Sorry to bump an old thread, with a new post.
I couldn't find this in the prop manual, or the hydra book.
so reading this post/discussion.
I know this is talking about FM mod. but my understanding is the ctrB gets AM modulated by ctrA, if I said this right, in the tv driver.
The datasheet says the broadcast carrier frequency is generated by ctrb, I just followed the datasheet.
Got it. One of the less often referred to (by me) parts of the documentation :)
so I guess it is in the "propeller datasheet" pdf from the prop tool.
yeah, got an rtl-sdr and yup its all over the place.(cog modulation of video on channel 2 or 3)
Now instead of barewire antenna, if you put it on coax directly into the tv antenna, would that shield all that junk going out on the air?
I got a few cheap b&w crts, but they don't have rca jacks. so I have no way to get the ntsc into them.
I haven't looked into hacks to add an rca jack to them after the ntsc gets demodulated off of the channel frequency, if that's how to say it. Is it safe if done via coax with no antenna?
