What is Reddit's opinion of SSTV Encoder?

From 3.5 billion Reddit comments

Yes, it is FM on 144.50. I did arrange the QSO with my pal beforehand. The way we did it (and not sure if it's the standard way of going about this, but we're trying to do what we feel is best practice) is to initiate the session like a regular phone QSO to identify ourselves and make sure our equipment is up and running for the decoding.

Being simplex 2m I figure if we're not 100% perfect on how we're doing this at least the unintended consequences would be minimal. Maybe 70cm would be a better choice in that case? I'm not sure about just transmitting: hopefully somebody with some experience will clear that up, because I'd love to know as well!

I'm only a tech, and most of the SSTV action is on HF, so we're kind of figuring this out as we go along. That being said, I'd probably benefit from doing more research, but when the experimentation bug bites I tend to dive in head first!!

I use Robot 36 and SSTV Encoder (https://play.google.com/store/apps/details?id=om.sstvencoder&hl=en_US) to do the heavy lifting, and they work a charm! The default settings work right out of the box, as I didn't have to change a thing to get up and running.

Think of when you picked up the phone when you had a dialup modem dialed out to ISP. It uses audible sound frequencies to generate a modulated tone.

If you have Android phones, you can experiment without radios, just a single phone.

Can use: https://play.google.com/store/apps/details?id=om.sstvencoder to encode images to sound and; https://play.google.com/store/apps/details?id=xdsopl.robot36 to decode them. Use the first one to encode your image and run Robot36 to decode at the same time.

Mine does not show b&w anything

The SSTV image is indeed real. The person in that video is encoding it using the "Scottie 1" mode. /u/Sourec decoded it for you, and you can see the decoded image cuts off right as the video's audio cuts off at 1:22.

If you're interested in this sort of thing, ham radio operators often use SSTV to send pictures across the world over radio systems originally designed for voice. You can download the MMSSTV program to generate your own or find dozens of example transmissions on youtube. There are also android apps for sending and receiving the images over speaker audio, and I'm sure similar apps exist for iOS.

There is a version of fldigi for android called AndFlmsg. It can do a lot of different digital modes, although not as many as the PC version.

There is also SSTV Encoder and Robot 36 for sending and receiving SSTV images.

With the SSTV Encoder app

this is probably far from the best solution but this https://play.google.com/store/apps/details?id=om.sstvencoder is ok

heres the encoder version https://play.google.com/store/apps/details?id=om.sstvencoder
