[Elecraft] K2: DSP for CW ?

[Simon Brown (HB9DRV)]

Thanks to you and all who have replied. Due to Elecraft's modular design I 
could always buy this later - but for $219 I would probably buy at the same 
time.

[1] Does the DSP2 add significant extra current drain in RX? This is an 
important criteria as I'll be using batteries / solar cells and will have up 
to 6 AH of battery with me (2 x 3AH).
[2] Would the T1 be OK with the basic K2 (I assume so)?

Hope to have K1 finished late next week so K2 would be a Christmas / New 
Year project.

I will look for extra / larger batteries at Friedrichshafen 2006 but my 2 x 
Ni-MH 3 AH are very good and light. I would like to be able to use my IC-703 
portable but it requires up to 600 mA on receive.
