I found that the Octagon model Sf-8008 could be used for low symbolrates.. I want to share the first results with you I got yesterday from Helmut DG3KHS.. He wrote me the following:
The SF8008 Single has the Si2166D Tuner and with the actual firmware it is possible to receive low SR down to 250Kb.
You can receive DVB-S, S2 H264 und H265 signals.
To select the QRG the smallest step is 1MHz there it could be possible when there are more stations using e.g. 333Kb that the tuner will look to the strongest one. With a special receiving list you could avoid this. Helmut is using the SF-808 since one month and is satisfied on it. But also told me that the Minitioner is the better choice. Hope that helps those of you who are planning this as a solution for the living room. I expect more improvements in the near future..
