Hi Andres,
just had a short look: doesn't NTSC use a nearly 6 MHz bandwidth?
Best regards,

Yes, no way with the RTL to catch NTSC, it does in SDR mode only

First, I will talk about the things I know for sure. The
NTSC analog system as well as Pal systems in a lot of the rest of
the world had a lot in common with eachother. Both systems
transmitted an AM video signal in Vestigial single sideband mode
such that the carrier frequency was always
Hi Martin,
internally, the RTL dongles are fast enough to capture full DVB-T (not
-T2) channels, and demodulate, and decode them, and deliver the video
stream to the host. However, RTL-SDR can't use that mode - it uses a
"bypass the whole Digital TV specific stuff" mode and directly passes
IQ samp
Hi Marcus,
You're right about the RTL sample rate, but I'm curious about why it is so
small.
Is it the bus speed? The ADC is obviously fast enough for DVB-T2.

The maximum Transport Stream rate of DVB-T is 31.67 Mbps, so the USB
interface only needs to deliver 4 MB/s. Since you need two 8-bit samples
in IQ mode, it's 2 Msps.

Hi Ron,
So in theory, replacing the USB2 chip with a USB3 would allow access to the
full sample rate, or is there some other internal limitation?

It's all about making them as inexpensive as possible. The USB
controller has just enough bandwidth for the intended purpose. On a
consumer product, even a few cents makes a difference.

I must think a little better next time. I looked at my
posting to the list and realized I was being rather dim-witted in
that I was imagining the signal path for the video as needing the
sound card as it does when one is decoding the sound carrier or
an FM radio station. In theory, one co
