Net Manager: TJ Sheffield, KL7TS
The South-Central Simplex Net (SCSN) is held every Wednesday at 19:00L (7:00 PM), local Alaska time. The purpose of the Net is to test equipment, encourage station and operator capability upgrades, and to utilize the frequencies available to the Amateur Radio Service.
Anchorage Amateur Radio Club (AARC) involvement with the SCSN began in June 2020 when long-time host and Net founder John Lynn, KL7CY, with assistance from Craig Bledsoe, KL7H, suggested the AARC take over operations.
The original Net date and time, on Tuesday at 20:00L, was changed to Wednesdays at 19:00L to reduce schedule conflicts among operators.
The Net originates from the Radio Science and Operations Center (RSOC) with a core group of operators:
- Richard Tweet, KL2AZ
- TJ Sheffield, KL7TS
- Keith Clark, KL7MM
- Kevin Opalka, KL1V
In addition, distributed Net Control Station (NCS) operators are utilized and much appreciated. A spreadsheet reflecting Net participation on a month-by-month basis is available.
The SCSN opens at 19:00L on 146.52 MHz, but changes frequencies and modes as the Net progresses. The Net returns to 146.52 MHz after each band/mode excursion. Listen for instructions from NCS regarding upcoming frequency and mode changes. Packet Radio, APRS and MESH network check-ins are accepted at any time during the Net, with early check-ins beginning at 18:00L (6:00 PM).
The Net operates in the following sequence (as of January 3, 2024).
