I started with a UH078SX-NB, and replaced it with a GME car type instead. I found the hand held to prone to noise, and had to have the squelch wound right up otherwise it was breaking through all the time.. The GME has the squelch level set at 2, and is noise free and receives well. I was able to talk to Rays ailing setup quite well over a distance of about 10Ks. An external antenna may have improved the reception, but didnt get around to trying it..
