Hi Guy,
A song by the Boomtown Rats about Mondays, I remember :-)
Good to hear (well not for bug tracing ofcourse ;-) that you did not have any of these issues.
Regarding the power on/off, it seems that the radio body had "crashed" when this occured.
May be that also explains the clock reset. Strangely memories and Dstar settings,etc were all still intact. Could have been a short mains power drop or an encountered FW bug.
First I will bring the radio back home and check without RRCs on the speaker/HP issue, may be impedance of the headphones is critical for the unit to recognize they are inserted.
Dont really want to bring it in for inspection over these small issues, it is a nice rig.
