SSTV is a form of encoding allowing You to transmit pictures over virtually any transmission medium that allow uncompressed human speech – starting from phone ending on SSB radios. It’s similar to “fax” that was used over landline.
For testing i decided to record couple of SSTV sample audio files using different encoding to compare quality.
The slower (longer time) works better on noisy frequency like SSB.
Quicker one working perfect over AM/ FM.
Here are files for testing, You can decode them from “speaker” using Android smartphone and application called “Robot32” <- don’t let name mislead You, it decode all modes used here!
Teardown to see what’s inside:
This is good real capacity battery.
When i was making jumper connectors to set up SignaLink i decide to take couple pictures and show You what’s inside.
Quick testing of RadioTone RT5 Zello PTT mobile radio (it’s dedicated to use in car but in mine application will be a base station).
First impression is good, very loud and clear audio , remind me very much DMR Motorola DM4600 especial round mic connector plug… and i like it 🙂
Keep in mind this is not a DMR radio, just android smartphone.
Video and Pictures 🙂
Couple pictures of tear down TRI PRC 152 and check if possible to replace audio accessory connector with real one.
Description says it will fit DP3600 but how about reality?
