[Elecraft] [KX3] KX3 dual-watch working (ahead of schedule!)

[AB8XA]

I read the KX3 filter option has 1,000 Hz and 3,000 Hz filters that give a choice of 500 or 1,500 Hz filtering in CW and 3,000 Hz in SSB. An explanation of how that happens would help.

3,000 Hz filtering is not available in CW and 1,500 Hz is not available in SSB, right?

It seems to me one has to buy the KX3 filter option just to have the same strong adjacent signal rejection the "normal" 3,000 Hz (2.7 kHz 5-pole/2.8 kHz 8-pole) SSB bandwidth the base model K3 offers. 

And if I understand the end result correctly, there is no strong adjacent signal rejection with KX3 dual-watch on like there is with the K3 with narrow filters on both the main and sub receivers. In most cases, the bandwidth will be 15 kHz (CW split > 1,500 Hz).

Is that correct?

Thanks,
