[Elecraft] [K3] LPF DSP modification

[Grant Youngman]

Hector,

My apologies for being redundant   ... Same question to you, Joe and Merv ..

You have to specify which rev level boards you're talking about.  The "B" rev board was the board before any changes were made.  The "C" board has the LF response improvements.  The "D" board is a "C" board with the LPF.

If we're not specific, none of the comments make sense.

Let me be specific in my question.  If I add the LPF daughter board to the "C" level DSP board, are there ADDITIONAL changes that were made to get to the factory "D" level board or not, beyond what is already in the "C" board?  Maybe Elecraft would chime in on this just for clarification.

Thanks ... Grant/NQ5T
