ATSC 1.0 transmit errors

Hello

 I am using GNU radio companion 3.10.12.0, python 3.12.9.

I installed the windows version on a windows 10 computer.

 

I implemented the ATSC transmitter example from wikipedia.

I have three errors. They are all links between blocks and I have no

idea why they are erroring.

 

The first is the link path between the FILE SOURCE block and the ATSC PAD.

 

The second is the link path between ATSC FIELD SYNC MUX block and 

the VECTOR TO STREAM.

 

The third is the link path between KEEP M IN N block and DVB-S2X MODULATOR.

 

I am using adv16apsk910.ts as the file source.

I hope someone has the answer for me.

Mike
