[Elecraft] [K3] - how option loaded can it get?

[David F. Reed]

I am looking at ordering a K3, and I have begun wondering...

Just how loaded with options can it get?

I will try to illustrate what I mean:

First let us assume no sub-receiver...

   1. Roofing filters - how many can you install?
      Can you get in all the 7 and 8 pole ones?

      Then, adding the sub receiver:

   2. Same question for the second receiver; limit on roofing filters?

   3. What of the General Coverage RX filter; if you might be using both
      non-ham band at the moment, can you fit two in there?

   4. What will I need to do for MARS work?

      Is the General Coverage RX filter required?

      What of the spectral purity outside of the ham bands?

   5. TCXO - assuming one had all this stuff (dual RX< all the roofing
      filters for each rx, TCXO, the ATU, Transverter interface, USB
      adapter, DVR, and so on...  Will it all fit and play together?  I
      realize this sounds kind of funny, but for example, you cannot fit
      every option at the same time inside a K2, right?  Like the ATU
      and the 100 watt module eat the same space...

Just looking to understand the limits...

Thanks
