    Hi Chris,

    Thanks for the bootloader upgrade.
    I applied the upgraded file and 5 to 6 times out of 10 the transceiver turns back on 2 or 2 seconds after I power it off. Once the transceiver turns back on automatically, the frequency string turns red in color and the rotary encoder does not work.
    I guess I still have the same problem. [bootloader version is 0.14 and the firmware is 219.19]
    Could you kindly look into it?

    Thanks and 73,

      Sorry to hear that. I suspect hardware problem. Best to check the voltages on the first regulator, and monitor during power off and on. Something maybe
      is holding the power on, could be the CPU as well, you can check that by cutting a trace, i mean the usual troubleshooting for hardware – by isolating
      modules and narrowing down.

      Hi Darrin,

      Yes, easy for you, but takes ages to prepare, hihi. Almost done with the RF pack, need just to calculate the final price.
