Not actually, not possible. I tested today. It does not receive anything.

Yes, it's possible. The use of the rational re-sampler
is to be compatible with commercial DVB-T receivers.
If you're just interested in USRP to USRP, then it's
okay to use a 10 Msps sample rate. The signal will
be slightly wider than a standard 8 MHz signal at
9.142857 Msps.
You can modify my DV
Can I trans/receive without Rational Resampler?
It distorts the signal too much :(

Thanks a lot! I will try them too...

One thing I did once and worked are:
1. Use a file sink instead of USRP when transmitting. Then, once the file is
generated send the samples from file (opened in a file source) directly to
USRP. That will need a good harddrive with at least 80MB/s read speed, a SSD
will work probably.
2. Do

I'm afraid you can't reduce needed sample rate for a fixed bandwidth.
You need a stronger laptop. Often, plugging it into mains power helps.

ohhh, now I understand.
It produces in the transmitter side - which probably means underflow with
my laptop.
Do you know how to decrease this power?

For dvbt the bandwidth is around 9.14Msps so with the rational resampler you
need to set-up the USRP at 10Msps. 1Msps will not work as only a part of the
spectrum will be received.

Hi,
Thanks!
I am using collected data also as you say.
I am using sampling rate of 1 Mbps instead of 10 Mbps which must be the same
for static transmission. Isn't it?

Hi, not having access to my setup for now but for the beginning you could try
recording the spectrum with your USRP and then use the file source to decode
the signal offline. There is a script file apps/capture.sh that I usually use
to capture data. You may tweak it for your needs (frequency, ga
