Re: [Flexradio] Are there Any 2.4 khz Spur Problem Updates?

Jim,

Yes, the automated spur reduction algorithm has been completed and is in
alpha test as of last week.  This topic is covered on the FlexEdge reflector
since it is still alpha code.  It is working very well in our internal
testing.  Many other improvements have been implemented in the PB-PAL code
as well.  More to follow.

 The ALC overshoot problem and the problems it caused with amplifiers was a
 main concern of mine after buying the Flex 5000.
 Glad to see this problem is apparently fixed. I will check it out tomorrow
 with my amplifier.

 Another MAJOR concern of mine was the 2.4khz spur problem, particularly on
 160 mtrs. You made a comment last month that these spur problems were close
 to being fixed.
 Could you update on this as this is the only major concern I have left with
 the Flex radio.

 That is job number one after the changes to make sure we didn't mess that
 up.  I think we are in pretty good shape now.  Eric made me comment every
 single line.  What a great idea.  In so doing, we corrected four buglets,  a
 serious bug,  and optimized the code considerably by doing things like
 eliminating redundant branching.

 So much for my snobbery about annotation.  I surrender to the inevitable.
