[Elecraft] IOC Firmware REV Question

Sun Dec 29 09:02:00 2002

Hi

The 1.07 IOC is required for the KAT100 not the KPA100. The KPA100 will work
with 2.02A and later although I think you need to upgrade the SSB controller
to 1.07 also. The KAT100 needs 2.03d or later and 1.07 IOC. When you do this
firmware upgrade the K2 will do a hard reset so all of your filter settings
and other user settings will need to be re-setup. The reason for this is to
save room in the main controller. Some of the lookup tables are now in the
IOC and transferred to ram over the AUX buss when needed rather taking up
room in the main controller.
