[Elecraft] K3 sub-receiver usefulness?

[Johnny Siu]

Hello James,
 
May be not a direct answer to your question.
 
Sub-receiver is useful provided that you have installed it carefully and there is no birdies.

Hello group,
 
Someone mentioned in one of the reflector emails that the new firmware under development will allow independent band switching/monitoring between VFO’s without a sub receiver.  Am I correct in my understanding then that without a sub receiver, this firmware will allow tuning and monitoring of separate bands?  If that is indeed the case, can someone please clarify for me how that can accomplished with a single receiver?  
 
On a separate note, apart from diversity receive, I’m curious to know how other people are utilizing their sub receiver?  The reason I ask is I’m finalizing my purchase of a K3, and am trying to determine whether it’s necessary to fully load up both receivers now.  At this point, I’m ready to purchase 2 general coverage modules plus 2 each of the following filters: 250KHz, 400KHz, 2.8Khz, 6KHz, 13KHz.  I’d like to have the ability to monitor PSK31, FM or SW broadcast on the sub, while monitoring phone or engaging in a phone QSO on the main; both receivers being on separate bands.  That’s just one example.  Another could be to monitor SW broadcast on the main while listening to 10m FM on the sub.  Do I need to install the AM or FM filters in the sub to monitor SW or FM or can the sub’s DSP take care of it?
