Jose,

Sorry for the slow reply I am still traveling. Hears what I think would be good trouble shooting, to get this sorted out. First does the performance of your second T2 math that of your first. Or is it about the same?

If the answer is about the same, then let me test an IRF-6, including antenna so I know the range. I will make sure this unit performs equal to my reference unit. Then I will ship it to you to see how it performs. This will eliminate the IRF-6 as your problem and then leaves noise as most likely problem. I don't think you could get 2 bad T2's? Wont be able to get this done until tomorrow night as I will be spending my day in airports
