In the same years - or a little bit later - then Sony's ICF-7600A and the Toshiba RP-F11L, Panasonic presented the analog double conversion set RF-B50 in the year 1984. In a similar arrangement as found with the other sets mentionned above, You can tune in the common shortwave broadcast bands on a bandspread dial with an accuracy of around 25 kHz, a small red LED acts as tuning indicator. The selection of two different I.F. bandwidths makes a significant difference to the competing sets.
The Panasonic RF-B50L is portable shortwave travel radio, the double conversion
set comes in a quite compact cabinet with the dimensions of a pocket book,
185 x 112 x 35 mm / 530 g.
The silver coloured plastic cabinet with the red decorative stripes on both sides
of the dial give an elegant appearence to the set.
At the right small face of the receiver, You find the tuning knob, in contrast to cheap
shortwave radios from the discounter, tuning is accurate and without backlash.
Panasonic's RF-B50 is easy to operate, like the Sony analog shortwave radios. Set the main switch to ON, press the SW button, the BAND SELECTOR in position 1 will select the 49 m shortwave broadcast band. Look out for the news coming from Cologne somewhere between the 6.05 and 6.10 frequency marks, and You are tuned to 6075 kHz. In case of an interference from an adjacent channel station's carrier, switch to the narrow filter, that's it...
The sensivitity of the RF-B50 is good, selectivity is above average when
switched to the narrow I.F. filter. Thanks to the double conversion design,
unwanted signals from mirroring 900 kHz below the tuned frequency are not found.
