Band Switch; Vfo Operation - Kenwood TS-930S Instruction Manual

WM KEY CONNECTION (Fig. 5-6)
Your key should be connected as illustrated in Fig. 5-6. Use
shielded fine from the key to transceiver.
NOTE
When using an electronic keyer, set polarity of the keyer for
positive keying.
CW break-in
During CW operation, the transceiver will automatically
enter transmission mode when the key is depress, if the
VOX switch is turned on in the standby mode.
{1) Semi break-in
(2) Full break-in
Set-up as for Semi break-in, except place the Semi/Full
switch to Full.
Full break-in capability allows the DX or contest operator to
respond mode quickly to the calling station. To the RAG
chewer, it allows a mode natural conversation.
CAUTION:
Fuil break-in operation is not possible in combination with the
TL-922{A) linear amplifier.
10. Final protection
The TS-930S incorporates four final stage transistor pro-
tection circuits. Two protection circuits monitor antenna
VSWR and final amplifier current and automatically reduce
output power, if a fault occurs. A third circuit monitors the
final heat sink temperature and controls the cooling fan
when the temperature elevates to 50°C. This is sufficient
to coot the heat sink under normal circumstances. The
fourth protection circuit operates if the heat sink
temperature has exceeded safe-limits because of poor con-
vection cooling (above 75~80°C). Transmission will
automatically be locked-out and the transceiver will return
to reception mode. .
When the temperature protection circuit is on the cooling fan
operates at increases speed for faster cooling. When the
heat sink temperature falls below to 65 ~ 70°C, this protec-
tion circuit resets and the transmitter is again enabled.
The fan will stop when the heat sink returns to 45°C.

{2} 1-MHz step switches
Depress the UP or DOWN switches and the frequency will
increase or decrease in 1 MHz steps at each key press.

(1) FUNCTION switch
This sefects VFO A, VFO B, VFO A-R, or VFO B-R. In the
VFO A-R and VFO B-R modes, either split frequency (in the
same band), or cross band operation is available. This
system closely approximates the feel of operating a
separate ceceiver and transmitter. The FUNCTION switch
selects working VFOs, as summarized above.
In addition, the unused VFO may be used as a memory.
For exemple, when waiting for a scheduled contact, store
the schedule frequency in one VFO and continue to operate
or search on the other VFO until your scheduled contact.
(2) A=B switch
Use this switch to equalize the frequency of the idle VFO ta
that of the working VFO.
{3} D. LOCK switch
The D. LOCK switch permits electrically locking the fre-
quency of the working VEO. With this switch on, VFO A
and B frequencies will not vary when the tuning contro! or
BAND switch is operated. For convenience, however, the
RIT does operate.
