[Elecraft] K3 Load fails

[Dick Dievendorff]

Glad to hear that things are going well now.

Sometimes these things are data dependent and timing can play a role  
as well.

It is counterintuitive, but success with one type of transfer does not  
always imply success in all types. Data transfer testing can be very  
diffficult. We have some algorithmic plans that may improve this over  
time, but if the data is getting scrambled we're doing well to just  
reliably detect it!

Enjoy...
