Operating Manual

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 offset tone frequency will indicate at the frequency display area of the display while this button is pressed.

9. [BK-IN] Switch

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

10. [KEYER] Switch

This button toggles the internal CW keyer on and off. While activated, the “KEYER” icon appears in the display. The Keyer sending speed is adjusted via the front panel’s [SPEED] knob and the CW Hang Time is adjusted via the Menu item “044 A1A DELAY”.

11. [AGC] Switch

This button selects the AGC characteristics for the receiver. 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).

Advice:

The Attenuator may be used in conjunction with the [IPO] button to provide two stages of signal reduction when an extremely strong signal is being received.

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 overloaded.

12. 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.

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.
