Note!
The
president of Katsumi Electric Co passed away in March, 2011,
and
it appears that the family has no interest in keeping the comapny
going. Apparently they have been unable to find someone to
take
it over, so we are no longer able to get Katsumi products.
These were excellent
products that were a part of the communciations scene in Japan and it
is a shame to see them go.

Katsumi Electric Co. has been making commercial keyers since
the
1960's, their equipment has an unsurpassed reputation for
rugged reliability. Katsumi equipment is used in virtually all testing
environments in Japan including amateur, commercial, and military.
Morse Express is Katsumi's agent in North America, and
all of the products shown on this page are stocked and usually
available for immediate delivery. Other products are
available by special order.
EK-130
Electronic Keyer

The EK130 Deluxe Electronic Keyer is a commercial grade electronic
keyer, and this is the keyer
used in Japanese Morse examinations. All of the controls are
mounted on the front panel, along with a "speed meter" which
displays the operating speed in words per minute, characters
per
minute (both PARIS and CODEX), and Japanese commercial radio class test
speeds.
Terminals are provided for connecting a paddle and/or bug and/or
straight
key. The keyer itself will function in "bug"
(semi-automatic) mode at the flip of the front panel switch.
Specifications:

Speed range: 6-60wp,
Keying circuit: reed relay
Power Source: 110-120VAC or DC9-16V External
Size/Weight: 185(w) x 50(h) x 108(d)mm / 890g
KM-23
Dual Paddle

The Katsumi paddle is heavy duty all the way, from its attractive
"retro" style to its heavy cast-iron base. It is not a precision
instrument, but has a surprisingly light feel at a very
reasonable low price. In fact it would seem to be
the only standard paddle on the market at less than $100, and better
quality than many more expensive paddles. The
pivots feature steel ball and cup bearings, and the contacts are
machined hard silver.
The KM23 paddle weighs 2 Lb 10 Oz. Base diameter is
4" diameter, paddle maximum height is 2" and
the lever length is 4"
EKM-2B
Code Practice Oscillator

Katsumi's EKM2B Code Practice Oscillator is without a doubt the nicest
sounding and most flexible unit on the market. Whether you
are learning to send, or teaching a class, or practicing over a
repeater, the EKM2B will do everything you need.
The circuit is a transistor oscillator, producing a pleasant
near-sine-wave tone that you can listen to comfortably for hours.
The oscillator is transistor keyed for chirp-free operation at high
speed.
Features include an on/off switch with green LED, separate sliders for
pitch (600-1800Hz) and volume, headphone jack, and "record"
jack to provide line-level (4mV 600 Ohm) audio for tape recorders and
other devices.

EK-160
Electronic Keyer / Paddle
Click to view in
full size
The EK160 Electronic Keyer / Paddle is a commercial grade
electronic
keyer with a precision dual paddle built in.
Terminals are provided for connecting a paddle and/or bug or straight
key (to use the
keyer as an oscillator and to buffer the keying of a transmitter via
the relay). The keyer itself will function in "bug"
(semi-automatic) mode at the flip of the front panel switch.
Speed setting is done via a front-panel control which is calibrated in
characters per minute (5cpm = 1wpm, approximately ).
The adjustable paddles are switch-reversable for left-handed operators,
and the contact spacing is easily adjusted on the front
panel.
Iambic keying features full dot and dash
memories. The weighting ("code ratio" can be adjusted from 1:3 to about
1:4.
There's a built in monitor with volume control on the front
panel
and pitch control on the back,
and a jack for headphones or external speaker (8 Ohms, 300mW).
Built-in high-speed reed relay supports negative-keyed rigs
with
up to 280VDC and 2A on the key line, or use JFET keying for
transistor-keyed +V rigs and save wear and tear on the relay..
Specifications:
Speed range: 6-50wp,
Keying circuit: reed relay or JFET
Power Source: 110VAC o r 220VAC
Size/Weight: 9x4x2.5in, 2 Lbs, 12 Oz.
