Hello.
I would like to plug my g2 radio with a 4.8 V power supply. I plug the -/+ pins but nothing happens, no way to start it. I found the power pins with a simple voltmeter.
I had saw this explanations: http://brmlab.cz/project/sdr/tetrapol/g2 but I don't understand if I have to use an existing battery for "id". I have 2 batteries that have worked but now empty.

I would like to have some experts advices.

Best regards.
