I'm getting a combination buzz and tone anytime I get a ht near the 
1225. It used as a mobile node. The 1225 has been turned down to 1W. I'm 
not getting any interference when the repeater keys up. The ht is 
running at 1W. In the car, the 1225 is in the passenger seat floor. When 
I shuffle around the pi, fob, cables and 5vdc battery, the sound gets 
louder or softer. If I start to tx with the ht and move it around, when 
I get it near the fob and interface, it gets very loud.  Some times, 
like when I first hooked it up a week ago, I had no noise. It acts like 
it comes and goes. I can make a youtube video of my setup if that helps.
