Pro-2006: Pro-2006 Front End

[RDowson]

I’m in need of a scanner for airband VHF that doesn’t suffer from front end overload.
I have a strong nearby frequency at 125mhz that blasts through everything on my Uniden 125.
Im told its virtually impossible to overload the Pro-2006. Is this true? Would this be the solution to my problem?

Is the offending frequency actually transmitting at 125mhz or bleeding through there? What is the nature of the offending transmission?

SDS100 vs 436

People using the scanner as a base station. Yes, I realize that. But, not being able to hear simulcast either mobile or portable is a non-starter. I'm sure more portable scanners are sold than base units.

The Pro2006 are almost as good as a professional radio when measured in a high interference environment.

It’s on 125.725. Scottish VOLMET. I need to attenuate between 10 and 20dB to stop it overloading my Uniden

Before buying another random scanner I would pick up a cheap USB dongle SDR and use that to measure the exact level of the offending signal. Or find someone with a spectrum analyzer and do the same. Without that information you will never know what receivers will work. If you measure the VOLMET signal at a moderate high level of say 60dBm then you would have many options. If you receive it at -20dBm or higher then you have a real problem and will have to notch it out.

I have an Airspy R2 that I can use. Do you know how I’d find the signal strength using that and SDR#?

On the spectral display see what the peak level is in "dBm" on your frequency of interest. There might be a curser function that you can use.

Here in LA.. Pro-136 is great for AIR band 108-134MHz not much overload (if any) on the air weather signals

This is the best I can get. Does that help?
