Transmissions are scheduled to begin on Friday, February 15, at 0845 UTC (3:45AM EST)and run through Sunday, February 17, at 1725 UTC. (12:25pmEST)
SSTV images will be transmitted on 145.80 MHz using SSTV-mode PD120. These can be received using equipment as simple as a 2-meter handheld radio, a scanner that covers that band, or even an online WebSDR receiver. Copying the images is as simple as connecting the receiver’s audio output to the audio input of a computer running free software such as MMSSTV.

See the link for the full text of the article for more information about the issues that happened last weekend that caused them to re-do the SSTV transmissions this weekend.
