I remember someone told me about this a year ago but I couldn't find the post. I have a Uniden BCT15X and GRE PSR800. The Uniden will pick up the more distant VHF trunk system (100KMs +) away without any trouble. When I try on the GRE with the same Diamond X50A antenna which is outside on LMR400 about 100' up, I get nothing until I turn on the attenuator.
Its confusing to me since then I have to put in attenuation for things in the programming on a case to case basis yet that could change with me moving around in another location. I always thought of using attenuation locally when getting intermod or some other noise, but using it to get in a more distant station? Someone told me in the past I needed to use it, but then that didn't prove true over time as I changed settings in the GRE. I shut off AGC on the system I'm trying to get in but don't know if that would have an effect.
Even when I switch to my Comet Discone outside on the GRE, which is also on LMR400 and 100' up, I still have to put on the attenuator to get the more distant station and the discone has none of the gain the Diamond has.
I remember having this problem in the past, but then I never had to use the attenuator again on the GRE. My card recently corrupted so I had to start over in a way and I'm thinking I put something in differently that I shouldn't of maybe.
