Weird XM Radio Issue

[ylwjacket]

In the mornings, I have started to get No Signal most of the time (I have the blitzsafe and XM box in the trunk). In the afternoons, I get a signal. In the beginning, when I first put it in, I had great service all the time.

I've checked the connections, and the seem fine. I'm wondering if there's dew in the antenna or something. It's not staticky - it just says No Signal on the display.

Anyone have any thoughts?

Thanks.
