The 160M No-Excuses Homebrew Vertical - 160m antenna designed for stations having a difficult time putting a decent signal on 160M from small or restricted lots.A 25 ft. vertical antenna, made from three 10 ft. PVC.

Pringles WiFi Antenna - DIY Wifi Antenna with a pringles can and extend your wifi signal, also known as cantenna.

Dummy Load Special Antenna - The wire antenna described in this page provides much stronger signal strength while staying within the concept of a dummy load antenna.

Agilent - Spectrum analyzers - Agilent maker of Oscilloscopes, Analyzers, Meters - Spectrum Analyzer (Signal Analyzer)

Amplitude Modulation - Amplitude Modulation (AM) is essentially a mixing process where the audio modulating signal is mixed with the radio frequency carrier

Handling of extremely strong signals K2 Mod - Makes reception at frequency of strong tx close by possible

RF Sampler - This circuit will let you look at the signal and frequency output of your transceiver.

LF Converter - Home made LF converter, listen to signals below 300 KHz

QLF Filter - Microprocessor based interface designed receives a signal from a Morse key, processes it, and re-transmits it to the radio. A microprocessor in the circuit is pre-programmed with a proprietary algorithm which makes a number of measurements and adjustments to the less percise human generated code.
