When ALT1 or ALT2 are invoked, there are "wings" added to the bandwidth display. This does not distinguish between ALT1 and ALT2. It only indicates that one or the other is in place. The LCD hardware is fixed with the first 'I' of the I/II icon always on. That is, it is on all the time when the K3 is powered up; the firmware cannot turn it off. Therefore, these display icons cannot be used for the ALT1 & ALT2 indicator. They were expressly designed to support the PRESET I & II function and need to stay with that function. > I really doubt that there will be a new front panel showing > these filter "fixed presets" for some time to come.

This is not true (that PRESET shouldn't have labels). And, it is why either 'I' or 'II' is always displayed. This tells you that the current filter settings will be saved as PRESET I or PRESET II when you select the other preset. Or, another perspective is that you are changing the displayed PRESET values as you change filter settings and they are "saved" when you then select the other PRESET. It is designed as a quick, convenient way to have two temporary filter settings to toggle between on a signal. (It would be cumbersome to do this use case with the NORM & ALT1/2 feature because of the required SAVe.) NORM has a different purpose and ALT1 & ALT2 were added to allow user definition of these stable starting points for filter settings in each mode. They do not change until the user explicitly does a SAVe operation, so they can be depended on to remain stable. If you've twiddled the filter settings (or, are not sure what they all are) and want to quickly get to a known starting point, use NORM or one of your saved ALT1/2 settings. This use case is not addressed with the PRESET feature. Think precisely about how you would like to use filter setting memories and then select one of these two features to match each use case. For different uses, one or the other is best suited. That's why there is a choice. Many people will use both features, at different times, depending on what they are trying to do with the radio. 73, Ed - W0YK _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
