The only time it is necessary to clear the tuner memories is if you've
already filled up all 31 of them and try to do another. You can avoid
this problem by using the "tune" mode only twice per band - I suggest
once in the CW segment and once in the SSB segment.
The tuner is "smart" enough to track any frequency excursions within a
band based on the information it "learned" from tuning info stored for
the two frequencies within that band, therefore no additional tuner
memories are ever needed (unless you make a change in the antenna used).
Each tuner memory covers only 10.24 kHz. If you QSY outside of the range
for which you stored a tuner frequency in memory (by pressing "tune"),
the "smart" tuner does a good job of guessing the correct tuner
parameters for the new frequency. If you install a new antenna for the
same band, you need not use up another tuner memory -- just press "tune"
with the VFO set at the exact same frequency as you did the first time.
This will overwrite the same tuner memory with the new data.
With that in mind, it is a good idea to keep a record of the frequencies
at which you wish to store tuner data -- and always use those exact same
frequencies whenever you press "tune". This will guarantee that 31 tuner
memories will never be filled up.
