|This is an almost like new Collins KWM-2 that was
produced in 1960. The serial number is 9XX. The calibrator crystal is dated
January 1960. This transceiver belonged to a retired doctor friend of mine
who had stored it for decades. This KWM-2 has a solid main tuning knob,
as opposed to the later spinner knobs, and the VOX-TIME CONSTANT control
behind the meter inside the cabinet. This was standard on late 1960s KWM-2
production models. I do not believe it has ever had any modifications
done to it or ever been touched by a soldering gun. It looks like someone
purchased it in 1960 and maybe used it for a year or two and then put it
away. The first 5 pictures below are of this transceiver. The
last 3 pictures are of a KWM-2 that was produced in 1963, serial number 12XXX.
It belonged to the same doctor friend, and is also in the same condition.
The KWM-2, an 18 pound compact transceiver, makes it possible to move
one's operation from the desk top of the shack to the mobile mount in the
car, plane or boat. The KWM-2 went through rugged field and air operations
with combat units. Compactness and efficiency of the KWM-2 are achieved
through having all tuned circuits and serveral tubes function in the dual
role of transmitting and receiving. The same oscillators, mechanical filter
and RF amplifier serve both the transmitter and reciever. CW break-in and
monitoring sidetone circuits are built in.
The KWM-2 power input is 175 watts PEP on SSB or 160 watts on CW. It
transmits on voice or CW with a nominal ouput of 100 watts for complete coverage
on 80 through 10 meters. Standard equipment came with crystals for
all HF bands except 10 meters where one crystal was supplied with provision
for two additional crystals. The KWM-2 can be used without accessories
to drive the 30S-1 or 30L-1.
Other features include:
- Filter Type SSB Generation
- Inverse RF Feedback
- Permeability-Tuned Variable Oscillator
- One KC Division
