I've owned a couple TBS-6925 receivers and one TBS-6983.
Even before buying the 6983, I had had success with the 6925 locking transponders with SRs down around 740 (if I remember correctly), however the talk at the time suggested that the 6983 could go down to even lower SR values, which was one of the selling points for my buying that receiver.
Since then, while there have been some features of the 6983 which have made me glad that I bought it, I haven't really noticed any difference with respect to any difference between what one receiver could lock relative to the other.
Recently however, while browsing through the specifications at the TBS web page, I noticed the following:
6925
built in hardware blind scan feature allows scanning of unknown satellite transponder with symbol rate as low as 200ksps
Wide range symbol rates support from 200Ksps to 45Msps
6983
built in hardware blind scan feature allows scanning of unknown satellite transponder with symbol rate as low as 200ksps
Wide range symbol rates support from 1Msps to 45Msps
So, from the specs, it sounds like both can blind scan down to 200 ksps, but that the 6983 apparently doesn't support actually locking transponders below 1000 ksps????
This doesn't make sense. I'm guessing that it's a mistake, however I'm wondering if it could be more related to the ability of software to attain these capabilities.
I can't remember now any examples of transponders I've locked with SR's less than 1000, but I'm pretty certain that I used the Crazyscan blindscan window (ie the one with the constellation display). This window finds the transponder parameters between a frequency bandwidth, then Crazyscan streams that transponder to other programs that can analyze or play the channels. I can't remember ever sucessfully having locked and played channels from a program where you have to enter the parameters directly.
Anyway, I'm just curious whether this is indeed a typo in the specs or is it real, and if real, what differences should be expected in the performance of the two receivers below SRs of 1000.
