Ashok,
I think you are on to something.
Although the voltage levels where the break point falls may vary,
I have verified your findings here.
Below about 2.2V tune voltage, my FN button stops working.
Above about 2.73V the FN button stops working.
In between it seems to work fine.
And my unit starts scanning lower in freq at about 2.0V and starts scanning
upwards at about 3.0V.
The FN button does not work in my unit when the frequency is changing, but that
would seem to be by deliberate design.
However, the FN button should work at any voltage level that does not produce a
change in frequency.
So it does indeed seem there is a small error in the code.
Thomas and Farhan, can you verify this with your units, with v0.03 uploaded?
Thank you,
Wayne NB6M
