Observations on KAT3 in #1239 Does not always set to 1:1 (think that is to be expected, particularly if close to 1:1 in bypass -- it has discrete values to switch in and out, not continuously variable components like my ATR-30)
Sometimes it will not "get started". This is usually someplace where the bypass SWR is high, like 2.5. It goes through the fast relay cycle, but does not fasten on a solution. In one of these situations, if I QSY to a place where SWR is lower and retry, it will solve it, and I can get to the original frequency it would not solve with two or three intermediate solutions. So it's NOT that it DOESN'T have the range, it's just not finding it in the "solve" if the reach is too far. I don't know of a way to place these solutions in memory (as in the MP) or if it is supposed to be doing that or if that is planned. At the moment the KAT in the K2 has it beat badly on smarts and match range. 73, Guy. Jack Regan-2 wrote: > > Greetings to all, > > > > Here is the text of a note I sent to k3support.
