IA-6 stuck transponder
I was reading back into this post where the pansat 3500 was sticking on a transponder for a few minutes. My 2500A and Fortec ultra do the same thing.
I can't remember the tp frequency or s/r but I remember that one would really slow my receivers down to the point I thought they had locked up.
after a few minutes it moved on without finding anything scrambled or clear.
The data stream from that tp must contain code that keeps the cpu's in these fta receivers on the threshold of detecting a usable channel yet there is nothing their.
my second theory is it could be a channel that the uplinker is using some "poor man's scrambling" scheme by using a slightly modified mpeg-2 stream. Just simply removing or inverting a couple of bytes from the stream.
yet not actually using a commercially available encryption system like all of the popular ones used by large commericial program providers.
