News update from VK9CK Team
They have not got RX antennas to work on 80/160, but they use TX antenna also as RX, which worked satisfactorily.
VK9CK team has been working on a plan to find the best possible time for NA / SA and tested it out during the day today. The plan worked, and they will therefore attempting to call NA / SA during the times when it is possible.
Good Luck and good DX
