14. VOX GAIN @
This controls sensitivity of the VOX (Voice Operated
Transmit) circuit.
15. VOX DELAY CONTROL @®
The DELAY control adjusts the hold time for VOX or break-in
CW operation. Adjust for individual preference.
16. PHONES JACK ®
The headphones jack allows use of a 4 to 16 ohm
headphone through a 1/4" phone plug. When phones are
used the speaker is disconnected.
17. MIC CONNECTOR @
The four pin connector allows use of a microphone with PTT.
Figure 2-1 shows plug wiring.
18. MODE SWITCH
The mode switch selects type of emission, and TUNE.
TUNE........... This position provides reduced carrier and
shorted key line for transceiver tuning. (Input
power to the final section is reduced to
prevent tube damage during tune-up.)
Frequency is shifted approximately +800Hz
from the USB or CW receive frequency.
This is the actual CW transmit offset. This
feature allows you to Zero-Beat an incoming
CW signal.
Used for CW operation. A high-cut filter is
inserted in the receiver audio circuit to
reduce unwanted noise.
SSB filter selected for WIDE receive
bandwidth.
(NARROW) Used for CW operation with CW
filters YK-88C (500 Hz), YK-88CN (270 Hz),
YG-455C (500 Hz) or YG-455CN (250 Hz),
which are available as optional accessories.
Without an optional CW filter installed, the
pass-bandwidth is the same as in CW.W
CWIW csscvsanas
CWE Nesscccvness :
USB............. Used for upper-sideband operation. Inter-
national Amateur practice dictates the use of
USB on and above the 10 MHz band.
LSB .... . Selects lower-sideband. International
Amateur practice dicates the use of LSB on
and below the 7 MHz band.

19. MIC GAIN CONTROL @
This control adjusts microphone amplifier gain for SSB
operation. Adjust for an on-scale ALC reading on voice
peaks
In the CAL ON position, receive frequency can be calibrated
at 25 kHz intervals using the built-in oscillator.
20. CAR LEVEL CONTROL @)
This controls carrier level during CW operation. Adjust for
approximately 250 mA of plate current.
21. FIX SWITCH
Place this switch ON for fixed channel operation:
(an optional crystal is required. Trio-Kenwood does not
supply these crystals.)
22. MONI (MONITOR) SWITCH @
This delivers a sample of the demodulated transmit IF signal
to the AF for monitoring modulation.
23. RF ATT SWITCH ®
With this switch ON, A 20 dB attenuator is inserted in the
antenna circuit, protecting the RF amplifier and mixer from
overload on strong input signals.
24. DIGITAL DISPLAY
The digital display indicates operating frequency to the
nearest 100 Hz.
25. ANALOG DIAL SCALE
The mono-scale permits direct analog frequency readout
over the O to 500 kHz range, graduated at 1-kHz intervals.
Operating frequency equals the dial (in kHz) plus the BAND
switch frequency (in MHz). An additional 50 kHz both
above and below the 500 kHz range is also covered.
26. MAIN TUNING
27. LOAD CONTROL @
This controls the loading of the network between the final
section and the antenna. Adjustment is described in Section
4.
28. PLATE CONTROL @
This controls the plate tuning of the final amplifiers. Ca-
libration is approximate.
