Observation 2187058: CAS-4A (42761)

Regarding Observation 2187058

Have tried running this through HS-soundmodem and got nothing.
Any ideas?

Depending on the used antenna type and the resulting beam width, link losses have to be taken into account on low elevation. You need much more gain of your antenna for this elevation ( it could be possible for example Yagi 4x16 elements ).
