FOR SALE:
THE SIXTY CENT FIREBALL - SINGLE STAGE 80m CW
TRANSMITTER!
Here is a dual in-line package crystal oscillator
that will generate RF on the popular frequency
of 3.686 MHz in the 80m amateur band.
Add your 5 volt DC supply at about 20-50 mA,
a key and an anetnna and you will be on the air
with QRPp power and absolute minimum parts count!
Construction plans are available on line... see below.
Crystal stability means you will have no drift, chirp
or yoop with this tiny silver rig.
Even use it as a driver for a more powerful RF final.
Strictly speaking, you should add a PI network or
other matching circuit between the output pin
and antenna for correct antenna matching and
to attenuate the harmonics. Has approx. 10 to 20 mW
RF output. Add a few parts and you will have a fine
little QRP rig.
You will not be the first to have made real CW
contacts with a few milliwatts of power!
An experimenter's delight for the 80m ham band.
Available now for $1.00 each or TEN for just $6.00 plus
shipping!
