You are listening to a news bulletin of the South African Radio League.


Radio Amateurs in Germany and USA were the first to pioneer communications above 400 GHz on the sub-millimetre wavelengths. The first-ever pioneering records established on these micrometre wavelengths over line-of-sight distances were done with less than 1 milliwatt. They were:

411 GHz (730 micrometres) DB6NT and DL1GIN, SSB - 50 meters

403 GHz (744 micrometres) WA1ZMS and W4WWQ, CW - 1,4 km

322 GHz (931 micrometres) WA1ZMS and W4WWQ, WBFM -1,4 km

The World Radiocommunication Conference 2019 (WRC-19) is considering new allocations in the 275 GHz to 450 GHz spectrum with its lower atmospheric attenuation for land-mobile and fixed services. The IARU feels that we have already staked our claim, as the earlier WRC-15 has already recognized the presence of the amateur radio service operation above 275 GHz.

The top end of the microwave spectrum overlaps into the Deep Infrared spectrum, but are separated by a narrow Terahertz gap covering 300 GHz to 3000 GHz (3 THz), i.e. a wavelength from 1 - 0,1 mm (100 micrometres). It manifests very unusual characteristics, such as X-ray qualities without any dangerous radiation, detect pipes in concrete, see through walls, and it will form part of the new allocations.


The results from the SARL Newby Party are in. Despite poor conditions, Woody, ZS3WL, managed to work 100 stations in the allotted 3 hours. We are really looking forward to the next one in November.

1st Woody Collet, ZS3WL with 444 points
2nd J.C. le Roux, ZS1CF with 42 points
3rd Pieter Jacobs, ZS6XT with 36 points
