Re: Power Supply Woes Solved!

Yes, Jeff, adding small value caps will shunt (short) the RF to ground I 
recomend using a .1 uF non-electrolitic. That should do the trick.  
Larger value caps, such as electrolytics, also have internal inductances 
that can act as an RF choke and block the signals from being shunted to
