[Elecraft] K3 Beta 5r10 and LINK

[Brendan Minish]

Johnny,


I had the 7800 for a while, the reason it can't do diversity is that
since the main and sub use different IF frequencies there is always a
small (Sub 1Hz frequency different between the 2 receivers due to DDS
rounding error differences between the main ad sub synths  


Neither link or diversity are 'going away' see the release notes 

* EASIER DIVERSITY RECEIVE SELECTION: A regular hold of SUB now goes
directly into diversity receive, without first having to go through
"LINK". This should benefit most users of the KRX3 sub receiver, since
few use the VFO linking function. Those who do use VFO linking can still
turn it on by setting CONFIG:VFO LNK to ON. This menu entry can be
assigned to a programmable function switch for easy selection if
desired, eliminating the need to bring up the menu. Note: Remote-control
command "LN" is another way to accomplish VFO linking.
