Re: [Elecraft] KAT500 AUTO vs MAN mode

Chad, This is a situation that is the result of the KAT500 useing a single detector for sampling the forward and reverse power. In other words, both cannot be sampled at exactly the same time. If the forward power is sampled when the power is low and then the reverse power is sampled when

Hi Chad, Well Don gave the correct reason, as he always does. The nomenclature of auto and manual refers only to the initiation of the tune cycle. Man is in fact automatic after training. Maybe a better term would semiautomatic. It in manual will not initiate a tune cycle

So I got my new KAT500 yesterday, and got it all trained to each of the segments, without reading a single reflector post on the subject (pat own back). Start operating and finding that it wants to tune again in the middle of a QSO (CW or SSB). (Even when the bypass SWR is 1.5) I wrote up a big
