Stan, For an unregulated supply, try this MPJA unit - http://www.mpja.com/prodinfo.asp?number=17636+PS - You will probably want an enclosure, so look in the left side of the webpage for Boxes and Cabinets.
Or purchase a transformer, a bridge rectifier and a capacitor and build your own power supply. Another alternative is to use a 12 volt battery charger - just add a capacitor (or a battery) to the output. 73, Don W3FPR On 11/2/2010 8:19 PM, stan levandowski wrote: > Bob, I guess I missed this in the FAQ: > > "Analog or switching power supplies themselves are highly susceptible >> to RF.
