TBS 6983 Low and High SRs

The TBS 6983 card is the best card so far and as hard core DXers me (Sato) and Peon (aka Onacila) would like to prove the card`s capability on the following examples. We test our hardware to the maximum on various bands as we can cover C (3.4-4.2 + 4.5-4.8 GHz), Ku (10.75-12.75 GHz) and Ka (18.2-22.2 GHz) plus X band (7.25-7.75 GHz hardware is ready).

Anyway, with TBS 6983 on Windows 7 (32 bit) the lowest SR we have been able to get so far is SR 128 and the highest is SR 60000 KS/s. Both stable and hassle free on a 2.5m prime focus dish by using XMW 9216HDF and NJR 2842S. SR 139 KS/s have been received in C band by using a Norsat 8115F LNB. I guess these are current limits in orbit at the moment, but definitely not the TBS card! If there`s anything under or above those SRs, I`ll post screenshost here asap.

Additional details can be found on lyngsat.com or flysat.com where our and other DXers` updates are posted.

Here`s one more example how brilliant the TBS 6983 is.
The screenshot is from reception of Eutelsat 12 West A @ 12.5W, frequency 12555 Vertical. TV signal is usually transmitted in CCM mode (so called Coding Mode) and ACM/VCM is mostly seen for data transmission, when 16-32 APSK modulation is used.
This picture is a perfect example of a "multistandard" transmission when several modes are used at the same time (ACM VCM + MIS) and a brilliant card design that can handle all these requirements without any problems. Simply superb!
