*** Homebrew Radio things ***

Many hams build things with a large investment in time & parts that
are
worth far less... later. Here are some items from the estate stuff
I've
been selling that fit that description -- priced accordingly.

Unless noted, most of the items below are built on PCB material and
most
of the enclosures are made by soldering pieces of PCB material into a
box
-- not all sides may be present! Batteries not included! A few of
these devices come with schematics, mostly not. The wiring is all
open
enough that you can generally see what is going on.

Battery drainer -- LM317K (TO-3) plus a pot wired as a current sink to
drain batteries -- 4" x 3" x 1.5" -- $1

PL Tone generator -- Wein Bridge Oscillator powered by two 9 volt
batteries (not included). - $2

Touch Tone Encoder -- Western Electric Touch Tone Dial mounted in a
4"x4"x2" metal enclosure with power switch. Has a 4 pin DIN connector
plus matching cable terminated in a 1/8" mini plug. $3

Some kind of test oscillator with a NE556, two pots with anodized gold
(colored) knobs, pwr. sw.. LED,. & Banana jack outputs -- $3

HF Harmonic Filter built in a 5" x 2.25" x 2.25" LMB Aluminum box.
UHF
connectors. Probably good for 100W. $5

Digital Clock insides -- National MA-1001A demo board with MM5385N IC
plus 5 digit LED readout connected to another small PCB with a
3.579MHz clock circuit & MM5369N 60 Hz diveder. $5

60dB Sampling Tap -- HN female connectors for the main line and a BNC
for
the tap. 1KW in the line puts 1mW to the tap. -- $10

435 MHz power splitter with (3) N connectors. This is made out of
brass
sheet stock and is about 15" long by 1" square. $10

Varactor multiplier (unfinished) -- looks like it's designed for 144
to
432. Built in a 3.5" x 2" x 7/8" extruded aluminum case -- top plate
missing. Silver plated coils, Johnson 189-6-4 caps. It think it is
complete execpt for the input and output leads. $10

Some kind of VHF thing just started. Pomona 4"x2.5"x1.5" cast box
with a
couple 160-104 capacitors, BNC connectors, a miniature 50K bourns
pot., 6
capacitors mounted to gold plated terminals with a very pretty gold
flashed internal shield structure. Nothing is soldered -- this was
just
started. $10

Antenna Noise bridge? -- Pot & Cap plus 4 transistor circuit mounted
in a
5" x 4" x 2" enclosure. BNC connectors marked ANT & RX. Pwr SW. &
Led
Powered by a single 9 volt battery. - $10

Two Meter to 24-28 MHz receiving converter (I think!) -- 5" x 4" x
1.75"
-- $10


All of the above plus shipping, if necessary, naturally.
