[Elecraft] IMD and 2.8 hz tx filter question

[goldtr8 at charter.net]

Dear All,

Since I am contemplating adding the sub-receiver I will need matched 
filters for diversity.

Currently I have the 2.7 Khz 5 pole and since filters need to be matched 
I was thinking to go directly to the 2.8 8 pole filters.

So in addition to the matching for RX easily with no offset, will this 
have any improvement in the TX IMD numbers.

Just curious.

Thanks
