  Special Joint Club - Optical Communications Presentation

  Optical Communication and Recent Developments

  The Radio and Electronics Association of Southern Tasmania Inc. is joining forces with the Brisbane VHF Group for a special joint presentation night.

  Rex, VK7MO, has been asked by the Brisbane VHF Group to give a talk on the VK7 Optical Work that was done now 14 or more years ago and resulted in the one way Crossing of Bass Strait.  This will be a joint meeting from the REAST main club room with the Brisbane group participating by streaming.

  Given the elapsed time Rex decided to also cover recent developments which include:

  • Improved LEDs and Lenses
  • Changing from 630 nm to 730 nm to avoid concerns about bright lights that were reported as bushfires
  • The use of K1JTs FST4 mode that uses less than 1 Hz bandwidth and can work to -45 dB on the WSJT scale
  • Exploring Over-the-Horizon propagation with Richard VK7ZBX, including cloud and aerosol scatter

  It happens Wednesday the 28th August 2024 from 7:30pm AEST and is streamed into the clubrooms of the Brisbane VHF Group.

  To take a look at some of the extensive archives that REAST has on it's website - take a look here.

  See you there or on the stream.
