That said I shared the tracor d-msk-r circuit with the group that removes
the msk. How does it pull that trick off? I do not get how it gets rid of
the msk and leaves the carrier.
A common way to remove BPSK is to simply run the signal
through a frequency doubler (implemented as a full wave
rectifier). This converts 0/180 degrees to 0/360 degrees
which is the same as 0/0 degrees, or no modulation.
