Hi all, I'm seeking schematics, manuals, and advice on peaking a working unit. Its model number is FSTR520BR(FW)1ASP2. Just tearing that model number apart is a workload! It was a commercial base radio, and it's crystalled for 52.525 FM. Right now I'm trying to get as much as possible out of the receiver. It works, but 25 mile away 40W signal radiated through a vertical antenna is just out of the noise on this end. My receive antenna's base is 30 inches off the ground for test purposes.
Advice is requested. Thanks.
