[Elecraft] New beta K3 firmware!

Fri Sep 21 19:38:40 EDT 2012

Hi All,

I dream one day to see Elecraft building some kind of expansion slot to accomodate more filters. Now all my slots are filled, 200/400/2.1k/2.8k/FM x2 for both RXs so no more free slots for AM or any other filter. I don't care too much abt AM filter but I would like to squeeze two more filters, maybe a 800 and 1.5k filter. Wayne, do you see technical possible to accomodate some sort of optional expansion filter slot? I am sure many of us will welcome such feature. If will ever be such an option but me on alpha/beta testing on top of your list.

Tnx and 73 de VE3GNO Daniel

*Hi Joe,

Thanks for the explanation. I can now 'see' what you meant and it does seem
logical.

I too have all 5 filter slots in use.

'Learning all the time'...:-)

73's Joe and thanks again.
