New version of kalibrate available, v0.4

Kalibrate, or kal, is a program I wrote to help calibrate external
clocks for the USRP. This version will also scan the GSM bands looking
for base stations in your area.

This latest version is much more accurate than previous versions. I
urge anyone using kal to upgrade.

I’d also like to thank Alexander C. for his valuable input, ideas,
and his testing of a large number of alpha versions.

I’d love to hear how kal works, or doesn’t work, for you. Please send
any bugs/feedback/complaints my way!
