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. Price: $29.89

Here is a kit that is 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. Ideal VFO circuits for QRP rigs.
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
Price: $19.89
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 Price: $19.89
