[Elecraft] Need volunteers to try an even better version of KAT500 firmware (rev. 1.63) -- more accurate initial tunes

This is definitely high on my list, Bob. Thanks--

>>> Hi all,
>>> We just posted a new beta-test release of KAT500 firmware (rev 1.63) that does a better job on initial tunes than the previous release (1.58). We'd really like to get this firmware into production quickly, but to do that we'll need some testing help.
>>> If you can spare a few minutes, please do the following:

>>> 2)  Install KAT500 rev. 1.63 (follow instructions for beta releases)
>>> 3)  Erase memories on at least one band where the tuner has to work to find solutions (that?s 160 through 40 meters for most of us)
>>> 4)  Do some full-search tunes.
>>> The KAT500 should find very good tuning solutions (within its specified impedance-matching limits, of course). Please send me your results.
