9-1. PERIPHERAL DEVICES AND
OPTIONS
The following optional accessories are available for more
efficient and enjoyable operation of the TS-940S.
• AT-940 AUTOMATIC ANTENNA TUNER
The TS-940S is available either with or without a built-in
automatic antenna tuner. The tuning range is automatical-
ly pre-selected at band selection. Reflected power and fin-
al stage lc (collector current) are monitored to control the
tuning motors for the lowest SWR.
The tuner covers all amateur bands from 160 through 1 0
meters, including the new WARC bands. Matching capa-
bility is 20 to 150 ohms, unbalanced. The front panel
"AUTO-THRU" switch allows bypassing the tuner, if de-
sired.
• SPEAKER SP-940
The SP-940 is a low-distortion speaker with selectable
frequency response for high intelligibility in any mode.
The frequency response is shaped by selectable built-in
audio filters, which are effective in improving the signal-to-
noise ratio under certain interference conditions, or when
receiving weak signals.

• STATION MONITOR SM-220
Built around a basic 1 0 MHz oscilloscope, the SM-220
station monitor features, in combination with a built-in
two-tone generator, a variety of waveform-observing ca-
pabilities.
In addition the TS-940S provides the capability of "Pan
display" or spectrum analysis of band activity when the
optional BS-8 is used with the SM-220.
