@steavebba, I think its better to look in the standard way that Enigma2 communicates with cams through caPMT using a private descriptor, instead of trying reinventing the wheel.

The private descriptor 0x86 is the next available after 0x85 that is used as "service type mask".


With above you will get something like the following, that looks good.
 

PYTHONPATH: /usr/lib/enigma2/python
...
[eDVBCAService] injecting private descriptor with frequency 11836000 and orbital_position 192
...
[eDVBCAService] injecting private descriptor with frequency 11856000 and orbital_position 192
...

Good luck.
