>>>I cannot understand why JT9 is used so little on 160 thru 20. JT65 >>>is a VHF mode. Not really, there are different 'flavours' of JT65, on HF it's JT65A. As for JT9, there reason is that JT65-HF, and its derivatives, such as the one maintained by HB9HQX, is still used by a substantial number of people. JT65-HF does not support JT9. 73 de Vince, VA3VF
