[Elecraft] New Firmware Release!

[Dick Dievendorff]

Hi, Jim!

The TCXO screen has a number of "edit controls" which are text boxes that
you type numbers into.  

The "Apply" button is enabled (not dimmed out) whenever any of the edit
controls have a value that is different from the value read from the radio,
and all the "edit controls" contain "valid" data.  

The K3 Utility accepts only certain characters to be entered into the edit
controls, and there are range checks on each of the controls, to avoid
wildly incorrect values (off by a factor of 10, for example).

If you change an edit control and move to another control (by tabbing to
another control or clicking some other button), the K3 Utility "validates"
the text you've entered. If any edit control contains "invalid" data, the
Apply button is disabled (dimmed).  If you leave an edit control that
contains "invalid" data, the utility beeps a bit to alert you, and the Apply
button at the bottom of the page will be disabled.  If you go back and
correct the "invalid" edit control, the apply button should become enabled
again.

I'd recommend you change a few items at a time, and save (press the Apply
button) after entering one or two just to see how that works.

The ten Frequency Delta (ppm) edit controls expect a number between +9.99
and -9.99.  You don't have to enter a + sign, it's assumed.  The controls
expect no more than two decimal places.  0.25 is fine, 0.250 is not
accepted. 

I've only seen a couple of TCXO data sheets, but when I wrote the code I
assumed that the "PPM" value would be specified to two decimal places.  Is
your TCXO data sheet different?


Thanks,
Dick, K6KR

without a hitch.  But when I tried to save them to memory, I could not.  I'd
close this feature and then reopen it.  The numbers had returned to what I'd
guess were the parameters used as "baseline" by the factory.

something coming in the future or am I'm doing something wrong?  The "link"
to save these numbers "disappears" by the time I've inserted the numbers.
