[amsat-bb] Doppler correction between AOS and LOS

Hi to all, a friend of mine, has satpc32 with and SDR. We have the doppler correction, when the satellites it's in AOS, de frequency it's OK, in TCA has (for example) 1 KHz difference, and in LOS has 2 KHz difference.

It's there any configuration to modify??? all the satellites that we found, in AOS has the correct frequency, but in TCA and LOS its not the same as we can see in the waterfall of HDSDR.

Ir i compare the doppler with http://www.amsat.org.ar/pass.htm the frequency has the same between the waterfall and the webpage.

Thanks in advance.
