Use this as a guide to video quality rating, based on a P scale, instead of the less descriptive RSV report. Read about SSTV Reports Using the P Scale in a feature article from CQ magazine. For an in depth discussion, read Image Quality.
How to Modify MMSSTV for P-signal Reporting
P5: Broadcast quality |
P4: Good, some noise |
P3: Usable, noisy |
P2: Barely use, noisy |
P1: Barely see text |
P0: Unusable |
Here is an example of how hams can clearly, cleanly, quickly communicate P-scale signal reports which are easy to visualize by the sender.
3B8FA copies me P4 from 10,000 miles away |
WA9TT Rx of Pat's P3 sig |
3B8FA gets my signal report reply |
KAØCSL, however, copies P5 |
Here are SSTV cams in North America which TEND to receive the same transmissions as I do at WA9TT.

The SSTV community of hams fondly remembers our passing brother in the hobby, Terry Cooling EA3EWO SK July, 2019. Terry was first licensed in England in 1984. In the beginning, he was active with microwave, up to the 10 GHz band. He was in the Grenadier Guards 2nd Battalion from 1966 to 1973. His claim to fame was being in Princess Anns bedroom, riding on Prince Charles' Go-kart & knocking off angels from the main gates of Buckingham Palace with his Army truck! Terry and his wife, Sandra, spent many years in Spain before and during retirement. During this time Terry devoted 90% of his ham radio passion to Slow Scan TV. God bless. |

Here are operating tips for operating Narrow SSTV in North America.
|
There is a wonderful fraternity of hams operating SSTV. You will find many stations on 14.230 MHz, a frequency I often visit. This guide endeavors to provide ideas, hints and tips for the new SSTV operator: to help get you started quickly to enjoy this fascinating area of amateur radio. |
Copying a station with slant can be difficult, if not impossible. The station on the left has a transmission slant of -4.16 Hz. The station on the right is unintelligible with a slant of -25.92 Hz. This can be fixed with the aid of a guide which you are welcome to download. I offer two alternative approaches.

These tutorials are designed to help hams make the greatest use of their MMSSTV software.
Slow Scan TV was developed a decade before by a young ham, Cop Macdonald WA2BCW (now VY2CM), while attending the University of Kentucky. SSTV was used to transmit the black & white image of Armstrong stepping onto the lunar surface.
I am pleased to become a member of the World Slow Scan TV Club 44 years to the day of that historic lunar landing. My member number is 325, awarded July 20, 2013.
Later in the evening, to commemorate the 1st hour of Armstrong's lunar walk, I worked WA4DXP via PSK31 on 20 meters at 0204 UTC on July 21, who operated a special event station from the Rocket City of Huntsville, AL celebrating the 44th anniversary of the Apollo 11 Moon Landing.
Here is my QSL card from WA4DXP for this special event.
Apollo 11 landed the first humans, Americans Neil Armstrong and Buzz Aldrin, on the moon on July 20, 1969. Armstrong was the first to step onto the lunar surface six hours later on July 21 at 02:56 UTC.
Armstrong spent 2 1/2 hours outside the spacecraft. Aldrin slightly less. Together they collected 47 1/2 pounds of lunar material.
A third member of the mission, Michael Collins, piloted the command spacecraft alone in lunar orbit until Armstrong and Aldrin returned to it a day later for the trip back to Earth.
Now just where did that historic saying originate? It is reported to have been suggested by a British space tracking technican on assignment at Tinbidbilla Tracking Station
in Australia. Just hours before the NASA launch, he offered this to his supervisor. His most refined version was "One small step for a man, one giant leap for mankind."
I met Gary G7SLL through an SSTV QSO on 20 meters. This is where I learned of his fascinating career and this account. Gary accomplished many brilliant things throughout his career. He passed away on December 16, 2019. He will be greatly missed. |
