The A channels (RC channels) are actually pretty popular. I’ve noticed truckers using 19A (27.195 MHz / 27195 kHz) in the past, have even heard operators using FM voice mode on 27.195. 27.045 MHz (channel 7A) is pretty close to the mess that is 27.025 MHz but I’ve also logged activity on 26.995 MHz (channel 3A).
It would appear there’s another sporadic-E opening in progress...according to DXMaps anyway, E-skip activity on 10 meters and 6 meters this morning. That would mean that 11 meters / CB and VHF lowband 30-50 MHz are also open.
