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 broadcast bands.

ICF - 7601 International version, tropical bands 120 - 75 m
ICF - 7601L European version covering the longwave - band
Double conversion

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

Sensitivity

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 The main frontpanel layout has remained nearly the same, the mechanic frequency range pushbuttons have been replaced by electronic keys, but the set still comes with a coloured OFF pushbutton.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.
