Hi Ion,
When you went through the calibration procedure after the upgrade, did you
actually change any of the calibration values, or did you just accept the
initial default values?
If you didn't actually change any of them, then the Raduino will "think"
that calibration hasn't been performed, hence the message "uncalibrated"
will be shown.

After a lont time of using my Bitx40 with Allard's 1.09 firmware I decided
today to upgrade to the latest version 1.27.7
No hardware modifications have been implemented except for the Function
switch that was installed when switching to 1.09.
With the new firmware (1.27.7) I cannot save my calibration. After I power
OFF and again ON I get the same message, unit not calibrated, so I have to
go through the steps of setting LSB calibration, USB calibration, VFO
drive levels, etc. and the starting frequency is VFO A = VFO B = 7.1250
MHz.
Initially I thought there was something wrong with the Nano (EEPROM
issues), but reverting back to 1.09 everything is back to normal and the
calibration values are retained.
Any one had the same experience? What did you do to make it work?
Do I need to make any hardware modifications in order to have the radio
retain the calibration?
Thank you in advance,
