P System for SSTV Signal Reporting

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.

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.

SSTV Cams on 30m-Narrow Band

Op Gary; Neenah, WI

Op Larry; Appleton, WI

Here are operating tips for operating Narrow SSTV in North America.

  • The calling frequency is 10.132 MHz USB.
  • You MUST use a narrow transmission mode. If you have doubts, please read this research paper.
  • MP110-N is a good SSTV modulation mode.
  • 30m is only 50 kHz wide. We share with digital ham modes and other services. Listen before you Tx.
  • Based on a 10-month study, it is now suggested hams try to call in the 2200 UTC time slot.
  • Encode your FSKID in MMSSTV TX configuration to better identify any weak signal.
  • The PLL demodulating method seems to work best for picture Rx.


SSTV Cam on 40m Band


Op Brad; Salida, CA


Op Larry; Appleton, WI

Occasionally I set my 40m ICOM 7200 on 7.171 MHz LSB to monitor for infrequent SSTV transmissions. If I am monitoring, you will see my copy here.

10 meter Beacon & Simplex Repeater

I have a beacon at 28.680 MHz that transmits about every 30 minutes. In addition, if band conditions are favorable, you may activate the station for a SSTV transmission. Follow these simple steps:

  1. Transmit a 1,750 Hz tone for 1 1/2 seconds. You will find this TX tone button in the TX section of MMSSTV.
  2. Wait for WA9TT to transmit a CW identification.
  3. Pause for a moment, then transmit your picture.

If my station adequately receives, I will re-transmit that received picture in the same mode that you sent it. I run 50 watts into a PAR Electronics Rectangle at 18 feet for an omni-directional beacon.

Here are the most recent transmission received by me and other 10 meter SSTV beacons. We operate with a coordinated repeater access tone band plan as indicated under each call sign. I thank Terry N3YHW for his artwork which depicts our beacon community!

Amateur Slow Scan Television (SSTV)

SSTV 20m 14.230 MHz

Narrow SSTV


Ham Nation Feature on SSTV

I was asked by Ham Nation to produce a short video about Slow Scan TV. This appeared in the 113th episode.

MMSSTV for Beginners

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.

That Pesky Slant

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.

One small step for man, one giant leap for mankind

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.

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.

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. I suggest you look him up on as you will discover many brilliant things Gary has accomplished in his career.
