I have a Cobra Ultralite antenna and the KAT2 tuner in the K2 finds a match on all bands (with a BL2 in the 4 to 1 position). The K3 ATU is a similar type of tuner. The great thing about the built-in tuner is that it remembers the settings for each band which makes changing bands very easy. This is extremely convenient. Most external auto tuners need some RF power before they "remember" the settings for that frequency range.
You also may want to add or subtract some feedline length to help out those problem bands. I added 18 feet to the feedline and this brought all bands (including WARC, not including 160) within the range of a Johnson Matchbox tuner. I still prefer using the balanced tuner over the unbalanced tuner and balun. But the K3 may change my thinking when it arrives (ordered in December). John W2XS I need a tuner that will hopefully tune every band to <= 1.5:1 on a Cobra multiband dipole antenna. The built-in ATU in my TS-850 has difficulties with certain frequency ranges within a couple of bands. Should I go with the built-in K3 ATU, or remove that from my order and just pickup an a decent external LDG tuner? Any advice would be greatly appreciated. -- View this message in context: http://www.nabble.com/K3-ATU-specifications-tp16607551p16608901.html Sent from the Elecraft mailing list archive at Nabble.com. _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
