T2FD, The Forgotten Antenna - The terminated. tilted, folded dipole T2FD is a little known antenna that performs excellently. Compact in size compared to a half­-wave dipole the T2FD provides signal gain, wide frequency coverage, and exceptionally low noise characteristics.

Design a J-pole Antenna - Enter the operating frequency in MHz to calculate the dimensions for your J-pole.

KR1ST Magnetic Loop Antenna - This receive only loop covers a frequency range of about 5 MHz to 22 MHz and is built from readily available parts.

Loop-Magnetic by Dj9RB - Magnetic Loop - DJ9RB Frequency range 2 MHz - 10,2 MHz

Remotely-tuned loop antenna for LW and MW - This article describes how to build a loop antenna for low frequency (LF) and medium wave (MW) reception with remote-controlled tuning. The antenna is extremely sensitive and can be built mostly from parts from old radios and tape recorders. Like all loop antennas, it is highly directional, which allows you to null out unwanted noise sources.

The Low Frequency Receiving Loop - The Spreaders are 3 feet, making the loop 6 feet in diameter. There are 5 spreaders so the windings can alternate from side to side. There are 30 turns of 18 gauge stranded insulated wire.

Radio Scanner Citizen's Band DX Group - RadioScanner (Radio Sierra) russian citizens band radio club. Most operators are from CIS countries in Europe and Asia.

WD2XGJ Experimental Station - Experimental Longwave Transmissions from Tower Hill wayland Massachusetts Operator Name Warren, Ham Call K2ORS, Frequency: 137.7796 KHz

European 135.7 - 137.8 kHz Band Plan - This is not an officially recognized band plan for the European LF allocation between 135.7 and 137.800 kHz. This plan just contains my own observations and shall help the newcomer to get some orientation on where to find what.

European PSK Club Priority listing - The European Phase Shift Keying Club (EPC) was to promote an interest in Amateur Radio to sponsor a series of contests, awards and badges based on the administrative geography of European and other countries by using the PSK mode(s).
