[ACARS] ACARS listening -HELP-

Thu, 23 Oct 2003 13:06:45 +0300

Hello Carlos

from the equipment you have, I would use only the following:

>SONY ICF-SC1 Scanner
>WATSON WRP-125 preamplifier (Airband)
>RADIO SHACK telescopic antenna

And only if you start suffering from intermod or other interference, would I 
add the ABF125. I would place it between the antenna and the amplifier, just 
to avoid some strong interfering signals to enter your amplifier.

The tuneable receiver filter is unnecessary and it only adds some 
attenuation. You can tune your telescopic antenna itself instead.

With Regards,
Sam
