The Hallicrafters FPM-200 was one of the most advanced radios of its time:
very compact, mostly solid state, dual VFOs (accurate and stable), split VFO
operation, electronic tuning of intermediate circuits tracking with VFOs,
dual sided glass epoxy circuit boards, switching power supply, modular
construction. It was 20 years before the rest of the industry caught up
with the FPM-200 concepts.
The primary downsides of the FPM-200 were: the technology was not yet up to
the vision (germanium transistors, receiver IMD, low frequency of the
switching supply), and the street price was more than a complete S-Line at
the time (75S-1, 32S-1, 30L-1). The KWM-1, announced in the same year as
the FPM-200, paled in comparison in terms of vision and innovation.

I couldn't resist:
Grebe CR-18 (one of the 1st commercially-produced ham-only regen receivers -
ca. 1926)
National SW-3/Pilot Super Wasp - 1st mass-produced ham receivers (Pilot in
kit form);
National HRO - Revolutionized Superhet technology My Vote for THE Receiver
all of all time;
KWS-1/75A4 - SSB implementation;
KWM-1 - Transceiver concept;
FT-101/TS-520 - Large-scale import revolution with high value in packaging
features;
Ten Tec Triton series - SS finals;
KWM-480/TR-7 - Digital tuning;
TS-870S - IF DSP; and
Flex SDR-1K - SDR concept to amateur radio.
Nearly a ten-year interval in each category, beginning in the '20s. I
wanted to include Hallicrafters (my call-sign after all), but cannot think
of a really stand-out product, although the SX-28, SX-88, and DD receivers
deserve a place in history.

Kieth,
My vote is for the KWM2 because it brought the concept of transceivers
to amateur radio.
My second vote is for the Drake C line. I believe that was the
turnaround point of amateur thinking about receiver performance. Prior
to that time, the major consideration for receiver specs was
'sensitivity' - it did not matter how much noise was amplified, if it
was more sensitive, it was better.

The K3's performance clearly exceeds its price (check it out, two
possessives in once sentence and only 1 has an apostrophe) and I
believe it is a contender for greatest rig ever or at least very
noteworthy in the historical radio timeline.
How long do you think we have to wait before folks begin speaking of
the K3 as one of the most influential rigs?
And what rigs would you say are the most historically influential?
Which ones caused a major shift in the history of amateur radio?
KWM2A?
TS-520?
FT-101?
Drake C-Line (esp R4-C)?
FT-1000?
Century 22?
