[Elecraft] [K3] Ease of installing modules at a later date

[Jim Lowman]

I think I may have asked before about the need to match the filters in 
the sub-receiver with the main receiver, so please forgive the redundancy.

Slightly different question:  How difficult is it to install the 
general-coverage bandpass filter and second receiver after the K3 is 
assembled?

I was going to order the sub-receiver and the appropriate filters, but 
decided to put that on the back burner until I get more comfortable with 
operating the K3.
However, I am considering the bandpass filter so that I will have 
general coverage.

Any advice appreciated,
