A 24KHz input signal sampled at 25KHz will be converted to a 1KHz output signal. The output signal frequency is the difference in frequency between the input signal and the switch sampling rate. There’s neither rocket science nor smoke and mirrors here folks: it’s all done simply with op amps and resistors! _ Designed by Prject Wes Hayward, W7ZOI and Bob Larkin, K7PUA that appears in QST, June 2001īalanced Frequency Converter (Suitable for Frequencies up to 50kHz) - This circuit takes advantage of aliasing that occurs in any time sampled system.

_ Designed by Steven "Melt Solder" Weber KD1JVĪ Dirt-Cheap, High Current Power Supply - Here's yet another use for that pensioned-off AT computer that's gathering dust in the corner._ SiliconChipĪdvanced VHF Power Meter - The DVM (Digital Volt Meter) also displays the correct polarity sign. The only problem is it's a little heavy with the feed line and all, and putting it up in the raw New England woods can be daunting. Being able to switch bands between 20 and 40 quickly and without re-adjusting an antenna tuner is a nice feature. I made this for portable operations, mostly for "to the field" type QRP contests.
