ICASA EXTENDS THE SARL 5 MHZ LICENSE
ICASA has extended the SARL 5 MHz license till the end of February 2014. This follows SARL application for ICASA to review the license and grant facilities up to at least the start of the WRC 2015. Currently the SARL holds a pilot license for 5 250 and 5 260 kHz. While the SARL applied for extension of the license for a further period it also appealed to the Chairperson of ICASA, Dr Stephen Mnube, to consider issuing the SARL with a long term authority to use these two frequencies to continue propagation research till at least the WRX15 conference.
The SARL is currently analysing the results of the special weekend 5 MHz activity event held in early November. The winner of the book prize is Barry Newton ZS2NF of Uniondale.

STUDIES OF IONOGRAMS SHOW SUPREMACY OF THE 5 MHZ BAND
The ionograms generated by the South African ionosonde network clearly illustrate the supremacy of the 5 MHz band for short range, near vertical incidence skywave (NVIS) communications under certain conditions. These typically happens during the morning and late afternoon when the 7 MHz band does not support short range, sky wave communications and the 3.5 and 1.8 MHz bands suffer from high noise levels.
During the middle of the day the 7 MHz (and 10 MHz during high solar activity) band is typically the most effective medium for short range, sky wave communications.
Permanent access to the 5 MHz band will ensure that the amateur radio community can efficiently contribute to emergencies requiring short distance communications beyond line-of-sight as typically required in hilly and mountainous terrain.
The South African ionosonde network is unique in Africa and place South African radio amateurs in the very fortunate position to monitor reigning, short range propagation conditions and to improve their skills and experience accordingly.

SARL Members will have access to 5 250 and 5 260 kHz as well as 472 kHz on registration requiring the completion of a registration form which can be downloaded here.
Once completed please email it to firstname.lastname@example.org. Processing time is a max three days.
All registered users will be listed here
The SARL has been granted by the Independent Communications Agency of South Africa (ICASA) access to two frequencies in the 5MHz band as well as 472 kHz . These pilot licenses are valid till 31 December 2013. It should be noted that use of these frequencies is limited only to Members of the South African Radio League
Maximum Bandwidth 3 kHz Maximum power 100 Watt
Preferred mode USB/CW
SARL members may however also communicate with amateurs in other countries outside South Africa with amateurs licensed to use 5MHz
5250 MHz has been set aside for various propagation research projects. Visit the this page for regular updates.
5260 MHz USB for general QSO's by SARL Members
Activity Reports and SWL Reports
SARL members making contact on 5260 kHz must keep
logs and are requested to submit a copy of their logs to
