DCI Digital Communications - Band pass filters, for radio frequency interference problems.

About digital modes - The digital modes provide a wonderful opportunity for those of us who would like to work on the HF bands but find CW too difficult and SSB phone prohibitive because of interference problems. The digital modes are easy to set up and get operating, require low power and a narrow band.

Albuquerque Transmitter Hunting - An active group of Amateur Radio operators who locate hidden transmitters for fun and in times of need, such as determining the source of interference to local repeater systems or individuals who use the Amateur Radio bands illegally.

Electriduct - Cable protection products - Offers cable protectors, cord covers, cable guards, management products, solutions and supplies. Protect your cable, wires, and hoses from foot, small carts, and vehicular traffic with the trusted Linebacker Series of Cord Covers.

New Developments with PLC in Japan - The Japan Amateur Radio League (JARL) is cautiously watching new developments concerning the commercialization of Power Line Communications (PLC), while continuing to carry out joint experiments with a high speed power line communication promoters' alliance to reduce potential interference to radio communications.

Are you ready for BPL - Broadband over power lines (BPL) is a technique for transmission of high speed data (broadband Internet) over powerlines. Access BPL technology injects radio frequency energy into powerlines which were not designed for transmission of radio frequency energy, and leak substantial energy that causes interference to radiocommunications service

BPL Interference - Zip file taht contains a tutorial section that explains several different BPL technologies
