Hello, Can anyone please tell me what "R" (R = 85 on April 8) stands for in the OH2AQ DX Summit propagation data? I realise this is off topic but I am studying propagation which I believe is essential for a QRP station. I know what the "I, A and K" indexes are but the "R" has me baffled; I have searched the Internet but found nothing. Thanks in advance. 73 de Dan VK8AN K2 # 2469
