In late 1988, Sony the successor of the analog double conversion shortwave
portable ICF-7600A vor.
The Sony ICF-7601 has a similar appearence and dimensions to the other radios
from the 7600 series, and adds even one model designation more to the list
to confound the collector or consumer. The receiver covers nine spread shortwave
|ICF - 7601
||International version, tropical bands 120 - 75 m
|ICF - 7601L
||European version covering the longwave - band
Analog dial, around 20 kHz
AM, FM (VHF)
FM, LW, MW, nine SW bands (tropical band, 60, 49, 41, 31, 25, 19, 16, 13 m band)
Selectivity -6 dB/ -60 dB
The Sony ICF-7601 is 120 x 190 x 32 mm wide and has dimensions very similar to
those of it's predecessors. The main frontpanel layout has remained nearly the
same, the mechanic frequency range pushbuttons have been replaced by electronic
keys, but the set still comes with a coloured OFF pushbutton.
The left part of the receiver front is taken by the speaker grille.
Most of the right half is taken by the dial window with it's vertical frequency
dials of the spread 60, 49, 41, 31, 25, 21, 19, 16 and 13 m shortwave bands, the dials for
mediumwaves and the FM broadcast band are printed on the cabinet. The leftmost dial
ist used as longwave dial on the European and as 120 - 75 m tropical bands dial
on the international version of the radio. All meter band bumbers are printed
in a grey - blue colour and are quite difficult to read, specially when to light
is ambient. The mechanical indicator for the selected shortwave band below the dial
is in the same colour and nearly as difficult to be identified.
Below the dials,
You find the sliding switch to select one of the shortwave bands and four pushbuttons,
which act as bandswitches for LW, SW, MW and FM, a turquoise - greenish little pushbutton with a
is used to turn off the receiver. An additional small sliding switch HOLD can be
used to prevent the electronic pushbuttons from switching on the radio during travel.
You find the sliding control volume and the tone switch have been rearranged and
are located at receiver's right small face, as well as the tuning knob which can
be operated without backlash; within the broadcast bands, the frequency accuracy of the ICF-760l
is around 25 kHz.
At the left small face of the radio, You find a 6V DC center - negative jack to connect the
external power supply and a earphones jack, the
battery compartment is found at the back, the ICF-7600A needs to be powered from four UM-3 batteries.
Operating the ICF-7601 is an easy task: press the SW button to switch
the radio on and to select the shortwave range, then use the sliding switch to select
the desired shortwave band, position number 2 stands for the 49 m band, the
selected band in indicated by a tiny mechanically moved indicator just below
the frequency dial. On the
bandspread dial, the steps between frequency marks are 50 kHz, so You can "guess" a frequency
within 25 kHz. Look out for the interval signal or the accent of the speaker from cologn
somewhere between the 6.05 and the 6.10 marks for Radio Deutsche Welle on 6075 kHz.
The double conversion design is far better as far as rejection of unwanted
signals and mirrors is concerned, the dynamic range is improved but I would not
recommend connecting an external antenna to the little receiver - it works
best from the telescopic antenna.
Unfortunately, the ICF-7601 covers no out of band signals or amateur radio bands
nor is it equipped with a BFO for SSB or CW reception. So I do consider the ICF-76001
as a collector's item as well as a reasonable shortwave travel radio for the one's looking
around for a simple analog radio without too many pushbuttons. As on the used market,
You might find double conversion receivers with PLL synthesis for a little more money,
I would rather take one of these, e.g. a Sony ICF-7600D
with me on trips abroad, as I'm not afraid of these computer operated little genius.
