By r307 in the previous email I meant r219! (r219+patch = info on console) Just to clarify (more info here <http://wiki.spench.net/wiki/OP25> ): * r307: apply patch to solve the BCH issue now present in the current version of IT++ (i.e. why there's no audio). * r219: apply patch to add DES-OFB decryption and dumping frame info to the console (includes BCH fix). You can try applying the 'r307 patch' to the latest revision of the code and see if it works... I haven't tried this yet.

I've split up the combined 'Decoder' block into the FSK4 and actual decoder (simple) parts. I've also added the traffic pane - you'll see how it fits together in the sample/OP25.grc Make sure you back up your old GRC file before you update so you don't end up in a nasty XML merge conflict! For those people that aren't hearing any audio, check if the traffic pane is showing you anything. For those wondering about talk of patches, instructions are here: http://wiki.spench.net/wiki/OP25 If you use r307+patch, you can also check the console to see if decoder information starts appearing to see if valid frames are being detected.
