<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>
