INTRODUCTION
The TS-830s 1s a dual conversion transceiver using two in-
termediate frequencies, 8.83 MHz and 455 kHz. However.
this differs from transceivers of the 'socalled Colllns type(such
as the TS-520) in that the bandwidth of both intermediate
frequencies IS narrowed for perforrr~ingVBT operation
Therefore, the TS-830s can basically be considered a single
conversion transcelver wlth an 8.83 MHz IF
Operation of the transmitter is opposite In process to the

RECEIVER CIRCUIT
The signal comlng from the antenna is routed through step-
up antenna coil via an RF ATT switch and IF trap. MOS FET
(Q1 3SK73) amplifies this slgnal Approximately 9 dB of
negatlve feedback is applied to -the RF amplifier to reduce
nolse and expand the amplifiers range of linear operation
The signal passes through a buffer amplifier (Q2 2SK125)
and is m~xedwith the PLL VCO output by a balanced mixer
((23, Q4 2SK125) The signal is now converted to the first
lntermedlate frequency, 8.83 MHz. Entering the IF unit, this
signal is amplif~edby Q1 (2SK125),passes through ceramic
filter CF1 and the NB gatlng circult, and is applled to crystal
filter XF1 whose center frequency is 8.83 MHz. The signal
leaving the crystal filter is mixed wlth the VBT local oscillator
output at 8.375 MHz by a balanced mixer (Q2,03 3SK73)
where it IS converted to the second Intermediate frequency,
455 kHz. The signal then passes through ceramic filter CF2
whose center frequency is 455 kHz, and is amplified by 04
(3SK73) It then IS fed to the notch circuit, Q5 through Q7
(2SC1815) After being amplified by Q8 (3SK73), it is
demodulated to an audio srgnal by the product detector
(D20--D23, IN60 X4)
In the AF unit, the audio s~gnal is amplified by Q3
(2SC2240), passes through the AF GAIN control and after
belng arnpllf~edby the power amplif~erQ4 (HA1368R).

Audlo input picked up by the m~crophonecomes to the IF
unit and
IS amplif~edby Q19-21 The input circuit adapts
to any m~crophoneimpedance of from 500 ohms to 50k
ohms. This ampl~f~edoutput
IS converted to a DSB signal by
the balanced modulator D29-32
(1N60 X 4),passes through
buffer
amplifier Q22 (2SK1 9), a 455kHz ceramic filter, and
the output appears as a SSB slgnal This signal passes either
buffer amplifier Q23 (2SC1815), or the speech processor
consisting of Q24, 26, and 27 Then the first transmit mixer
(Q28 3SK73) converts thls to an 8.83 MHz SSB signal
After passing the 8.83 MHz crystal filter and being amplified
by Q29 (3SK73),the signal is applied to the second transmit
mixer in the RF unit. This. double balanced mixer (Q6,
Q7 3SK73), mlxes the slgnal with the PLL VCO output to
convert to the final Transmlt frequency Output is amplif~ed
by the driver tube (V1 12BY7A)and then by the final power
amplifier (two 6146B's) and is applied to the antenna via
a
T-matching network.

Frequency organization of the PLL circult IS shown In Figure
I, the circu~tdiagram in Figure 2, and frequency organlzatlon
in other circuits is summarized in Table 4. Please refer to
Figure 1 when reading the following
description on PLL clr-
cuit operation MIX (3),a double balanced mixer, mlxes the
CAR output wlth the VFO output. MIX (2)wh~choperates in
18 MHz bands and above, mlxes e~ther10 NIHz, In the 14
and 18 MHz bands, or 20 MHz, In the 21, 245, and 28 IW Hz
bands, wlth the output of MIX (3)to generate the
appropriate
frequency needed for each band, as shown In Table 4
This
IS mrxed wlth the VCO output for each band by MIX (1)
to a frequency given In Table 4, whlch IS then routed through
LPF (1
), amplified, and wave-shaped to a dlgltal signal
A
programmable divider divides thls slgnal into a 500 kHz out-
put. This programmable divlder
IS preset, as shown In Table
4, by the BCD signal whlch
IS counter-generated from Infor-
mation comingfrom the band swltch The phase comparator
used
IS a Motorola MC4044P The loop filter IS made of
completely external components to m~n~mizespurtous radia-
tlon Six VCOs cover all bands. If the PLL unlocks for any
reason, it will be detected from the phase comparator out-
put. Th~swill turn off the VCO output to prevent spurious
radiation and, at the same time, the digital d~splaywill be
blanked to Inform the operator of unlock status.

2. VBT and IF SHlFT
VBT (variable ' bandwldth tuning) allows varylng the
bandwidth, operation of whlch is determlned by the 8.83
MHz and 455 kHz filters and by changing the output frequen-
cies of CAR-1 and CAR-2 simultaneously wi-ththe VBT con-
trol Frequency organlzatlon of the VBT and IF SHlFT 1s
shown In F~gure7 Assuming that a signal centered at
140015 MHz 1s received wlthout lF shift or VBT, the VFO
output frequency is 5.5015 MHz. CAR-1 8831 5 kHz, and
the VCO output applied to the first mixer
IS 22.8315 MHz.
The mlxer converts thls to a slgnal whose center frequency 1s
8830 MHz (228315 MHz-140015 MHz=8830 MHz)
The slgnal frequency
IS then converted to 455 mHz by the se-
cond mlxer To help understand VBT operation, assume the
composite bandwldth determlned by fllters XF1 and CF2 1s
2 7 kHz In the normal (unshlfted) state of CAR-1 and -2

When the CAR-2 frequency 1s reduced by 1 kHz uslng the
VBT control and a slgnal centered at 140015 MHz
IS recelv-
ed the CAR 1 and 2 frequencies are as follows
CAR-1 8831
0 kHz (= 8831 5 kHz-0 5 kHz*)
CAR-2 8374
0 kHz (VBT control)
* The system 1s deslgned so that only half the amount of fre-
quency sh~ftapplled to CAR 2
IS applled to CAR-1
Assume the recelved slgnal has a frequency spectrum exten-
ding over 140015 MHz 5 1 35'k~zSlnce CAR-1 output 1s
8831 0 kHz. the VCO output frequency 1s 22 8310MHzand,
therefore the frequency of the flrst IF slgnal
IS 8829 5 kHz -t
1 35 kHz due to a shift of -500 Hz
(22831
0 kHz- 140015 kHz = 8829 5 kHz) Slnce the
freql~encycharacterlstlc of the flrst IF fllter IS 8830

cut In the lower slde band by 500 Hz more than In the nor-
mal state, as

(8829 5 kHz (No 1 IF)-8374.0 kHz (CAR-2) = 455 5 kHz)
Thus rhe second IF slgnal
IS shifted by +500 Hz, and as a
result the upper-s~defrequency components are cut by 500
Hz, as illustrated In(4) The frequency spectrum of the s~gnal
whlch has passed the second IF stage IS 455 5 kHzk850 Hz
and the bandwidth
IS 1 7 kHz If we convert the srgnal fre-
quency to an equlvalen~one a1 the ANT Input, we obtaln
14.0015 MHz+850 Hz In th~scase IF SHIFT operation is
not performed
Example 2
Bandw~d.rh 1 7 kHz
IF SHIFT 500 Hz (poslt~vesh~ft)
I
When the frequency of CAR-2 is lowered by 1 kHz with the
VBT control and that of
CAR- 1 ralsed by 500 Hz wlth the
SHIFT control, the
resulting frequenc~esof CAR-2 and -1 are
CAR-1 88315 kHz(= 88315 kHz--0.5kHz*l+05
kHz"2)
CAR-2 83740 kHz
*I Half the amount of frequency varied by VBT
*2 The amount of frequency rise with IF SHIFT
Let us examine the frequency spectrum of the ANT input
slgnal from the second IF component in Example 1
You
will recall that the center frequency of the second IF
signal component is 455.5 kHz and the upper limit 455.5
kHz+850 Hz
The signal is 455.5 kHz f8374.0 kHz= 8829.5 kHz in the
flrst IF and the lower llmlt 8829.5kHz-850 Hz. As a result.
signal components which have passed an 8830 kHz fllter
and a 455 kHz fllter are the same as In Example 1 But the
VCO output is 22.8315 MHz because CAR-1 which was
8831 0 kHz
111 Exarrlple 1 is 8831 5 kHz in Example 2 Slnce
the converted equrvalent frequency range at the flrst IF is
8829.5 kHzk850 Hz, ~tsequivalent at the ANT Input IS
14.002 MHzk850 Hz.
(22831
5 MHz-8.8295 MHz= 14.002 MHz)
This means that a signal 1 7 kHz In bandwldth
IS received
wlth a shift of + 500 Hz. In other words, the filter
characteristics have been changed appropriately
As you may have noted in Examples 1 and
2, the V.BT and IF
SHIFT controls operate separately Therefore, it IS possrble
to control the bandwidth alone whlle keeping the IF SHIFT
unchanged,or control IF SHIFT while keeping the bandwldth
unchanged

of the null would be broad at 455 kHz. Actually a sharp
notch is provlded by adding an active circuit which applies
posltive feedback to raise the Q. Q5 and 06 (2SC1815Y)

455 kHz SSB signal is clipped and then c0nverte.d to an 8.83
Mliz signal, and then routed through an 8.83 MHz SSB filter

TS-830s (K) AC Voltage conversion
To operate the TS-830s (K) on 240V AC, the power
transformer split
primaries must be rewired from parallel to
series connection
1. Unplug the AC power cable.
2 Remove the bottom cover
3. Remove the jumper wires between the two
4 terminals
and two 120 terminals on the bottom of the power
transformer.
4. Connect the adjacent 120and
4 terminals at the middle
of the transformer. 'This will provide 240V AC operation.
For 220V AC operation, change the wires from 120 to
100 winding.
5. Change the AC fuse from 6A to 4A. Tag the power cord
at the back of the radio to indicatethat the transformer is
strapped for 240V AC, and the powerfuse should be 4A.
and not 6A.
6. Replace .the bottom cover and reconnect power to verify
your work.
