Hello everyone. I am going to buy a IC718 transceiver (http://www.icomamerica.com/en/products/amateur/hf/718/specifications.aspx). I have an existing 12 volt power supply that puts out about 20 amps, I'm wondering if anyone knows whether this will work or whether I really need a 13.8V power supply? The specs say it will operate down to 11.73 volts, although I'm not sure how great of impact that will have on TX performance... Anyways have any experience with this rig??
