ICF-5800 L / Captain 77
überarbeitet am 23.10.2010
In the seventies, Sony presented several shortwave travel radios with a
"military" style appearence and a typical square cabinet, the ICF-5500M / Captain 55
as well as it's bigger brother ICF-5800 / Captain 77 were both single conversion
analog receivers. The ICF-5900W had a similarly shaped cabinet but a completely
different circuitry and was a double conversion superhet with a crystal marker
and a linear interpolation dial.
The Sony ICF-5800 / Captain 77 is one of the typical multi band receivers with a somewhat "Army look"
of the seventies, it's the "older brother" of the simpler ICF-5500 / Captain 55.
As found in other early Sony radios, the layout of the front panel controls
is somewhat extraordinary: The speaker grill is located in the bottom part of the front panel,
in the left top part of it, You find a big rotary control to adjust the volume, two smaller controls
for bass and treble and two switches, one for dial illumination and the other one acting as
main ON/OFF switch.
In the right upper corner of the front panel, You find the analog signal
strength meter, just below two switches to activate AFC in the FM band and
the DX/LOCAL switch on AM and the rotary band selector.
At the top face of the receiver, You find the telescopic antenna that pops
out of the cabinet when You press the antenna release button.
The Captain 77 designed as a travel portable is nowadays too bulky to be taken on airplane trips, but it still finds good use as a home radio in the kitchen or workshop or in a holiday appartment. FM and mediumwave performance is good, shortwave reception is mediocre: You can of course listen to strong signals on the shortwave bands but the dial marks are too coarse to identify a frequency correctly or to tune in to a station on a certain known frequency and to be more or less sure, You monitor the correct frequency, if the signal is strong enough. There is no BFO to monitor CW or single sideband amateur radio communications.
