Antenna Noise and Signal Cancelling at LF - The fact that the phasing between a wanted signal and an unwanted signal can be different on different antennas is put to advantage. With this condition, the unwanted signal can be cancelled out by controlling amplitude and phase. The heart of the system is some form of phase control circuitry.

A 80/40m DDS controlled QRP CW transmitter - JUMA-TX1 is a 5W CW transmitter for the 80/40m bands. Juha (OH2NLT) and Matti (OH7SV) have had high quality CW keying and a compact size as design goals for this project. No coils need to be wound to construct this transmitter!

Antenna Noise and Signal Cancelling at LF - By using the signals from two antennas, controlling their relative amplitudes and controlling the phase of one of them, unwanted signal or unwanted noise can be phased out. Circuitry is described which uses the signal from a wire antenna to provide selective cancelling against the signal output from an LF loop antenna.
