Bob, congratulations on your ability to send high speed CW and to place high in contests. I respect you for these accomplishments and especially respect you for your contributions to the Flex radio operations.
I had noticed that Flex has removed most references about ability to QSK in their advertisements, which was removed after I bought my Flex 5000. Thanks for your explanation of how fast the T/R changeover is. However, I would like to be sure I am not confused about what you have said in this recent note. I may be incorrectly reading that working on the software issues that would allow QSK is a low priority, and it seems to be that you are implying that the other things you mention are going to be fixed in the PSDR 2.0 release first and seems to imply the repair of the lack of QSK will be put on hold. Your statements seem to imply to me that it will be after Dayton and after the release of PSDR 2.0 before this issue is addressed. Please correct me if I am wrong. I am not a software engineer but I do understand that it may be complex to accomplish this fix. I am simply a user of the radio and would like to see QSK work. Although no radio is perfect, almost everything else about the radio is super and I am certainly enjoying using it. 73 Jay W5SL Austin Texas On Feb 22, 2010, at 1:23 PM, Bob McGwier wrote: > You would be.... wrong .... about some of the things you say. > > When I operate outside of my car.....
