29. DRIVE CONTROL
This control tunes the plate tank circuit of the 12BY7A
driver as well as the receiver's antenna and mixer coils. In
receive the DRIVE control is tuned for maximum sensitivity
(maximum S-meter deflection), and in transmit for a
maximum on-scale ALC reading. These points occur
concurrently. Tuning for one also achieves the other.
30. RIT/XIT INDICATOR LED
This indicator will light when the RIT switch (44) or XIT
switch (43) is ON.
31. RIT/XIT CONTROL
This control allows the receive frequency, transmit frequency
or both to be shifted without using the main tuning control.
With the RIT switch (44) ON, the RIT circuit is activated to
shift only the receive frequency.
With the XIT switch (43) ON, the XIT circuit is activated to
shift only the transmit frequency.
When both switches are ON, both frequencies are shifted.
The center (O) position equals no shift.
32. BAND SWITCH
The 10-position switch selects all Amateur bands from 1.8
to 29.7 MHz. To select the 28.5 or 29.5 MHz bands, push
the +0.5 switch (33) ON.
Use the 10 MHz band for WWV reception.
An AUX receive band is also available.
Coilpack (Receiver front-end) and PLL components must be
installed and aligned for the specific receive frequency range
desired.
33. +0.5 SWITCH
This switch is used in conjunction with the bandswitch (32.).
Depress the switch with the bandswitch set to "28", and the
transceiver will operate in the 28.5 MHz band. When the
bandswitch is set to 29", the transceiver will operate in the
29.5 MHz band. This switch has no function at any other
bandswitch position.
34. RF GAIN ®
This adjusts receiver RF amplifier gain. Turn fully clockwise
for maximum gain and a correct S-meter reading.
35. AF GAIN ®
This adjusts receiver audio level.
clockwise.
Volume increases
36. POWER SWITCH
This switches all power to the transceiver.
37. HEATER SWITCH
This switch turns the three transmitting tube filaments ON.
38. VBT CONTROL ®
The VBT (Variable Bandwidth Tuning) continuously adjusts
the IF Filter bandwidth to eliminate radio interference. For
normal operation, this control may be left fully clockwise
(NORMAL Position).
39. TONE CONTROL ®
This adjusts the audio tone quality of received signals.
Adjust as desired.
40. IF SHIFT CONTROL ®
42. NOTCH SWITCH ®
This switch controls the NOTCH
circuit and indicator.
43. XIT SWITCH @
This push switch activates the XIT (Transmit Incremental
Tuning) circuit and the XIT indicator. By adjusting the XIT
control, the VFO transmit frequency can be varied +2 kHz
without changing the receive frequency.
44. RIT SWITCH ®
This push switch activates the RIT (Receiver Incremental
Tuning) circuit, and the RIT indicator. By adjusting the RIT
control, the VFO
receive frequency can be varied +2 kHz,
without changing the transmit frequency.
If both switches are ON, both the transmit and receive
frequencies will shift simultaneously.
