[Elecraft] sub filters

[Dick Dievendorff]

I assume you're going to leave your main board alone.

FL1 = 13 kHz
FL2 = 6.0 kHz
FL3 = 2.8 kHz
FL4 = 1.0 kHz
FL5 = 250 Hz

Were it my rig, I'd install the sub's filters in FL1-3;

FL1 = 2.8 kHz
FL2 = 1.0 kHz
FL3 = 250 Hz

UNLESS I had plans for another filter in the sub in the near future.  If I
thought I might acquire a 1.8 kHz for the sub real soon, I'd leave a hole
for it.

I think it would also work just fine to put the sub's filters in FL3, FL4,
and FL5 so that FL4, for example, is the same width in both main and sub.

Almost done with the KRX3  :)

On my main board I have all slots filled with FL1=13K FM & FL2=6K 
AM/ESSB FL3=2.8, FL4=1 & FL5=.250

For the Sub I don't need the AM or FM filters and I have matching 
2.8, 1 & .250 filters 

The sub instructions say to put the widest bandwidth filters nearest 
FL1. Now I've got to think & that always hurts...

So do I fill slots 1, 2 & 3 (with the 2.8 in slot 1)?

or do I fill slots 3, 4 & 5 (with the 2.8 in slot 3)?

Thanks
