*** 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.
