Hi guys, a question.

We were on a drive back from The Coromandel Peninsula, through the Waikato, and finally back to Auckland.

On the way back, we tuned into the local Classic hits radio station for the region which is on 98.6mhz.

I was amazed that the signal didn't drop out over the Bombay Hills, and when we got to our Destination in Onehunga the signal was still going strong.

I checked the display on the Car radio unit, and it was indeed on the Waikato frequency. My question is, is this a normal occurrence, or do some head units have some sort of automatic change over?

Was it just the weather conditions, or is this normal?

thanks
