Merge in latest DSP chain #5

Closed K7MDL2 closed 2 years ago

Keith has significant DSP chain update that I plan to merge into this program. Existing DSP work is based off his previous versions.

Completed the swap to the Convolutional filter method. Found a likely problem with Mode Settings. Cannot select USB or LSB sideband properly in the RX_Summer .gain(channel, gain). Seems to be ignoring the sideband selection commands though off and on work (gain = 0 or 1). gain = -1 is not working for some reason. Used to work.

Problem resolved. Typo in test code. Noiseblanker also needed to be initialized at startup. Used the function that sets 2 channels to do that.
