We have an S75 H2S resistant line on one of our trucks and the signal is badly impeded by the line resistance. Can we add some gain to the ANASW board to give us more signal to work with?
Besides the slider bar panel control gains, there are also gains (the true filter gains) that are accessed by Edit-Devices->SDSTIP. Have you also tried increasing those values?
Yep. We have applied all the software gain that we can.
