TUNING METER RE-CALIBRATION

The multi-function meter offers either flashing single or dual segments to indicate properly tuned CW or FSK (RTTY/PKT) stations. An explanation of tuning indica- tions is on page 42.

CW TUNING

From the factory, the single CW tuning segment is calibrated (centered) for the default CW Pitch setting of 700 Hz. If you change the CW Pitch (page 56) to other than 700 Hz, you should re-calibrate the meter so that station center-tuning will match the new CW Pitch. Calibration is a simple process, and only requires a small Phillips screwdriver:

CW Tuning Meter Calibration

(after CW Pitch adjustment)

rOpen the access panel on the transceiver top case to expose the ALC Unit.

rAfter setting the desired CW Pitch, press the [SPOT] button to toggle the CW spot tone (which matches the CW Pitch) on. Use a small screwdriver to slowly turn CW control in the top access panel so the cen- ter meter tuning segment turns on.

rThis completes the calibration for CW tuning; re- place the panel, and turn off the spot tone.

PACKET TUNING

The dual packet tuning segments are calibrated (centered) to the default 200-Hz shift tones used for 300-baud HF packet. These tones use a mark/space pair of 2025/2225 Hz. If you change the default PKT tones (menu selection 6-5) to other than 2025/2225 Hz, you should re-calibrate the meter so that mark/space tuning segments will match the new tone pair:

PKT Tuning Meter Calibration

(after changing PKT Tones)

rOpen the access panel on the transceiver top case to expose the ALC Unit.

rAfter selecting the desired tone pair, recall menu selection 4-2, and select “bEEP-tun” using the SUB VFO-Bknob.

rRotate the MAIN VFO-Aknob to display (and oscil- late) the center frequency of the mark/space tone pair you are using (1170 Hz, 1700 Hz, 2125 Hz, 2210 Hz - see page 58).

rUse a small screwdriver to slowly turn PKT control in the top access panel so the center meter tuning segment turns on.

This completes the PKT calibration, replace the panel, and turn off the beep tone.

RTTY TUNING

RTTY tuning segments are calibrated (centered) for default 170-Hz shift, using a mark/space pair of 2125/ 2295 Hz. If you change the default RTTY shift (menu selection 6-0) to other than 170 Hz, you should re-cali- brate the meter so that mark/space tuning segments match the new tone pair:

RTTY Tuning Meter Calibration

(after changing RTTY Shift)

rOpen the access panel on the transceiver top case to expose the ALC Unit.

rAfter setting the desired RTTY shift, recall menu selection 4-2, and select “bEEP-tun” using the SUB VFO-Btuning knob.

rRotate the MAIN VFO-Aknob to display (and oscil- late) the center frequency of the mark/space tone pair for the shift you are using (170 Hz = 2210 Hz, 425 Hz = 2125 Hz, 850 Hz = 2550 Hz).

rUse a small screwdriver to slowly turn RTTY con- trol in the top access panel so the center meter tun- ing segment turns on.

This completes the RTTY calibration, replace the panel, and turn off the beep tone.

Caution!

Do not adjust TUM-Mcontrol in the top access panel by mistake, as this will adversely affect meter tuning indication, requiring factory re-alignment!
