[Elecraft] [K3] K3 memory question

[Don Wilhelm]

Roger,

If your APP connectors have little retention force, they are not 
assembled correctly.
Take a look at the diagrams and pictures of the APP connectors on page 
37 of the XV series transverter assembly manual for a good illustration 
of how the APP connectors should look.  Download that manual from 
http://www.elecraft.com/manual/Assembly%20Manual%20XV50,144,%20222%20Rev%20D.pdf

The blades of the terminals should be securely locked over the spring 
"tongue".  If that is accomplished, the retention of APP connectors is 
quite good.

73,
Don W3FPR
