Operating Manual

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
