@G0MRF The F1OPA module alone draws 89 mA. When switching on TX on LimeSDR and gradually increasing drive, nothing happens until about 50% drive, and then current draw from F1OPA goes DOWN (!), 70 mA at full drive.
G4SDG . Thank you for the heads up. The Console is a great piece of softwre, but can be a pain to use (mine freezes two or three times per session anyway...). Concerning TX power, how will I be able to tell, not having a power meter of any sort for 2.4? Please remember I am using a LimeSDR mini, which only has one antenna connection for TX and one for receive. TX ant does not seem configurable.
