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

[Stan Gibbs, KR7C]

In trying to load this new FW version, I discovered that there appears to be
an interaction between the proper operation of the serial interface and the
"Sleep When Idle" option.  If the oscillator is not running due to the
timeout enabled by this option, as can be seen on my P3 at 28.004 MHz, then
a serial command does not work reliably and firmware updates produce an
error message about an incorrect device.

>From a quick and dirty experiment, it looks like the first typed "an;"
command restarts the oscillator but produces no output.  The second command
also produces no output.  The third "an;" produces the expected "AN1;"
response.

After disabling the "Sleep When Idle" option, the firmware load was
successful.

Has anyone else seen this?
