I found this old post here by Satesco regarding a workaround for electromagnetic interference with the TBS6903X & TBS690X cards. Has any anyone been able to duplicate Satesco's result in this regard?
"Due to high sensitivity of the StiD135 demodulator (which is available into DVB cards such as TBS6909X TBS6903X) to electromagnetic interferences and certain currents tensions I have managed to add and solder an extra 22uf capacitor to bridge the 13D and Y1 pins. -by satesco"
