So I took the radio our of the truck and plugged in into the control head and power supply for my other 800 in the house and it worked fine. Therefore the radio itself must be fine, meaning that the SWR of the system in the truck is high and/or the power supply in the truck is problematic.
I did notice that when the truck is running, the power to the rig is a bit high (14.5V). When keyed on high power and when the truck is off, voltage drops from 12V to 11.6V. I think I might need to invest in a voltage regulator. Any suggestions? 73 de Bud W0RMT
