There have been discussions about the current draw when biasing the 6000 final amplifier, see https://community.flexradio.com/flexradio/topics/current-drain-on-6300?topic-reply-list%5Bsettings%5... for one.
Does, or can, the final amplifier be bypassed and not keyed up on transmit? The preference would be via an API call from SmartSDR Tx setup, or by a physical process such as removing the final and jumpering connectors.
Last FD we ran 3AB with (literally) a ton of batteries but the Flex was left behind due to exceeding the current budget of 7A for rig, computer and monitor(s).
It would be nice to flip a switch on SmartSDR (or Maestro) to turn on/off QRP reducing the associated battery draw.
