Wondering if anyone has noticed on their IC-902 an unusually "high squelch" where Walkie Talkie reception is involved. What I mean is that I lose the Walkie Talkie emblem on the screen many times in places where when I had strictly a "pure" Nextel phone I had a reasonable signal. Of course, many times that I did have a decent signal, I still had folks tell me that they couldn't clearly hear me on a walkie talkie call...that I sounded garbled...so, I'm wondering if perhaps the IC-902 is merely required to have a stronger Nextel signal so as to insure a successful walkie talkie call than perhaps a pure Nextel might allow...hope this makes sense.
