The Gibson Girl Radio SCR-578. This radio
was used on B-17 and B-24 bombers and got its name because their narrow
waist reminded people of the young ladies drawn by illustrator Charles
Dana Gibson. The Gibson Girl
radio set was a hand powered emergency transmitter ruggedly designed for
use in a life raft or small boat. Use of the Gibson Girl enabled rescue
crews to locate survivors of ship or aircraft emergencies. The SCR-578
and its accessories were bright yellow-orange in color and the unit
would float if placed in the water.
The Gibson Girl Emergency Transmitter was included with abandon ship
provisions in life rafts. It was also packaged with a parachute so it
could be dropped to survivors in the water. The Gibson Girl is operated
by holding it between the knees while cranking the internal generator by
hand. It can be set to automatically transmit an SOS signal or manual
keying can be used to send a message.
The Gibson Girl design was based on a captured German emergency
transmitter called the Notsender NS2, easily recognizable with the same
hourglass shape. The British designed an improved version, but lacked
the manufacturing capacity. A contract was let to Bendix Aviation for an
American version, the Radio Set SCR-578-A. Bendix began deliveries
in May 1942. The updated AN/CRT-3
became available in 1945. The Gibson Girl transmitters were used by
military and civilian aircraft and ships into the 1960s.
The Gibson Girl Emergency Transmitter was produced in two main
versions:
Radio Set SCR-578 broadcast on a single frequency of 500 kc, for
reaching locally operating ships and aircraft. There were two
versions, SCR-578-A and SCR-578-B.
Radio Set AN/CRT-3 broadcast on 500 kc or 8280 kc frequencies. The
8280 kc signal reached base stations at longer range. Visually
identical to SCR-578.
Some models of the AN/CRT-3 operated at 8364 kc instead of 8280 kc.
All Gibson Girl frequencies are internationally reserved for
distress signals.
The Gibson Girl transmitter can
be operated by untrained personnel, following instructions printed
on the radio's case. To facilitate operations under all conditions,
the full kit of Gibson Girl radio equipment includes:
- Radio Transmitter BC-778-A (SCR-578) or T-74/CRT-3 (for AN/CRT-3)
- Hand Crank GC-18-A to operate the internal generator
- Reel RL-48 inside a front-panel door holds 800 ft. of antenna wire
W-148
- Kite M-277-A, folding metal frame box kite to raise the antenna in
wind
- Balloon M-278-A, for use when wind is insufficient for the kite
- Generator M-315-A, produces hydrogen to inflate the balloon to 4
ft in diameter
- Signal Lamp M-308-A, to communicate locally with rescue crews
- Parachute M-390-A
- Bag BG-109-A (Cylinder bag containing Kite assembly, 2 balloons, 2
hydrogen generators, signal lamp, wire)
- Bag BG-110-A (Cube shape bag containing Gibson Girl radio and
crank with parachute in pouch on top)
Note that
not all these
accessories are included with this set, please look at photos to see
what is specifically included.
The total weight of the radio and all accessories is 33 pounds. The
suffix letters changed as manufacturing developed improvements. For
example, the M-390-A parachute (untreated rayon) was superseded by
the M-390-B (tropicalized nylon). Other changes included packing all
components into a single cube shaped bag BG-155-A for the AN/CRT-3
model.
The balloon was inflated by connecting the hydrogen generator
inflating tube to the balloon, then immersing the hydrogen generator
in water. The chemical reaction that produced the hydrogen also
produced a lot of heat, so caution was required.

Outdoor Pan /Tilt Rotor originally made
for CCTV but would handle a couple of small Yagis for satellite work.
This is new in the original box. The
control box can be found online for about $100.00.
I am asking $150.00 or Best Offer for
the rotor.

THIS IS A KIT - YOU WILL HAVE TO
ASSEMBLE. The kit includes all parts needed to build the project,
including a heavy metal case. The project is based around an Arduino
Nano, which runs a modified version of the K3NG Winkey software. Support
has been added for SO2R and can communicate with logging software
natively as a Winkey device, or using the SO2R Mini Connector. The
connector is a small piece of software that translates your logging
software OTRSP (Open Two Radio Switching Protocol) and Winkey into a
single stream for the device. The hardware and software are fully
published, allowing the end-user to customize the device as they see
fit.
|

Assembly is easy and
quick. From start to finish, the average kit builder should be able to
complete the kit in an hour. Modest skills are required, there are no
surface mount ICs or RF connectors. The kit contains everything needed
to build a functioning unit.

For more technical
users, I2C and Aux buses are available, allowing for inter-device
communication, as well as GPIO, for extra features, like interlocking,
multi-paddle, band data, and antenna outputs, RTTY generation, and more.
There are also pins available for LED indicators of transmitting and
receive status. The SO2R Mini is designed to be an inexpensive, yet
complete and flexible solution for SO2R contesting. Similarly, the SO2RM
can act as a Winkey by itself. This tiny box measures only 10cm long and
5cm tall. All input connectors are 3.5mm TRS jacks. Separate jacks are
provided for all inputs, with paddle and PTT outputs combined on a
common jack, allowing for a stereo splitting cable to be used for most
traditional radios. The SO2R Mini is powered by USB and requires a
computer connected for full functionality. When no power is applied, the
box automatically shifts transmit and receive audio focus to radio one,
although PTT and CW signals are not passed. If the user desires the
ability to forgo the computer, the SO2R Mini can be expanded to support
transmit and receive control switches and a potentiometer for CW speed
control. These features are supported on the circuit board and in
software. Just add your own pot and switches. |
