Thank you Lou and Martin.

Will try and take a look. One more thing is there any extra to do if the PSK signal is +-67 degrees instead of nomal 90 degrees or the PSK demodulator just handles it as usual.

That sounds correct. I know hams sometimes do this to get better
transmissions when using their HF gear.
