Hi Wayne:
Thanks for the quick response concerning the KX1 AGC.  I'm currently
building my second K2 after just completing my second K1.  I'm always
thinking about a future project.  The KX1 has caught my eye!
By the way, thanks for making such nice radio kits.  The radios are so well
designed and the support by Elecraft and through the reflector is superb!
