<P class=head4><STRONG>Switch to SSB for more talk power ... less fade &
interference with this SSB ADAPTER</STRONG> </P>
<P>Designed as a compatible plug-in adapter unit for the TX-1 "Apache"
transmitter, the SB-10 allows operation on single sideband for increased
versatility. This adapter will also be of interest to amateurs now operating
strictly AM or CW with other transmitters such as the Heathkit DX-100. By
making a few simple circuit modifications, most modern transmitters can be
used utilizing all existing RF circuitry. Extremely simple to operate and
tune, the adapter employs the phasing method of generating a single sideband
signal, thus allowing operation entirely on fundamental frequencies. The
critical audio phase shift network is supplied completely preassembled and
wired in a sealed plug-in unit. Also featured are single-knob bandswitching,
an easy-to-read panel meter that indicates relative-power output to aid in
tuning and built-in electronic voice control with anti-trip circuit which
allows duplex operation but prevents receiver output from turning on the
transmitter during listening periods. RF excitation from the transmitter is
required for the adapter to provide an SSB signal which is then fed to the
transmitter final for amplification.</P>
<P><STRONG>Specifications—Power output:</STRONG> 10 watts P.E.P. (peak
envelope power). <STRONG>Power input:</STRONG> Less than 3 watts of RF at the
fundamental operating frequency required. <STRONG>Output:</STRONG> Pi network,
low impedance, coaxial. <STRONG>Input:</STRONG> Low impedance, coaxial.
<STRONG>Band coverage:</STRONG> 80, 40, 20, 15, 10 meters.
<STRONG>Circuitry</STRONG> Phasing method of SSB signal generation is employed
with voice control and anti-trip action built into the audio circuit. <FONT
color=#ff0000><STRONG>Power requirements:</STRONG> 350 VDC @ 85 ma, 6.4 VAC @
3.5 amp.</FONT> <STRONG>Meter:</STRONG> 2½", 200 ua movement, indicates
carrier null and relative power output. <STRONG>Cabinet size:</STRONG> 10" H x
6¾" W x 13" D.</P></DIV>
