[Elecraft] K3 sub-receiver usefulness?

[James Sarte]

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?

 

73,
