O/T: NO radio reception!! (well a little)

[BluebyU]

I'm so frustrated!! The stupid radio in my Loyale won't pick up any stations once the car warms up. This is a recent development and I have no idea where to begin looking. It worked fine up until about 2 weeks ago. When it's cold, it works fine. Once it starts to warm up, the reception quits.

Any suggestions? The car is my 2nd car, so I don't really want to spend a bunch of money for a decent radio for it. Although a cheapie from walmart is looking better and better.

One other question. Now that we're getting lower temps here, the engine in the Loyale seems to roar when I start it. It sounds as if the fan kicks on the minute the car starts. I press the gas pedal a bit and it goes back down to a lower idle. Should the fan be coming on as soon as the car starts? I never noticed this in the summer. It runs great, and the temp gauge is where is should be. Should I be concerned?
