> Does any body remember or used the SINPO or SINFEMO code reports...!!! I remember to have used this report code (also called SINFO) as a BCL/SWL some 30 years ago. The meaning was: S - signal strength I - interference (i.e. qrm) N - noise (i.e. qrn) F - fading (i.e. qsb) O - overall impression SIN_P_O is the same, but I can't remember the meaning of the 'P'. 73 Joe DK7VW [N7VW]
