Shelley's Sentinels of the Spectrum: Western Australian Group Explores Radio's Low Frequencies

SHELLEY, WESTERN AUSTRALIA – In the specialized realm of radio experimentation, where signals traverse vast distances on wavelengths measured in hundreds or even thousands of metres, a relatively new collective in Western Australia is making its mark. The Western Australian Low Frequency Experimenters Group (WALFEG), operating under the callsign VK6MJM, is dedicated to advancing the science, engineering, and technology of low and medium frequency (LF/MF) radio, bridging both amateur and scientific contexts.

Though modest in current size with approximately a dozen members, WALFEG's ambitions are significant. The group's foundational years saw a primary technical endeavour in establishing an operational station near Manjimup. This facility became active on the challenging 630-meter (475 kHz) and 2200-meter (136 kHz) bands – spectrum allocations that demand considerable technical ingenuity for effective use due to antenna size requirements and unique propagation characteristics. Subsequent efforts were directed towards implementing remote operation capabilities for this station, a strategic move to enhance accessibility and operational flexibility.

WALFEG extends a welcome to new members, indicating a desire to grow its community of specialised experimenters. The group's stated aim of promoting interest in LF/MF technology within both amateur radio and broader scientific circles suggests a commitment to pushing technical boundaries and contributing to a deeper understanding of this less-trodden segment of the radio spectrum. Details regarding specific meeting schedules are not prominent, implying a focus on project-based collaboration and on-air experimentation.

Guidance for this technically focused group is provided by President Professor Peter Hall (VK6HP), whose academic background perhaps underscores the scientific leanings of WALFEG, alongside Secretary Ms. Audrey Bell (VK6FAUD) and Treasurer Mr. Max Faulkner (VK6FN). Administrative correspondence is handled via a post office box in Shelley (PO Box 3010, WA 6148), and the group maintains an online presence via its QRZ.com page for VK6MJM. Professor Hall also serves as a primary phone contact (0400 801 531).

The Western Australian Low Frequency Experimenters Group, while still in its formative phase relative to more established clubs, represents a dedicated push into a demanding area of radio science. Its focus on establishing robust infrastructure for the long waves positions WALFEG to make valuable contributions to both the amateur radio community and the wider understanding of LF/MF phenomena.
