Me too Ross, others in ZL also .. don't remember any 23 cm contact (ZL/VK) so far this year .. mind you this year is not over yet! I'm watching carefully around November / December for starters ..I also look forward to trying out my upgraded system with circular polarization on terrestrial DX during the coming summer season, running higher power and improved receive gain compared to my last 25 or so years using the previous setup.
And congratulations for 23 cm EME at 5.3 km (SP) to young Mark VK2AMS .. I take my hat off to you both for that one !!
All the best from ZL...
