SINPO, SINFO, SIO, SINPFEMO, and RAISO codes
Posted on February 21, 2014
The good ole ‘Arcane Radio Trivia’ blog presents another bit of obscure trivia.. Never heard of these broadcasting acronyms, but found it interesting
The current blog (Feb. 19, 2014) talks about SINPO and SINPFEMO Codes, and some others You can read his blog at www.tenwatts.blogspot.com detailing what the rest of each one of them mean; but here are the key hightlights to wet your appitite on reading the entire blog yourself…

SINPO and SINPFEMO Code -http://tenwatts.blogspot.com
SINPO is an acronym. Here’s what it stands for:
- S – Signal Stregnth
- I – Interference
- N – Noise
- P – Propagation
- O – Overall Rating
In shortwave radio, a SINPO response indicates to the transmitting station the quality of the received signal.
..references the same code as “SINFO.” In that case, the ‘F’ stands for Fading, instead of ‘P’ for Propagation. They are otherwise identical. There are also scant references to an SIO code…
This has diminished over time and the SINPO scores have become less formal. This may have led to the creation of SINPFEMO..
- S – Signal Stregnth
- I – Interference
- N – Noise
- P – Propagation
- F – Fading of Frequency
- E – Modulation Quality (Excellent)
- M – Modulation Depth (Maximum)
- O – Overall Rating
It is highly likely that both systems originate in a much older code created by BBC engineers called RAISO….
SINPO and SINPFEMO were formally recommended.. in 1961.
