If you want the transceiver to stay in transmission mode after the tuning completes, access Menu No. 25 and select ÒonÓ.

If you access Menu No. 26 and select ÒonÓ, received signals will also pass through the internal antenna tuner. When this function is ON, ÒRtATÓ appears. This may reduce interference on the receive frequency.

Note:

◆The internal antenna tuner will not tune outside the available transmission frequency limits.

◆Pressing [AT] for more than one second while transmitting, interrupts transmitting and starts tuning.

◆While using CW Full Break-in, the internal antenna tuner will be in-line for both transmission and reception.

◆Tuning automatically turns OFF in approximately 60 seconds. “AT” disappears and the error beeps stop.

◆Tuning may still continue when the SWR meter indicates 1:1. This happens due to the tuning algorithm; this is not a malfunction.

◆Even though the SWR meter shows more than one segment, the internal antenna tuner may not re-tune. This happens because of an SWR calculation algorithm tolerance.

◆If tuning does not finish even though the SWR meter indicates smaller than 3:1, adjust the antenna system to lower the SWR, then attempt to tune again.

◆Tuning may not reach an SWR of 1:1, depending on the transceiver conditions.
