Hi Steve,
It is a worthwhile exrecise. You do not only get a wider band width but
also less ripple within the pass band. There is an upgrade kit available
from Elecraft and you have no need to change the entire KSB2 board. I
would suggest 2.4Khz because this will give you good sound quality with
reasonable selectivity. 2.6Khz is too wide for me. For most voice
operation, 2.4khz is the norm.

Question for the K2 listserv.....
I have a K2 (s/n 377) and the KSB2 with the normal 2.1 KHz. bandwidth
configuration. I get excellent audio reports but it is narrow. I'm
thinking of purchasing another KSB2 board and want to make it either
2.4 or 2.6 KHz.
For any who may have made the modification, do you think 2.4 would make
much difference or should I just go for the 2.6 KHz. B/W,. and are there
any considerations when opening it up that far?
Your thoughts........
Thanks,
Steve, AE2G
