A few people have asked me about the SINPO reports given by UK 5MHz operators when making contacts. The interpretation used is as follows:

  1 2 3 4 5
Signal S2 or below S3 or S4 S5 or S6 S7 or S8 S9 or above
Interference (QRM) S9 or above S7 or S8 S5 or S6 S3 or S4 S2 or below
Noise (QRN) S9 or above S7 or S8 S5 or S6 S3 or S4 S2 or below
Propagation Disturbance (Fading or multipath/doppler) QSB>6
S points		 QSB=6
S points		 QSB=4
S points		 QSB=2
S points		 No QSB
Extreme Auroral Strong Medium Slight No multipath/Doppler
Overall (QRK) Extremely difficult Poor Medium Good Excellent Quality

This information can be found in the Operating Procedures published by the RSGB (see LINKS)

NOTE: I have heard UK hams giving SINPO reports to bewildered non-UK hams - bear in mind that non-UK hams may not be familiar with this type of report.
