Well, I guess I won't be buying a 436 any time soon.Riding through Wayne the other day with my 436, and reception was hit or miss. One minute loud and clear, and the next minute garbled. Listening on a 996T in Verona with an outside antenna about 20 feet up, and it's perfect. Very puzzling. On the 436 it shows full signal. The 996T shows between 2-3 bars
I think your issues are indicative of simulcast distortion. When you're in town, you're being bombarded by the four sites at relatively equal levels. The farther out you get, you might only be picking up the closest tower.
Back before the change, two bars was sufficient for crystal clear reception from my job 20+ miles away. Unfortunately I changed jobs before this problem started happening, so I can't say if long distance reception changed. Maybe I'll take a spin by my old job tomorrow and see how I do.
