FRONT PANEL CONTROLS & SWITCHES

AGC Switch

This button selects the AGC characteristics for the re- ceiver. Available selections are FAST, MID, SLOW, or AUTO, and the “AGC” icon will change according to the AGC characteristics selected.

Press the [AGC] button repeatedly to select the desired receiver-recovery time constant. Press and hold in the [AGC] button for two seconds to disable the AGC (for testing or weak-signal reception).

When the [AGC] button is pressed independently, it applies to the Main band (VFO-A) receiver.

When you press the [B] button, followed by the [AGC] button (within five seconds of pressing the [B] switch), it affects the Sub band (VFO-B) receiver.

ADVICE:

If the AGC receiver-recovery time is set to “Off” by pressing and holding in the [AGC] button, the S-meter will no longer deflect. Additionally, you will likely encounter distortion on stronger signals, as the IF amplifiers and the following stages are probably being over- loaded.

NB Switch

This button turns the IF Noise Blanker on and off. Press this button momentarily to reduce a short-duration pulse noise; the “” icon will appear in the dis- play.

Press and hold in this button for one second to reduce

alonger-duration man-made pulse noise; the “” icon will blink for three seconds, then will appear con- tinuously in the display.

Press this button again to disable the noise blanker; the “” icon will disappear.

ADVICE:

When you press (or press and hold) the [NB] button momentarily, it affects the Main band (VFO-A) re- ceiver. When you press the [B] button, then press (or press and hold in) the [NB] button (within five seconds of pressing the [B] button), it affects the Sub band (VFO-B) receiver.

METER Switch

This control switch determines the function of the meter during transmission.

COMP: Indicates the speech compressor level (SSB mode only).

ALC: Indicates the relative ALC voltage.

PO: Indicates the average power output level.

SWR: Indicates the Standing Wave Ratio (Forward: Reflected).

ID: Indicates the final amplifier drain current.

VDD: Indicates the final amplifier drain voltage.

MONI PROC Knobs

MONI Knob

The inner [MONI] knob adjust the audio level of the transmit RF monitor during transmission (relative to the AF GAIN control), when activated by the [MONI] button.

PROC Knob

The outer [PROC] knob sets the compression (input) level of the transmitter RF Speech Processor in the SSB and AM modes, when activated by the [PROC] but- ton.

BK-IN Switch

This button turns the CW break-in capability on and off. While the CW break-in is activated, the “” icon appears in the display.

SPOT Switch

This button turns on the CW receiver spotting tone; by matching the SPOT tone to that of the incoming CW signal (precisely the same pitch), you will be “zero beating” your transmitted signal on to the frequency of the other station.

The Sub (VFO-B) frequency display will indicate the offset tone frequency when this button is pressed.

SPEED PITCH Knobs

SPEED Knob

The inner [SPEED] 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 Sub (VFO-B) frequency display shows the keying speed.

PITCH Knob

The outer [PITCH] knob selects your preferred CW tone pitch (from 300 ~ 1050 Hz, in 50 Hz increments). The Tx sidetone, receiver IF passband, and display offset from the BFO (carrier) frequency are all affected simultaneously. The Pitch control setting also affects the operation of the CW Tuning Indicator, as the center frequency of the CW Tuning Indicator will follow the setting of this control.

NB SQL Knobs

NB Knob

The inner [NB] knob adjusts the noise blanking level when the (analog) IF noise blanker is activated by pressing the [NB] button.

SQL Knob

The outer [SQL] knob sets the signal level threshold at which the Main (VFO-A) receiver audio is muted, in all modes. It is very useful during local rag-chews, to eliminate noise between incoming transmissions. This control is normally kept fully counter-clockwise (off), except when scanning and during FM operation.
