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.

Hello Adrian,
The USB interface is integrated in the RTL-SDR chip (RTL2832U), so it cannot be
replaced (as far as I know).
In theory, USB 2.0 can support faster data rates (HackRF does 16 MS/s - 20 MS/s
with USB 2.0 8 bit I-Q). As Ron mentioned, it is due to the cost reduction.

Hi Kyeong,
Thanks for all the answers!

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
I tried to listen to the NTSC channel audio using a FM receiver I made, and I
got it, I could listen to it perfectly.
That should be a good way to prove that I'm receiving the channel signal, for
that reason, I don't understand why I just receive a diffuse mix of black,
white and gray image ins
