I have been starting to follow some of the posts on the Uniden threads about the HP-2. I have an HP-1 currently. I am just wondering if anybody has compared the two of them to one another as far as their performance on ARMER. I am assuming that they perform identically, but I suppose it is possible that the HP-2 has a narrower filter and out performs the HP-1 on ARMER. Anyway, has anybody here compared them to one another?
