How to report an ATV signal
Picture Quality
The series of images with increased levels of "snow" are a rough guide to what ATVers would refer to as P0 to P5.
|
ATV users may have a poorer quality than the repeater as their signal into VK3RTV may be weak. |

 |
 |
 |
| P0 very poor signal. | P1 more picture than snow. | P2 detail in picture. |
| Every ATVer attempts to achieve a "P5" picture with "Q5" audio. | ||
 |
 |
 |
| P3 more detail than snow. | P4 great detail, bit of snow. | P5 perfect picture. |
Audio Quality
Sound / Audio is measured in a similar way to picture except the "snow" is heard as "shussss" or "hisssss".
Lots of "shussss" or "hisssss" which is referred to as noise is a Q0, up to no noise being a "Q5".
"Q" is used here to identify the "quietness" of the audio signal.
This series of 3 second wave files (~23KB each) with decreased levels of "noise" are a rough guide for Q0 to Q5.
| Q0 wave Very Noisy, hint of Audio |
Q1 wave Audio is above Noise |
Q2 wave more Audio than Noise. |
Q3 wave ~50 audio / ~50 noise |
Q4 wave A little bit of Noise |
Q5 wave Very quite no Noise. |
