Cheap Mobile Random Noise?

[PartsMan]

I have a new Retevis RT-98, a very cheap mobile uhf radio, that will receive random "kerchunk" type noises when driving in my Nissan Frontier.

It doesn't seed to matter what frequency I use and I have tried two different antennas and cables.

Could it just be to cheap? Maybe a ground problem. Truck causing interference?

I have it plugged into the cigarette lighter now.

The Chinese radios lack an effective IF FM Limiter stage so they are susceptible to all sorts of multipath induced noise.

Pay attention to your surroundings. Could be a video sign at a business, or it could be a Jeep/Dodge truck passing by (they are terrible on RFI). I've seen certain places are bad enough they even pop squelch on my Motorola XPR radio.

This sounds more like what I am experiencing. There is an area on my way to work that it is usually bad.

The worst part is that this noise is louder than voice from a real transmission so I end up turning my volume down.
