Operation
Sony's ICF-SW22 is very similar to the ICF-SW15, but everything is one step smaller: with its 115 x 73 x 28 mm it has the dimensions of a cigarette packet and weighs just 200g; the front panel is similar to that of the ICF-SW15.
Two UM-3 / AA batteries are needed to operate the unit.
The left half of the front is taken up by the speaker. Most of the right half of the front panel is taken up by the vertical band spread dials for the 49, 41, 31, 25, 19, 16 and 13 m shortwave bands. In the slit-shaped dial on the far right, you can see the pointer for medium and the FM broadcast band.
At the bottom right are the band selector keys for SW, MW and FM. Pressing the band key turns the receiver on, a small red dot marks the active range. The desired shortwave band is selected with the slide switch on the top of the unit; a dot-shaped yellow mark in the window above the frequency dials, which is only visible at second glance, indicates the active shortwave band. Pressing the turquoise OFF button turns the ICF-SW22 off, the LOCK slide switch with its red marking blocks the band buttons and prevents the ICF-SW22 from being switched on unintentionally in your luggage… A small red TUNE LED serves as a rudimentary field strength indicator.
The volume control and the tone control switch are located on the left face of the unit. The tuning knob on the right face acts backlash-free, there are frequency marks every 100 kHz.
The operation is completely uncomplicated: the set designed to please a customer segment looking for a set that is easy to operate. It is switched on with the range key, for example with SW, the slide switch in position 1 activates the 49 m band, search for a station and set the volume to the optimum level. With the analogue receiver, a station must be identified by the programme, the station identification before the news, or by the interval signal.
The set is not capable of receiving single side band signals of radio amateurs or radio teletype signals, several off-band frequencies cannot be tuned. The ICF-SW22 competes with the ICF-SW1, which has very similar dimensions but as a PLL synthesized receiver and its appearance of a pocket calculator, it might not be the receiver of choice for the ones who want an easy to operate radio…
The ICF-SW22 stands out from many other similar sets with analogue dials - unlike many Chinese sets from the discounter, the Sony is a real shortwave radio.
