one transponder does not work while using the default firmware it works without any problems. Any idea what might cause that and how to fix it? It is on the 23.5 on this transponder: http://en.kingofsat.net/tp.php?tp=1159

The vertical transponders work properly on that satellite. But what I think is so strange is that if I boot to the default firmware it works fine so then the hardware is working fine I suppose.

Any suggestions? When I do a manual scan on the specific transponder it finds nothing at all.
