Datakits 80-970 thru 80-1440
Serial PIC Programmer
(Photo shows only the board, but components are included)
This circuit uses the P16PRO software from Bojan Dobaj (you download from Internet and register for $25). This circuit will program all 8, 18, 28 and 40 pin serial programmable PIC's. The software will work under DOS or windows. Use the PIX12C5XX, PIC14000, the PIC16CXX series etc., see list. Make or buy an adaptor and you can program 64 pin PIC's. Here are the PIC's that this unit will program: PIC12C5XX PIC14000 PIC16C61, 62, 62A, 63. 64, 64A, R64, 65, 65A, 66, 662, 620, 621, 622, 642, 67, 71, 72, 710, 711, 715, 73, 73A, 74, 74A, 76, 77, 84, 923. PICF83, 84. PIC16CC924 PIC16C67X PICCR62, 83,84.

Variable Power Supply
The kit comes "complete", which means the transformer A.C. power cord and a fuse holder are included. Most power supply kits leave finding such things to the builder. Output via screw terminals, making this a good bench supply for the kit builder. Voltage may be varied from a volt up to about 24 volts DC and is well regulated; i.e. voltage is very stable. Using the LM317T I.C. and including the Philmore TR241 (24 volt, 1 amp) transformer permits an output range from about a volt to 21 volts. Higher current is available at the higher voltages but lower voltage are at lower currents; for example, around 5 volts output maximum is around 350 mA. Maximum current is available in the 18 to 22 volt range . Ripple (on line noise) is finite, making this a good kit for those audio and R.F. projects where you do not care to hear power line noise. Note: We do not recommend a beginner build this kit unless he has some experienced supervision to help. Any kit that connects to the A.C. power line is potentially dangerous to the inexperienced builder.

MONAURAL PREAMPLIFIER
Our audio amplifier kit works very well, but if your input is a tape head, magnetic phono cartridge or electric mike, the input level may be too low to do the job. This small preamp can be used in these applications; plus, we have included a mike that may be used with the circuit. Power at 6V to 12V (current at 12V is 3mA, only 2mA at 9V).
The gain is more than 40 dB.

17-1/2 Watt Mono Amplifier
A high quality audio amp that can operate on a low voltage, 12 V DC recommended. Uses the Hitachi HA13001 IC and a dozen external components for a compact and powerful monaural amplifier. Builder must supply his choice of speaker (4 or 8 ohm) and some heat sink grease to apply between the IC and the heat sink. Includes PC board and all parts. Build two for stereo.

R.F. Bug Sniffer
(Hidden Transmitter Locator)
If someone put a BUG (listening device) in your meeting room, would you know it? Todayfs small circuits make listening devices too easy to conceal to ignore. You may want to assemble this one for resale to nervous and needy users. A high quality circuit, should be considered even by the professional. It will detect any transmitter sending A.M. or F.M. or just C.W. at frequencies anywhere from ten to 450 MHz; peak sensitivity is in the 80 to 120 MHz portion where many bugs would be found. The signal strength is indicated on a bargraph, so the closer to the source you get, the higher the indication. With some practice, you should be able to find a covert transmitter to within a few inches of its location. "Professional" bugs, placed by serious operators can be found easily. Operation on 9 Volt battery for portability.

PLL VFO EXPERIMENTER'S PACKAGE
(Photo shows only bottom board and the top board, with digital readout and keypad, photo to be added soon.)
PLL-VFO Experimenter Package (experienced builder only) 440Khz to 185mHz.! This new VFO Circuit is a two part (two board) system for the experimenter. The "Bottom Board" (photo) is the PLL and VFO, complete with an area for the experimenter to add whatever circuit he desires; such as a transmitter, receiver, transceiver etc.. The "Top Board" (photo not here yet) is a controller with a keypad for frequency entry and an LCD digital readout that displays frequency. The Top Board controller communicates with the MC145170 chip on boards may be stacked with spacers and will mount neatly in a Philmore No. PB107 plastic case (not included). Not intended to be a complete kit, this circuit pair is intended to provide a highly flexible platform for the experimenter, student or Ham radio builder etc.. The circuits provide Rock-Solid frequency control with a very easy to use human interface (that's fancy for push-bottom keypad and readout). Included are circuit ideas, in schematic form, including a forty-meter transmitter and a radio receiver circuit. The prototyping area is large; the user can build a simple or multi-stage AM or FM receiver, CW rig, signal generator etc. The circuit may be used with various oscillator designs from 440Khz to 185Mhz. The circuit employs an MC145170 PLL IC which provides drift-free tuning with considerable stability. Operates on 12 volts DC. You will need up to 100mA to power the kit plus don't forget to add enough current capability to handle your own addition to the PC board.

VFO KITS, for Ham Radio
Two Kits Here are two kits that are a lot of fun to build and can be used in a number of Amateur Radio projects. Not sure what to do with a VFO? Well, included with the VFO kits are schematics for a transmitter and receiver. Or use the VFO for your own projects. The circuit is a Clapp Oscillator and our designer is proud of his "triple-pot" circuit design. Two of the pots are trimmers, used to select the segment of the band that you want to tune. Select just the CW portion of the band, SSB portion or the entire band. The narrower slice of the band that you select, the finer the main tuning will be. Which can eliminate a costly ten turn pot, vernier dials etc. These are ideal VFO circuits for QRP rigs.
40-METERS VFO Kit
Tunes to from below 7.00 MHz. and up to about 7.300 MHz.. Included is information for making the circuit into a 30 meter VFO with some additional parts that you supply. Provision has been made for RIT/XIT offset. Buffered output; board size 1.6" x 3.0", 12V DC operation.
40-Meter VFO Kit No. 80-1404
YDI Price $24.90
80-METERS VFO Kit
Tunes from below 3.5mHz up to about 4.0 MHz.. Provision has been made for RIT/XIT offset. Buffered output; board size 1.6" x 3.0" , 12V DC operation.

Amateur Radio
Receiver Kits (CW, SSB)
(Ham Radio bands)
Compact and easy to build and will receive an entire ham allocation in the band, CW and SSB. Great for monitoring W1AW code practice, ease-dropping on Nets etc. Operates on a 9 Volt battery, and has audio output enough to drive a speaker; or, use with headset. These circuits employ a unique three-pot* Varactor tuning system. You can set the ends of the band that you wish to receive; or, receive all of the band. The advantage to receiving just a portion (say just CW or just SSB) is that the tuning becomes much more precise and can eliminate adding an expensive ten turn potentiometer in order to achieve fine tuning. The PC board size is 3" by 3", which will fit nicely in a number of cases along with a battery. You will need to find your own (2)knobs, antenna connector (BNC, UHF, Fahnstock etc.) speaker (8ohm) and case.
