Active HF antenna - An active HF receiving antenna circuit by G7BCJ

Why terminate a Beverages - Terminating the far end of the Beverage makes it unidirectional. It also makes the receiving angle of the antenna lower.

Comparison of Beverage antenna - A ranking of receiving antennas based on noise being evenly distributed in all directions. These rankings are most accurate in the frequency range of AM broadcast, 160 or 80 meter bands

Receiving antenna for low bands  ^pop - K9AY loop antenna installed at PA6Z Contest group. This is a receiving antennas for the low bands (160m, 80m and 40m). Include schematics and info on a building the control box, preamplifier and low-pass filter

The K6STI Receiving Loop  ^updated - This relatively unknown antenna does an amazing job pulling weak low band signals out of man-made noise backgrounds

HF Receiving Loop Antenna - HF receiving loop antenna, an easy-to-make receiving loop antenna for HF

Small magnetic receiving loops - Article about magnetic loops, construction notes and diagrams

Active receiving antennas - An active antenna is sometimes used for receiving purposes in instances where a normal antenna would be impossible to accommodate in a physical sense.

6m Half wave vertical - This antenna is very useful for receiving or scanning purposes, but you can use it for transmitting, too. It is 2,94m long and has a pi-configuration (Collins-Filter) for the matching.

National RF, Inc. - National rf provides consulting engineer services, and manufactures direction finding antennas, test equipment, communications receiving equipment and adjuncts, satellite antennas, voice amplification and audio equipment.

G4ILO Receiving weather satellites - If you are interested in the environment, the weather and other natural phenomena then there is something magical about being able to see pictures of the earth from space just as it is right this minute. One way you can do this is by receiving images from weather satellites.

Electron Tubes and Vacuum Tubes for Industry - Electron tube and vacuum tube stock-list with prices 4. Audio, broadcast and industrial tubes, triodes, tetrodes, thyratrons, ignitrons, vidicons and CRT's, microwave devices, nixies and receiving types + Bird RF devices and test equipment. Quality tubes at reasonable prices with many hard to find items available

Radio Australia ABC - Online in RealAudio and Windows Media formats, with multiple language shortwave schedules, and instructions for receiving Australian satellite radio and TV (AusTV).

DTMF decoder - A very easy to use program to decode DTMF dial tones found on telephone lines with touch tone phones. The DTMF Decoder is also used for receiving data transmissions over the air in amateur radio frequency bands.

MMvari - MMVARI is a multi-Mode SoundCard Ham (Amateur) Radio program for receiving and transmitting the RTTY-PSK-FSK-MFSK modes. The program was written to experiment with the efficiency of transmitting Japanese and East Asian languages (HL/BV/BY) using the VARICODE

GorbTrack - GorbTrack or Geostationary Orbit Tracker is a freeware program intended to be an aid in finding geostationary satellites. It produces output helpful in aiming dishes for receiving television broadcast satellites. The program also displays several astronomical values like the positions of the sun and moon

ATPDEC - Atpdec is an open source program that decodes images transmitted by POES NOAA weather satellite series. These satellites transmit continuously, among other things, medium resolution images of the earth on 137Mhz. These transmissions could be easily received with an inexpensive antenna and dedicated receiver. For more information about receiving POES satellite images consult the rig site.

Common-Mode Noise - Receiving Common Mode Noise shows how lack of a balun can contribute to system noise

A 6M Transverter - Build a transverter based on a 6M receive converter. A 32MHz TTL oscillator is used as the local oscillator for both transmitting and receiving. RX/TX switching is handled by three SPDT relays.
