My Elecraft KX3 transciver. You can also see my N8WTT Voltage Regulator which always presents 13.8 volts to my radio no matter what the power sources voltage really is. This helps with keeping voltage up as batteries run down. It will give you extra time. With the KX3 that means running the radio at 12 volts with the regulator in place. In the photo you can also see my FT-950 (right), my FTM-350/AR, my Auvio speaker below the KX3. The KX3 sits on my Yellow (mustard?) Pelican 1160 case, you can see part of the other 1160 Clear case to the right of the KX3 (there is a wooden cross on it). The N8WTT Voltage Regulator sits atop one of my 7ah batteries. Right above my KX3 you see my LDG meter and my Diamond DX400 meter. The photo is too dark to see my Powerwerx Power Supply between the 7ah battery and the yellow 1160 pelican case.
