Interference Cancelling System - The use of interference signal cancellation has been around for some time. The idea is to use an auxiliary antenna almost any random length of wire in addition to the main receiving antenna

Ak-Sar-Ben Amateur Radio Club - The Ak-Sar-Ben Amateur Radio Club, Inc. of Omaha, Nebraska is a general interest amateur radio club. With nearly 300 members there is someone involved in every aspect of amateur radio. We make a special effort to participate in providing communications support for public service events, Field Day, and teaching classes for those who wish to obtain an amateur(ham) radio license or upgrade their license privileges. The club sponsors regularly scheduled Volunteer Examiners as part of the ARRL VEC program. The club also hosts a flea market in the fall and hosts an all area picnic in the spring. There is evidence of the club as far back as the 1920s and has a long history of community service and promotion of ham radio in the city, county and state. The current club was started in 1945 the club has been affiliated with the ARRL since that time The club has hosted the Midwest Division Convention in 1985 and in 1994. Tthe club has participated in Kidz Explore in Omaha which is attended by over 77,000 people. The AARC is also involved with the radio merit badge program for the Boy Scouts with several members being registered merit badge councilors. The club operates two repeaters under their KØUSA callsign, 146.940 and 224.940. Both repeaters are open for all licensed amateurs to use. The 146.940 repeater is home to Midlands ARES and Douglas County ARES nets.

VLF-LF And the Loop Aerial - The article discusses the theory of loop aerials for receiving and how they reduce the level of local noise. A Loop Aerial is described suitable for use on the LF and VLF bands together with a circuit of an interface loop tuner and preamplifier. The discussion extends to the problems of amplifier noise and the advantages of tuning the loop.

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.

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.
