Cross Country Wireless Release Mains Filter

Cross Country Wireless has released a filter designed to remove noise and interference on the incoming mains feed to radio equipment or high-quality audio equipment.

The filter first uses a differential filter on the live and neutral conductors to remove LF and HF noise from switch mode power supplies on the same circuit, ring main or phase. The filter then has a common mode filter to stop HF and VHF interference on all three conductors.

This also stops any RF signal or interference from the radio or audio equipment being fed back to the mains supply.

The combined filter system provides a reliable filtering system that can cope with almost any situation where severe electromagnetic interference is present on the incoming mains supply.

FCC Enforcement Action Update July 2017

A recent flurry of FCC Enforcement Bureau correspondence to alleged unlicensed broadcasters has targeted at least one more radio amateur — this time in the Greater New York City area.

Winston A. Tulloch, KC2ALN, of Paterson, New Jersey, has been visited again by the FCC, after several months on investigating Tulloch regarding a pirate FM station on 90.9 MHz.

Last November 2016, the Enforcement Bureau sent Tulloch a Notice of Unlicensed Operation after receiving information that he was operating a radio station. FCC agents used direction-finding techniques to zero in on a signal on 90.9 MHz coming from his residence."

DSLWP Satellite Amateur Radio System

Radio amateurs at the Harbin Institute of Technology (BY2HIT) are working on two micro satellites that are expected to be launched into a Lunar orbit in 2018

DSLWP is a lunar formation flying mission for low frequency (1-30 MHz) radio astronomy, amateur radio and education, consists of two microsatellites. As a part of the Change 4 mission, the satellites will be launched into a lunar elliptical orbit in 2018.

The amateur radio station on board DSLWP-A1 will provide telecommand uplink and telemetry / digital image downlink. An open telecommand is also designed to allow amateurs to send commands to take and download an image.

The satellites have a volume of about 50x50x40 cm3 and a mass of about 45 kg. Planning DSLWP-A1 downlinks on 435.425 MHz and 436.425 MHz and DSLWP-A2 downlinks on 435.400 MHz and 436.400 MHz.

A JT65B beacon is planned.
