Crystal filter locations on main and sub receivers?

K2QI
Dear group,
 
I know that matched crystals are required for diversity receive, however should the placement of the crystals in their slots also be the same between both receivers?
 
For example, I will have 13, 6, 2.7, and 500 on the main starting with FL1 to FL4.  The sub will only have the 13, 2.7, and 500 filters.  Should the 13, 2.7 and 500 filters be placed inFL1, FL3 and FL4 respectively while leaving FL2 blank to match the locations of the filters on the main receiver?
 
73,

P.S. Ordered my kit today, and already got my invoice.  I was told it should be shipping tomorrow!!!

Either will work just fine. Your choice. Just configure the radio to match where the filters are physically plugged.

 

The 13 kHz FM filter MUST be in Main FL 1 if you wish to transmit FM.

 

 

Sounds like a nice radio!

James,

The filters can be put in either way.  I just think it is easier to put
them in the same slots for the main and sub - it is easier to remember
that FL3 is the 2.7kHz filter that way since that fact applies to both
the main and the sub.
