& FREQUENCIES >
Table
of weather satellites that transmit in the 137 MHz band, commonly
received by hobbyists using SDR receivers and SatDump software.
These satellites primarily transmit APT (Automatic Picture
Transmission) or LRPT (Low Rate Picture Transmission) data, which
SatDump can decode.

VK6YSF JS8Call and
Olivia 8/250 operations.
Current activity is generally
focused - though not restricted to - JS8Call operations on the 20m, 30m, and 40m bands.
Currently
there is a particular emphasis on JS8Call on the 10 and 12 m band between 00:00 and 12:00 Z, often extending beyond this period.
Olivia 8/250 is used occasionally on the 20m band.
Proposed
band and mode activity
is often communicated on HamSpots: https://hamspots.net/js8/
or my profile on
X: https://x.com/vk6ysf97230
.
Feel free to contact me to discuss or arrange a schedule for a contact.
