> Jean-François Ménard / VA2VYZ Jean-Francois, I believe that with the PA installed, even if you shut off the PA's power supply and run QRP power, the current drain will be greater than the K2 QRP version. I don't have my schematic in front of me, but I believe there are circuits in the PA that draw current from the RF board of the K2. You can expect something like 150 mA quiescent current drain from the PA. Therefore, if you are going to operate in the field from batteries, then you should physically remove the PA and replace with the QRP top cover to achieve the (approx) 200 mA receive current.
