90 MHz voltage controlled oscillator for FM
Band - Notice the abundance of 2N4401,
1 k resistors and 330 Ohm resistors? That's
because I have a lot of each. 2N4401's
weren't intended to be used as varactors,
but they work just fine. Don't be afraid to
experiment with the parts you have on hand.
Build this on a ground plane board. Layout
is important.

A Precision Portable Voltage Reference -
It has been said that a man with one watch
knows what time it is, but a man with two
watches is never sure. The same can be said
for a person who has more than one
voltmeter. In my situation, I have several
voltmeters in each of two different
locations a third of the way around the
world apart. The best solution would be to
send the meters to NIST traceable
calibration labs
A Push-Pull 300-watt Amplifier for 81.36 MHz
- This article describes a 300 watt

A Superhet/Direct Conversion AM receiver for
181.818 kHz - This is a description of
an experimental AM receiver for VLF. It is
crystal controlled to receive 181.818 kHz
(more or less) and operates as either a
single conversion superhetrodyne or a direct
conversion receiver. The bandwidths are
expected to be 15 Hz to 3.5 kHz in superhet
mode and 15 Hz to 10 kHz in the direct
conversion mode. Operation is from a singler..
