Hi, Thanks for the comments this morning.
I'm not looking for something huge, maybe in the under $200 range. Just enough for the Thunderbolt, laptop, and Agilent 53131A counter. I'd like a little headroom though, as I may add another Thunderbolt or a rubidium standard someday. I do like the 12 V battery idea. I run my ham gear off a 12 V gel cell (I'm mainly QRP so a 32 Ah cell works for me) and I have a 12 V distribution system with Anderson Power Poles on my operating bench. I do a lot of VLF and LF listening but my antennas are outside. Nothing at this time above 2 meters. I live in a very quiet rural area on top of a mountain in Tennessee. So not much man made noise at all and I wanted to keep it quiet emission wise. Thanks for all your help.
