[Elecraft] The Final Build and order for K3

[George Thornton]

I would have only one word of caution with respect to filters.

Replacing filters with a single receiver unit is fairly easy.  However, the process is more tricky when you have a sub receiver involved.

I personally found the sub receiver unit very tricky to install.  The clearances are tight and it was very hard for me to see if things were aligned correctly.  There are also a lot of tricky cable connections.    Although I have built several Elecraft kits I still don't feel comfortable removing or installing the sub receiver unit.  

To change any filters you have to pull the sub Rx unit.
