Maestro brightness and RX problem and DC power behavior

EA4GLI Member ✭✭✭
edited June 2020 in Maestro

I set the brightness to the lowest level on the Maestro (IMHO even the dimmest it is too bright) but while I TX with the hand mic the brightness goes to a higher setting and dims back down when I release. This is annoying and a waste of battery.


If I turn the backlight off on the physical buttons of the Maestro, and if I TX in SSB for a minute in a rag chewing QSO when I release the hand mic the Maestro becomes deaf for about 5 seconds. Something is going on with the backlight on the buttons because they flash for a few ms just when I release the PTT on the hand mic.

Both problems above happened with Maestro on USB battery power while on WiFi.


Once I am done with the Maestro I turn it off and bring it back to the radio shack. I proceed then to plug it to the 12vdc source and that restarts the device, so I have to wait half a minute while it boots up to turn it off again. That happens if I turn the main power supply where it is connected OFF an ON as well.

    In regards to problem 1 - this is a known issue. No fix in current Maestro release.

    A fix for #1 (#3839 in our system) was implemented and reviewed last week and will be in the next Alpha release.  Barring any issues with the fix, I expect this will make the next public release.

    #2 I have not observed before.  Is anyone else seeing this issue?

    #3 This is a common complaint.  We appreciate the input and will take it into consideration.

    Thanks Eric! 
    It happens with USB battery and on WiFi. Not sure of those variables have anything to do.

    #1 - Tested and dup'ed. If one resets the brightness it is then stable between xmt and Rcv. This seems a minor problem but since Eric indicated the fix is known, forget about it.

    #2 - Can NOT dup. Suspect this is related to the power pack. A V-A meter check is in order.

    #3 - Feature - not a bug. I prefer current implementation.

    #3 I prefer to select when my Maestro turns on. We don't have "Turn on when receiving voltage" on the Flex radio which could be placed in a remote location but we do on the Maestro which is a device that cannot be used unless you are in front of it. Care to explain Tim why do you prefer to have the Maestro turn on when plugged to a power source? Why do you consider it a feature?
