Note: When the Automatic Antenna tuner is tuning itself, a signal is being transmitted.
Therefore, be absolutely certain that an antenna or dummy load is connected to the
selected antenna jack before pressing and holding in the [TUNE] button to start
antenna tuning.
6. ANTTENA Select Switch
[1/2]: pressing this selects either the ANT 1 or 2 jack on the rear panel, and allows
convenient antenna switching at the press of button. The selected antenna jack is
indicated at the upper right corner of the display.
[RX]: normally, the antenna connected to the ANT 1 or 2 jack is used for receive (and
always used for transmit). When this switch is pressed, an antenna connected to the
RX ANT is used during receive.
7. PHONES Jack
A 1/4-inch, 3-contact jack accepts either monaural or stereo headphones with 2- or
3-contact plugs. When a plug is inserted, the loudspeaker is disabled. With stereo
headphones such as the optional YH-77STA, you can monitor both Main (VFO-A) and
Sub (VFO-B) receiver channels at the same time during Dual Receive operation.
Note: When wearing headphones, we recommend that you turn the AF Gain levels
down to their lowest settings before turning power on, to minimize the impact on your
hearing caused by audio “pops” during switch-on.
8. KEY Jack
This 1/4-inch, 3-contact jack accepts a CW key or keyer paddles (for the built-in
electronic keyer), or output from an external electronic keyer. Pinout is shown on page
xx. Key up voltage is 5 V, and key down current is 1 mA. This jack may be configured
for keyer, “Bug,” “straight key,” or computer keying interface operation via Menu item
“051 A1A F-TYPE” (see page xx). There is another jack with the same name on the rear
panel, and it may be configured independently for Internal Keyer or
pseudo-straight-key operation.
Note: You cannot use a 2-contact plug in this jack (to do so produces a constant “key
down” condition).
9. Microphone Connector
This 8-pin jack accepts input from a microphone utilizing a traditional YAESU
HF-transceiver pinout.
