[arm-allstar] Transmit on Boot or Restart

Are you running PTT active high? I found the same problem. I ended up going ‘by the book’ and inverting the signal with a transistor, but while running PTT high, yes, kicking off any transmit during startup kicked things back in order. There’s a startup_macro option in rpt.conf.

This node is intended for portable/mobile operation so turning it on and off would be the norm. I did want to add one of those shutdown boards as well. Unless of course there is a circuit/hardware workaround that I should consider?

The reason is that the FOB has an internal pullup on the COS line and if you disconnect or disable the radio the line will pull up and simulate keying. This would be shown in the 'V' View option of simpleusb-tune-menu. For the 888 cosfrom needs to be set to USB.
