Steve, That is not necessary. The KAT3 remembers the settings on each band, so one can bandswitch from one band to another without need to re-tune. Exception - if you have changed antennas for the new band since the time you did a TUNE on that band, then yes, you will have to re-tune. For those running with multi-band antennas (resonant or not), this is a huge time savings when switching bands - if that antenna was tuned on that band before, just hit the bandswitch and operate, no need to do a tune.
If you operate with a multiband antenna, take some time and TUNE the KAT3 at several places on each band - after that, no TUNE required, just change bands. 73, Don W3FPR Steve Ellington wrote: > The K3 tuner does store it's settings in memory but you must transmit in > order to get the tuner to change to your frequency.
