How do I use Sstv?
All you need to do to receive SSTV pictures direct from the space station is to connect the audio output of a scanner or amateur radio transceiver via a simple interface to the soundcard on a Windows PC or an Apple iOS device, and tune in to 145.800 MHz FM.
What is the repeater offset for 2 meters?
Standard 2-Meter Amateur Radio Repeater Input Frequency Offsets
| 2-Meter Repeater Output Frequency | Standard Input Frequency Offset |
|---|---|
| 146.0 MHz – 146.4 MHz | +600 kHz |
| 146.6 MHz – 147.0 MHz | -600 kHz |
| 147.0 MHz – 147.4 MHz | +600 kHz |

What is the fastest SSTV mode?
The fastest mode of the Robot family and the fastest color SSTV mode is the 12s mode. It contains 120 lines transmitted in the 4:2:0 format. Another mode is 24s with a 256×120 resolution and 4:2:2 color format.
Is SSTV a digital mode?
Digital SSTV is a recent innovation whereby multi-carrier Orthogonal Frequency Division Multiplexing (OFDM) techniques, based loosely around the Digital Radio Mondiale (DRM) broadcasting protocols as used for commercial Digital Radio Transmissions in Australia, are used to digitally encode and broadcast images and …
What is SSTV image decoder?
Slow-scan television (SSTV) is a picture transmission method, used mainly by amateur radio operators, to transmit and receive static pictures via radio in monochrome or color. Since SSTV systems operate on voice frequencies, amateurs use it on shortwave (also known as HF by amateur radio operators), VHF and UHF radio.
What is offset on a repeater?
The difference between the repeater’s receive frequency and its transmit frequency is called the offset. Let’s call the frequency that the repeater transmits the Output Frequency. Let’s call the frequency the repeater receives the Input Frequency.
What is the freq frequency for SSTV radio?
223.850 MHz 1.25m Band SSTV Call Freq. 2 metres: (FM) 145.500 MHz 2m Band SSTV Call Freq. 145.600 MHz 2m Band SSTV Call Freq.
What kind of signal does SSTV have?
Ok on with the show. An SSTV signal consists of a constant amplitude audio tone, varying only in frequency. A very basic explanation of how it works is that high tones are for bright areas and low tones are for dark areas. To explain any further is beyond the scope of this primer and also taxes the knowledge of the author.
Which is the 80m band of SSTV?
80 metres: (LSB) 3845 kHz 80m Band SSTV Call Freq. 3730 kHz Europe Call Freq. 3733 kHz Europe DIGITAL SSTV Call Freq.
Do you have to use high power for SSTV?
The duty cycle of the SSTV signal will make short work of your final stages. Cut back to medium or even low power if the rig has this capability and you can still hit the repeater. If you must use high power, give the rig a good rest between picture transmissions.
