[Elecraft] Synthesizer Issue

[James D. (Jimmy) Walker, Jr. via Elecraft]

Can someone please give me a summary of this synthesizer issue or a useful link so I can understand all this conversation about new boards. I have a three year old K-3 and a one year old sub-receiver. Do I need these boards? What would they do for me? An off-list reply is welcome since it appears I’m the only one who doesn’t know what’s going on. Thanks.
