[Elecraft] Automatic 1:1/4:1 balun switching would also work with a KRC2, other rigs

[wayne burdick]

I just wanted to point out that the future "BL3" (a BL2 with a 1:1/4:1 
control relay instead of a switch) could also be controlled by our KRC2 
band decoder. That means you could use it with any rig, not just a K3. 
The KRC2 works with most analog and digital band-control outputs from 
transceivers. (You can see a KRC2 at: 
http://www.elecraft.com/elecraft_products_page.htm).

The KRC2 has 3 accessory outputs that can be configured using a PC 
software application. So, for example, you could route the KRC2's ACC3 
output to the BL3's relay control line, and select 1:1 or 4:1 mode on a 
per-band basis.

The K3 already sends band information to the KRC2 on band changes, so 
you wouldn't have to change or set up anything at the K3. Just 
determine experimentally which Z setting at the balun is needed on each 
band.

We've already got the BL3 designed  :)
