Priyom releases Rivet Build 91
02 April 2024
The Priyom team has been working on a new version of Ian Wraith's Rivet decoder for these past months. You probably have used this decoder in the past when decoding modes such as XPA, XPA2 or F06, among others. Today, we are proud to announce that Build 91 has been released!
So what does this new version contain? Keep reading to find out!
F06a decoding
The main change of this update comes with F06 (named FSK200/1000 in Rivet). Due to the increase in F06a usage over the past years, and now running on its own dedicated schedules, the F06a decoder has been split from the existing F06 decoder and is now a selectable mode in the GUI.
As you can see, by default, Rivet will decode the different blocks of a transmission as hexadecimal values instead of the usual digits when using F06a. Keep in mind that F06a carries files, which sometimes are ASCII-encoded and sometimes are just unidentified binary. Rivet b91 provides decoding for both file formats (using binary by default), which can be switched under Options > F06a ASCII parsing.
When using ASCII encoding, Rivet will also print non-printable characters (except CR, LF and EOF) in their hexadecimal values (characters that appear as [0x..]). Line feeds, carrier returns and end-of-file NUL bytes appear as <CR>,<LF> and <EOF> respectively. Apart from this, Rivet will also display the ASCII-encoded filename, big-endian file size and the CRC of the file contents automatically when it detects a header block.
You don't know if what you're decoding is F06 or F06a? No worries! Start decoding as FSK200/1000. Rivet will detect F06a automatically and jump into F06a decoding. And also, if you try to decode a raw binary F06a using ASCII, Rivet will automatically change to binary decoding.
An easy way of identifying the encoding of a file is by reading the filename: Filenames ending with .TLG or .TXT usually feature ASCII encoding, while filenames with no extension beginning with 444 or 044 use raw binary.
Other changes in build 91
