[Elecraft] Sub receiver installation

[Ed Muns]

> How difficult is it to install the sub receiver in the K3?

Depends on one's skill in such things.  Some people call it trivial and
others think it is a big deal.

> How much time does it take?

As reported on this reflector, experiences have ranged from 1.5 to 4 hours.
The instructions are excellent, but they have to be read and followed
diligently.
