How to transmit 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 Mmsstv?
MMSSTV stands for Makoto Mori (JE3HHT, creator) Slow Scan TV. It has been the defacto standard SSTV application for many years. This is written with the beginner in mind and many concepts outlined step-by-step.
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.
What radio frequency does the ISS use?
145.80 MHz
A ground station contains a device capable of both transmitting and receiving radio waves near the 145 megahertz frequency. The ISS radio transmits signals at 145.80 MHz and receives signals at either 144.49 or 145.20 MHz, depending on its orbital location.
What frequency is the ISS on?
Is ISS transmitting SSTV?
Transmissions from the ISS will be on 145.800MHz FM using PD120 SSTV mode. The SSTV images will be transmitted continuously. Transmissions will start at or about 0940UTC on the 21st and will end by 1830UTC on the 26th. Signals should be receivable on a handheld with a quarter-wave whip antenna.
How wide is an SSTV signal?
A literal term for SSTV is narrowband television. Analog broadcast television requires at least 6 MHz wide channels, because it transmits 25 or 30 picture frames per second (in the NTSC, PAL or SECAM color systems), but SSTV usually only takes up to a maximum of 3 kHz of bandwidth.
What frequency do astronauts use?
As mentioned above, the transceiver on board the ISS is tuned to transmit radio signals at a frequency of 145.80 MHz. “Anybody with a receiver or scanner able to tune into that frequency can listen to the space station when it’s overhead,” Ransom said.
How are the tone frequencies defined in MMSSTV?
For info on what each one does click here. (1) Tone frequency SSTV’s tone frequencies are defined as follows: Synchronization pulse 1200 Hz Low level of the image 1500 Hz High level of the image 2300 Hz There are four marker lines in the spectrum window of MMSSTV.
What is the freq frequency for SSTV radio?
