The FCC, and the US Department of Defense are cooperating in an effort to eliminate the possibility of amateur radio interference on 70 centimetres to critical systems at White Sands Missile Range (WSMR) in New Mexico. The Defense Department’s Regional Spectrum Coordinator contacted the FCC in March, seeking information on whom to contact regarding detected amateur transmissions it believed could pose a threat to a critical WSMR system operating on 70 centimetres. The FCC, in turn, asked ARRL to be involved in the discussion and any necessary remedial efforts. It is to be noted that the Amateur Radio Service is a secondary service on the band…………READ MORE .
DARC reports 35 Electrical Noise Area Monitoring Systems (ENAMS) have been delivered and another 20 locations are sought as part of the effort to monitor the interference from human-made noise on the HF bands
ENAMS is based on nationwide installed measuring stations that work as a network. With their help, the DARC can make scientifically reliable statements about interference levels on the frequencies. As is well known, the interference has increased in recent years, as various consumer devices drive up the noise level.
The ENAMS project was funded by the DARC Membership Pro in 2018.

There have been some remarkable contacts made on 144 MHz recently via Trans-Equatorial Propagation (TEP) from the Caribbean to South America with many in the region of 4000 to 5000 kms. One of the most impressive was a contact between P41E on the island of Aruba and LU2EPO near Buenos Aires in Argentina, a distance of just over 5400 kms……………….CLICK for more.
