The SINPO report
The SINPO report (Signal, Interference, Noise, Propagation, Overall) is manly used by SWLs (Short-Wave Listners) and describes the quality of a radio communication with a five digit number.
This report is more accurate than the RST that is very often just 59 and therefore doesn't really reflect the quality of the received signal. SINPO reports are very appreciated by broadcast station for the quality of the feedback information.
In this report all digits are from 1 (worse) to 5 (best) according to the following table:
| Signal | Interference | Noise | Propagation | Overall | ||||||||||||||||||||||||||||||||||||||||||||||||||
| Strength of the signal received. | Interference from other stations. | Presence of atmospheric or other noise. | Fading characteristics of the signal. | How well the signal is received. | ||||||||||||||||||||||||||||||||||||||||||||||||||

The SIO report (Signal strength, Interference, Overall quality) is a simplified version of the SINPO report that is sometimes used.
Now let me tell you what is this !.Did you listen to short wave radio,then this can be a new hobby for you..ie.D'Xing .It is a simple hobby of collecting QSL cards from around the world.What you need is a good short wave radio with all the broadcasting bands in it.
Whenever you stumble upon a new radio station, note down the quality of the reception (in numbers grade) per the above chart.. if your points are 4 5 4 3 4, it means your reception is graded good overall..Study the table above and try to grade a station in the relevent numbers to get the SINPO.Dont forget to note the name of the station, the time(GMT),the programme (title/name/host etc.),now with all these details , with your radio model and brand name,place of listening write a post card or a letter to the station.you may think it is a costly affair,but I have an idea to send these letters to foreign lands..Take out the Manorama Year Book or search the net for the Embassy address of that country from where you listened to the station..and send a post card(forgive me ,that is what I have done in the past.Now there is e.mail).After verification of your details with the stations logbook ,they will respond with a QSL card-which means "I acknowledge receipt." (colorful post card).Collecting these cards and listening to shortwave radio stations is called D'xing-a hobby.
Now this hobby lost its charm because most of the stations don't rely on listeners feedback to know their reach, due to the advancement in communication technology.
Anyways, you can give it a try.After all this means of communication is the only reliable mode even today.
