Linrad Setup parameters of VK2KU

Linrad Version 2.43

 

Warning:
These parameter values are those I am using today for JT65B EME  on 144MHz with my SDR-IQ. Tomorrow I may change them.
Just because they work for me does not mean that they are optimal for a different application using different hardware.
