My apologises, I cover the LDR (The intensity control) with my finger to
reduce the initial intensity of the display on power on.

Otherwise a nice set. However it resets the standby frequency to 121.9 MHz
on power on.

Thanks, I wondered if that's what you meant.
I discovered that covering the LDR during the day caused the display
to vanish completely when we had a fault:-(
Fortunately for my night flight I still had COM2.

Have you checked the Operating Manual? The standby frequency is
supposed to reset to 121.9 when you switch Off then On. You can then
count the MHz and KHz by counting the detents as you rotate the
control. If you don't loose count then you can set any frequency (NAV
or COM) with a loss of display display. The NAV standby frequency
resets to 110.50 when powered Off then On.
