13. [METER] Switch
This button determines the function of the meter during transmission.
Press this button to change the meter function in the transmit mode as follows:
ALC  SWR  ID  VDD  COMP  ALC ……
ALC: Indicates the relative ALC voltage.
SWR: Indicates the Standing Wave Ratio (Forward: Reflected).
ID: Indicates the final amplifier drain current.
VDD: Indicates the final amplifier drain voltage.
COMP: Indicates the speech compressor level (SSB modes only).
14. [MIC GAIN] Knob
This knob adjusts the microphone input level for (non-processed) SSB and AM
transmission.
Advice: If you adjust the [MIC GAIN] knob while speaking in a somewhat louder than
normal voice level, watch the ALC level and adjust the [MIC GAIN] knob so that the
ALC reaches just to the right edge of the ALC scale. Then, when you speak in a more
normal voice level, you’ll be certain not to be over-driving the mic amplifier stage.
15. [SPEED] Knob
This knob adjusts the keying speed of the internal CW keyer (4 ~ 60 WPM). Clockwise
rotation increases the sending speed.
When turning this knob while pressing the [KEYER] button, the frequency display
shows the keying speed.
16. Microphone Connector
This 8-pin jack accepts input from a microphone utilizing a traditional YAESU HF
transceiver pinout.
17. 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 ??. 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 “037 A1A F-TYPE” (see page ??). There is another jack with the same name
on the rear panel, and it may be configured independently for Internal Keyer or
