In 1957, the American company R.L.Drake introduced an amateur radio receiver
with a completely new design philosophy - the R 1-A. This small set was a challenge and
did - in comparison with the heavy black or dark grey boatanchor competitors
perform surprisingly well. In 1960 - 1966, Drake brought several receivers
in the R - 2 Series, covering amateur bands only.
In 1964, Drake presented the first receiver of their very successful R - 4 series,
this double conversion set offered a dial accuracy of less then 1 kHz in the
Amateur bands and additional broadcast band segments, separate plug in crystals
for each band allowed the extension of the receiver's coverage. The
R - 4 B and the R - 4 C,
which offered all the possibilities of signal processing still found on modern
receivers, like a choice of IF filters, passband tuning, notch filter and a
switchable noise blanker, could be connected to an optional external frequency
synthesizer: The FS - 4 allows continuous coverage up to 30 MHz without gaps.
The receiver R - 7 / 7A was still based on a similar circuitry.
It covers the complete AM spectrum from 10 kHz - 30 MHz using 60 band segments of 500 kHz
each and displays the reception frequency by means of an internal frequency counter.
The R - 7 reached everything, that was possible in the field of
amateur / semiprofessional receivers in 1981 and was considered as reference receiver
for many years. Shortly after, Drake withdraw from the shortwave / amateur radio market
and went into satellite receiver business.
In April 1991, Drake made it's comeback in the shortwave receiver market with their
famous R - 8, a set that got an enthousiastic welcome as well
as quite some criticism, changing the IF bandwidths and reception modes on the original
model was a pain, the pushbuttons changed modes / bandwidths only in one direction,
to switch back to a wider IF filter, You had cycle through the whole range of filters
again. The R - 8 A allowed direct access to all IF bandwidths and modes and became
one of Drake's finest sets.
In the range of shortwave receivers, Drake offered a whole range of simple portable
shortwave tabletop sets, from the AM-only SW-1 to the SW-8.
You will find the older hollow state sets of the R - 4 series in the
Drake Boatanchors section.
