I got the PWRgate PG40S which has great reviews. This will allow an AC and a DC hook up at the same time without messing up the radio. If the AC side loses power the DC side powers the radio without any interruption.
The power supply is the same brand I use on the base station, a Samlex SEC 1223 with meters for the box I opted to get the model without the meters. Surprisingly this power supply generates almost no heat in my usage of the radio. Maybe during long operations it may produce heat but I've yet to even hear a cooling fan or feel heat from it. I hope that I will have the same results from the one I am using for this project.
The cost for these two devices was $248 including the shipping. This however should be the last of the big purchases.
Another device I am adding to the radio box is a small AC line filter and protector, while it would be desirable to run off batteries when the AC becomes unstable, however sometimes that is not always an option. Especially when you are on AC power when it becomes unstable.
I have chosen to use the APC P1T 1, which has a low cut off. The device has lightening and surge protection, and noise filtering. This will provide minimum protection for the power supply and subsequently the radio.
