***  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.
 
PL Tone generator -- Wein Bridge Oscillator powered by two 9 volt
batteries (not included). - $1
 
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.  $2
 
Some kind of test oscillator with a NE556, two pots with anodized gold
(colored) knobs, pwr. sw.. LED,. & Banana jack outputs -- $3
 
PPG Electronics project #880-CB, 13.5V 2 Amp, power supply kit, unbuilt. 
Most parts are under shrink wrap.  Power transformer & main filter cap
are missing. $4

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

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
 
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

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

Transistor Tester per July 76 Ham Radio, p.40.  Homebrew Aluminum case.
