Having had my HF radio set up for 3 nights now, I have a preliminary observation to make. While I acknowledge my antennas are not terribly effective, I am learning that winter propagation at 35 degrees latitude is a much different kettle of fish to propagation at 19 degrees latitude.
I make this observation by observation on lots of different bands but the starkest difference is on 15 meters where on every evening in north QLD I would be making PSK31 contacts into Asiatic Russia, then further west in Russia and finally Europe as the sun progressed westward. At this latitude the waterfall is blank.
