RIC 0004520 Encrypted Messages
Posted: Mon May 13, 2019 4:28 pm
I spoke to the one of the DAPNET team about this RIC since the UK is not allowed to use encryption for HAM use, and I was concerned about the encrypted looking messages;
It turns out that RIC 0004520 is a special system RIC that is used for Skyper pagers, these devices need some special data format, its not encrypted, it just looks weird because the character set has to be rotated by 1 character for the Skyper pagers to understand it, so we need to rotate by -1 char.
In order for us humans to read the text, I made a modification to the dashboard to automatically clear the ROT-1 text for that RIC, for added fun I also took a stab at the symbol set that is ALSO being rotated (this is un-usual, normally ROT is only used on text) and that seems to work, but probably needs more testing.
So from the next time you all update, you should now be able to read the (not so exciting) messages going to RIC 0004520.
