In 1991, Panasonic presented the RF-B 45, a travel shortwave radio with SSB capabilities. The "little brother" of the RF-B 65 is very similar to Sony's legendary ICF-7600 D, anybody knowing that receiver, can easily operate the RF-B 45 without problems.
Nearly in the same time, when Sony presented the ICF-SW7600, Panasonic introduced the RF-B45, a double conversion travel radio with SSB capabilities. The small set powered from four UM-3 / AA cells is based on PLL synthesizer technology and comes with a frequency entry keypad, 18 memories and a clock with timer functions.
With a size of 204 x 119 x 37 mm and it's weight of 620 g, the small travel radio has the dimensions of an average pocket book. Is has a fold out stand and the back like the similarly sized Sony sets. The telescopic antenna has a flexible joint and can be moved in vertical position.
The left part of the front panel is taken by the speaker with a diameter of 7 cm.
The pushbutton OPERATION with a green backlit LED will switch the radio on or off, use the key SLEEP to let the set play for another 90 - 60 - 30 Min. until automated shut off.
Similarly as found in the ICF-7600D, some controls are located at the set's right small face of the cabinet: the volume control and just below a small switch for tone (LOW/HIGH). The MODE switch in position NOR/FIX will activate 5 kHz tuning steps, in NOR/VARIABLE thze small round fine tuning control is active and You can vary the frequency slightly to tune in signals in between the 5 kHz channel spacing (frequency not indicated in the display), SSB/VARIABLE will activate the BFO for the reception of SSB and CW signals, use the fine tuning control again to select the tone pitch. I think, this arrangement does remember me slightly to a set in our kitchen made by Sony...
At the left small face of the cabinet, You find the jacks for a center - negative external 6 V DC power supply, earphones, a tiny attenuator switch DX/LOCAL and an antenna socket (nor for sets sold in Germany, a simple randow wirde antenna comes with the RF-B45.
As most of the buttons are self explanatory, operating the RF-B45 is not a real skill: When You turn on the radio, the button OPERATION is backlit green - yellow. Press the keys for AM, FREQ - 6 0 7 5 - ENTER, and You should arrive at receiving the signal of Radio Deutsche Welle from Cologne, at least as long as You life in central Europe. If this is not the case, make sure, the telescopic antenna is pulled out completely, the attenuator switch at the left face should be on DX and MODE at the right face of the radio in position NOR/FIX.
Shortwave performance is what You would expect from a decent shortwave portable:
In comparison with Sony's travel radios from the '7600 series, sensitivity and
readibility of a signal seems to me slightly better with the Sony's. The sound
of my old Sony ICF-7600D has more volume and bass,
the RF-B45 gibes a more technical sounding reproduction, the faint signal coming
from WWCR just above the 19m band is coming in slightly better with the Sony.
With the more powerful signals of the European shortwave broadcasters, the
quality is identical for the Sony and the Panasonic.
