I have FT-847 to send 12VDC to them. I currently have an SWR meter between the 847 and the preamps. Can I feed power through the SWR meter safely? The SWR meter is an SX-1000 by Diamond.\n>\n> Thanks,\n> Mike\n> kb8zgl\n> _______________________________________________\n> Sent via [email protected].
