Hello there, How about the tactical mode / option 2750Hz beside the 500, 2300, selection. Most of the RMS's in Australia are using this mode for Vara HF Winlink. Would be a great option to have. Up to 20% better performance than 2300Hz I really like VarAC and the way its heading. Hoping more people get on board. It gets lonely at times putting out CQ's with no connections. FT8 gets a bit boring. Keep safe. Cheers Mark VK3ASC / VK1MK
