A week after I finished building my Black Paraset transceiver, I took
it out at night for a pedestrian mobile PM test run on 40
It is totally amazing to me that I could work coast to coast using the
Paraset with an 8 foot whip on 40 meters. I have done it with the KX1
before and it always amazes me.
I worked several stations on Feb. 14, 2005: WØAV, George, MO; W1PID,
Jim, NH; NFØR, Dave, MO; W3FF, Budd, CA; VE1GPL, Gerry, NS; KE6WAR,
Rich, Lake Isabella, CA; and KQ6XA , Bonnie, CA .
There were at least 5 other stations worked, I just forgot their calls.
Other stations who copied me were: KG4FSN, Juan, South FL; KE3OQ, Mike,
A few guys did not have any idea that I was operating PM using a Paraset.
They just heard me calling CQ and answered.
Were having a mild winter here in Colorado and PM operation at night
can be dangerous because of the bears in the area. Operation at night
is cool because the Paraset 'Tank' and 'Antenna' panel lamps blink on
and off with your keying making long eerie blinking shadows across your
The Paraset is a WWII Spy Radio. It is like a vacuum tube KX1. It uses
a 6V6 as a crystal oscillator / transmitter and has about 2 watts output.

There is a Paraset Yahoo group. Send an email to email@example.com
for a subscription. Wouldnt it be great if this were a club project
and someone was able to produce a hundred chassis?
The first picture shows the Paraset in operation right after I worked
Texas on 7038.5 KHz. The Paraset has a built-in key on the lower right
The backpack contains a BB590 NiCad battery and a Motorola Vibrator power
supply. The antenna is mounted on the backpack frame and I use a 30-foot
drag wire for a counterpoise.
This is how I operate the KX1 / pm except the Paraset is four times
bigger than the KX1 and the KX1 doesnt require a backpack power
The second picture shows a close up of the Black Paraset in its case.
I contacted 65 stations with my Paraset during the 2 / 7 / 05 Sprint contest
on 40 meters with a dipole antenna.
