6.6 ANALOG DIAL ADJUSTMENT
1. Turn the main dial fully CCW. The red cursor should line
up with the VFO start mark on the sub-dial. If it does
not, remove the main knob (2mm allen), loosen and line
the 12mm nut up the scale start point to the red cursor.
2. Turn the main knob to 50 kHz analog. Adjust the
aluminum slip sub-dial to line up with any one of the
larger black dial marks.
3. Note the digital error. If it is MORE than 2 kHz adjust
the VFO trimmer cap TC1 (Front under the seal tape) to
exactly 50.0 on the digital readout.
4. Turn the main knob to 450 analog. If the digital error is
less than 2 kHz it is in spec. If the digital error is
greater, proceed:
For instance if the digital error is 14.454.0 (plus 4 kHz),
multiply the error times 4 (16 kHz) and adjust the VFO
timmer cap to the desired frequency (14.450.0) LESS
the error, or 14.434.0. Next adjust the VFO inductor L3
(Center under the seal tape) back up to the desired
frequency of 14.450.0.
5. If the error in step 4 was in the minus direction, reverse
the direction of the correction adjustment in step 4.
6. VFO linearity final check: The digital readout and
analog dial should agree to within +2 kHz at every 100
kHz dial point.
6.7 OPERATION ON 220 OR 240V AC
To operate the TS-830S 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 0 terminals
and two 120 terminals on the bottom of the power
transformer.
4. Connect the adjacent 120 and 0 terminals at the middle
of the transformer. This will provide 240V AC
operation.
For 220V AC operation, connect the adjacent 120 and
O terminals, and move the white lead and Bypass,
capacitors from the 120 terminal to the 100 terminal.
5. Change the AC fuse from 6A to 4A. Tag the power cord
at the back of the radio to indicate that the transformer
is strapped for 240V AC, and the power fuse should be
4A, and not 6A.
6. Replace the bottom cover and reconnect power to verify
your work.
