To be sure : remove dt-blob.bin in /boot folder
Reboot and set a SR at 250, it should be transmit at 125 KS

OK dt-blob.bin removed now symbol rate is half of what ever is set, ( 250 now 125 ) resulting in a good lock with all green lights in Tutioune but no video display.

Can you record the Transport Stream with tutioune (10-20 seconds) to see what's in ?

I recorded the TS in tutioune but when I try to play the file Windows says the file is un-playable.

Using the PI and Digithin, there is no audio being sent at 333ks. I assume this is intended? Makes sense given the limited bandwidth but just checking.

For now, audio is not included in the stream. Next step !

Does anyone know the secret to switching off the test pattern and returning to the menu? I've tried many keyboard combinations and now admit defeat. :(

Thanks

Thought I'd hit control and every other key; I'll try control a again.

Evariste has done a storming job so I'm happy to wait for the bugs to be ironed out.

Thanks
