*** RF Attenuators ***
 
Heavily built RF Attenuator, adjustable between 0-50dB in 10dB steps. 
8" flying leads w/one terminated in a BNC Bulkhead female and the other
with an N Male connector.   Looks like it should be good to at least 1
GHz. 3 1/2"
diameter by 4" deep overall and weighs about 4 pounds.  Tapped holes in
the front frame for panel mounting.  No manufacturer indicated. A 3/8"
shaft adjusts by pulling (with a spring return) and turning so there is
no chance of inadvertent resetting.  No knob nor dial is included.  $25
 
Adjustable RF Attenuator 0-10 dB -- Telonic TB-50A.  0-10dB (1dB steps)
50
ohm RF attenuator-- 3" diameter by 3" deep w/ side mounted BNC
connectors.  $15
 
6 dB low power pads with N connectors, male on one end, female on the
other. Approx. 1"x1"x3" overall.  2 left.   $10 ea.   
 
 
***  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). - $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 divider.  $5

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. $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

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. 
NPN/PNP select switch is broken but, a replacement is included along with
a copy of the article.  Nice sealed Weston 50uA meter.-- $15
 

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