  TW 100 F

The " TW 100 F Fly Away Transceiver " was built by Transworld (USA).
It was (for example) used by the US State Department.

It is a compact, fully transistorized, synthesizer- operated SSB- transceiver for the frequency range of 1.6 to 30 MHz; channel spacing is 100 Hz.

The transceiver is built into an aluminium suitcase, and secured by four rubber shock-absorbers. the suitcase even fits under the seat of an aeroplane.

It has 100 memory channels, 2 to 98 channels can be scanned.
the output power is 10 or 125 W.

All operational elements are on the front plate; the frequency (6 digits) is entered by keyboard.

The power supply is 12V DC or 115, 230 or 240V AC at 50, 60 or 400 Hz. At DC the voltage never should drop below 11V.

The circuits are contained in 6 containers, connected by SMA plugs (see picture gallery).

The built in ATU is operated by hand, and a variety of rod antennas, wire antennas, dipoles and other 50-ohm-antennas can be matched.

Protection circuits against antenna mismatch are built in, like open or short circuit antenna output.

The accessories are contained in two plastic bags inside the suitcase. A handset, a wire antenna, connecting cables, adapters for foreign power supplies are part of the accessories. The radio can go on air within minutes.

Usually the radio is operated inside the suitcase; it can be taken out by loosening four wingnuts on the shock absorbers.

Optional accessories (not present) are:

  • TW5201 remote control
  • TW5800 telephone coupler
  • TW5500 RTTY terminal
