Got my 2 Wilson's back today. The old, ugly RC works perfectly! It has a huge coil on it, but air tests great, and seems to be stable. The nice looking ATD shows battery strength on the meter, but thats all. No beeps. The IV looks like it's been through hell, but works, with or without headphones. Don't know how long I can swing that one, but I have to take it out at least once. It reminds me of a big Tesoro, and I love Tesoros.
