I just heard from Mako that the 1.65 engine is the same as the 1.64b I've been beta testing for a few months. This engine fixes the problem WriteLog users had with 1.63 and 1.64 where the transmitter would key when an F-key was pressed, but then quickly unkeyed. This problem would fix itself after a few seconds of time. 1.65 should be good to go. http://www.qsl.net/mmhamsoft/mmtty/ 73, Don AA5AU http://www.aa5au.com http://www.rttycontesting.com
