NEW Kits Announced in May 2003
PICmi
cro® Programmer/Experimenter
A Learning kit. This may be the best self-teaching/learning kit for a PIC (programmable IC) that we have in the line; and yet it is not expensive. Kit assembly is easy and any moderately experienced kit builder can put it together in an hour or so. Once built, a terrific educational system is at your finger tips. The kit connects to the the serial port of a PC (you supply a 9 pin straight through cable). You immediately program the PIC using the user interface software provided and the software runs, flashing LED’s on the board in a definite sequence. Now you learn how to change the program to change the sequence. A 45 page manual and software is easy to download (free) from an internet page. It will take you through the process of learning programming of PICs. And how to use inputs and outputs to switch the LED’s. The circuit uses the new Microchip® 16F628 and learning about it will teach you how to use any PIC in that series; and the basics for programming PICs in general.
No. 80-812 PICmicro Programmer/Experimenter Kit
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

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. 80-Meter VFO Kit................ No. 80-1408

NEW in 2003
Amateur Radio
Receiver Kits (CW, SSB) 
(Ham Radio bands)
CLICK PHOTO FOR LARGER VIEW
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.
20-Meter Receiver Kit ..................... No. 80-1420
30-Meter Receiver Kit...................... No. 80-1430
40-Meter Receiver Kit...................... No. 80-1440
* Photo is of a prototype and the finished kits have three
pots and look a bit different.
A new photo will soon be taken to replace the one above.
