I guess I am the only resident of Texas answering the post.
Again, the only TxWarn cite near him is in Athens, Texas, in the middle of nowhere. How would there be any linear simulcast distortion?
The only system in the county is an encrypted TDMA system, Henderson County. He can listen to fire talk groups in his county. Personally speaking, unless I was a firefighter, I would not waste the money on a Phase II radio. A great deal of this system is around Harris County.
If he programs the TxWarn Athens site into his radio, he may or may not hear any traffic on a regular basis. Should signals pass through that site, I am sure he could hear them without any complications.
The highest structure in this "dot on the landscape" small Texas city is the Faulk and Gauntt Building. It has two floors.
The radio in question is more than adequate to monitor Phase I digital. I think it is a long shot.
