The Japanese company Panasonic, a part of Matsushita Electronics, had always
been concentrating on the consumer electronics segment and entered into
"multiband receiver" business with it's T-100 in 1965.
With their sets, Panasonic aimed at the same costumers segments as Sony did,
but their sets always offerend an outstanding price / performance ratio. Most
of their sets were popularly priced, Panasonic always had some perfectly
processed top range sets with a corresponding sum on the price tag...
The RF-2200 (European designations was DR-22)
was an early conpact size portable shortwave receiver with a linear analog dial
which even offered SSB reception. In 1978 Panasonic presented the
RF-2800 / DR-28, a portable set with a similar shape which was equipped
with a digital frequency counter and came for a reasonable price. The
RF-2900 / DR-29 with the added preselector had a superior unwanted / mirror signal
rejection.
The large RF-4800 / DR-48 and its successor
RF-4900 / DR-49 with their conventional
receiver design and frequency counter was a bit outdated when it appeared on the
market, it stability and selectivity did not perfectly match what one could expect
for the money.
In 1980 a slightly downgraded version of the RF-2800 under the designation
RF-2600 sold for 290 US$ remained the best priced "real" shortwave receiver
with a digital frequency display for quite a while. Two years later, the
RF-3100 was the first PLL synthesized shortwave
receiver from Panasonic, it offered superior frequency stability and good
selectivity due to it's two IF filters. The RF-6300 with PLL synthesizer circuitry
ad again the enormous impressive size of earlier sets, the high end microprocessor
controlled RF-9000 even surpassed it by it's size, weight and of course the price.
The smaller microprocessor controlled RF-799 with it's 10 station memories and
a similar size like the legendary Sony ICF-2001 was the first in a series of
small leightweight receivers. Panasonic concentrated on this segment of
travel shortwave radios for a few years and finally left even this segment
in the middle of the nineties.
