[Elecraft] scopeing filters for eventual diversity receive.

[Richard Hill]

I'm planning to install a sub receiver eventually.  Now I need a CW 
filter.  I'm considering buying two now, matched, with the second for 
later use with the sub receiver.

I understand that the 5-pole filters need to be matched, but have the 
impression that the 8-pole filters do not.

Is that right?  If so, I only need to buy one filter now.

Thanks
