LOL! I'm not going to invent the wheel on this thing; it's not worth time, sentimental reasons be damned. At the end of the day, I still have to bill by the hour. A cheaper solution which I've used in the past is to buy complete used receiver on ebay for parts.
My questions were if anyone had successfully used the currently available STKs and this indeed has no protection scheme (hence the request for the print).
In any case, I'm sure one of the Nesda members has an OEM STK somewhere and I'll post a request there if I'm not confident one of the currently available STKs are not suitable.
Thanks for the advice guys.
