Mail Call: Postcards Aplenty & If a Picture is Worth a Thousand Words, How Many Minutes of Audio is it Worth?

One from Correspondent Gunier K, relating yet another adventure in Paradise. One from Correspondent Kristy T, who teases a mysterious letter arriving soon.

And, while I recently told Tape Pal Mitchell F. that I had no ideas for the next Tape Pals 3-Way Round 5, I have since come up with one. Here’s a test of the concept: Well, that’s the result from the digital generator – but I record it on the PMD430, and the motor speed issue I noticed before seems to corrupt the data stream:

  1. Good to know my postcard made it, I was a bit worried it got lost in the post! First time writing a postcard, I think the only mistake I made was forgetting the date…
    Your kidding; I’m planning on using Slow-Scan TV in our Tape Pals 3-Way! That makes things so much easier, You obviously must already know how to use the software!

  2. Well, I have no idea for this round of Tape Pals, as I sit on the package and await the Muse! So, what’s your idea? Pets? Hmm…

    1. Gunier got it, it’s a technique used by NASA and HAMs for transmitting images over shortwave – still testing, though – the result is distorted by the subtle tape motor speed slowness on my PMD430. I’ll have to try my PMD201 to see if it’s more stable.

      But also yes, pets. (:

      1. What software are you using? I personally use a program called “MMSSTV”; That one has features & SSTV standards aplenty, as well as automatic image sync correction.

        1. for encoding:

          and then for decoding, I have Robot36 on an android pad.

          Still can’t get it to work right on tape. May not be able to make it work given the variety of speed issues on 30-40 year old tape decks.

          1. I think it’s just the image stabilization that’s your problem. When I was figuring out the software for the first time, my images from tape came out looking similar to yours. Only after I toggled a setting, something like “Auto Image Stabilization”, did I get good results. I hope this helps!
