[Elecraft] Regarding Heathkit

[Joe K2UF]

I am currently building a new Heatkit kit.  I bought a complete 'cantenna'
kit at a recent flea market.  A lot more soldering then my K3 I built in
January but I think I will be able to handle the task.

My first kit was a Johnson Adventurer 50 watt crystal controlled xmtr.  My
'vfo' was a 243 case xtal with a screw mounted on the case to change the
freq a little.  If I remember the xmtr had less discrete parts then the K3
has boards ;o)

To build a paper-route and push-mower novice transmitter 'kit', you will
need a 1950's TV 
set and an old radio or two. Always check the curbs when you go out to
deliver your papers.

The power supply will use the transformer and the 5U4 rectifier from the TV.
The audio 
output tube will serve as a crystal oscillator and the horizontal oscillator
tube as the 
final amplifier (you can use two in parallel for more power if you have two
old TVs).

An old radio supplies the loading capacitor. If you find the right old radio
you might get 
one suitable for the final tuning capacitor, but since all the grownup hams
have ARC-5 
parts to burn, one of them will give you one for free if you ask nicely.

Coils can be wound on anything tubular with any kind of wire. Even several
popsicle sticks 
can be used to make a cool-looking honeycomb coil. Small parts will come
from the TV and 
radio, of course. Rule 9: there is no value of resistor or capacitor that
can't be created 
from series/parallel combinations of the contents of a 1950's TV set.

The transmitter can be built on a piece of wood, an old radio chassis or a
cake pan. You 
will have to buy the crystal ($2.95) with paper-route or lawn-mower money.
