Brian, Is the Flex 5000 any good on CW? My understanding is that the delays through the processing chain make it impossible to use QSK.

It is also locked into the processing power that it now has. It is difficult to take advantage of Moore's Law the way it is currently designed. (Moore's Law says that computing power per dollar doubles every 18 months. Anyone buying a PC understands this.) Also, we can't make changes. We are dependent on Lyle and Wayne to have the same interest we do in the features we want and we need them to do the work. This is the disadvantage of a closed environment. I have been on the fence for quite some time and have finally decided to go the route of a Flex 5000 instead of a K3. Even tho' I think that the K3 has a better receiver for traditional modes, I believe that the open software of the Flex and other hardware like the SoftRock will end up offering me more in the long run. Yes I give up some in BDR and IP3 but I get back huge flexibility and expandability with new modulation schemes. I can even hack the code if I want. So it is more appealing to the engineer/hacker in me. But I plan to stick with the K2 as a portable rig. I still really like that little radio. I would love to see Elecraft open up the code for the K2. -- 73 de Brian, WB6RQN Brian Lloyd - brian HYPHEN wb6rqn AT lloyd DOT com _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
