Sounds like a very nice RF setup. I know of a station not far from me that's 
using the preamp to which you refer. This setup however, will do nothing to 
eliminate interference when the interfering signal is the same as the desired 
Marti signal, which  is the scenario I've seen way to often in medium and large
 
markets.

I think the days are numbered for RPU channels being used for mission 
critical remotes, especially in the large markets. The particular station I was
 using 
as the reference, also had the tower rented out to a two way company. This is 
also common. ironically, interference caused by the local two way stuff was 
virtually nonexistent. That was a lot of the frustration because it took a lot 
of persuading to get that local two way system off the hook, because it seemed 
so logical to blame it. Once it was determined that the interfering signal 
was monitored away from the marti receivers and found to be STRONGER than it wa
s 
at the marti receive site, was the real offending transmitter found.
