Hi D J,
Thanks for the link, this is alias. If I fix the waveform frequency, say
2.4e6, and increase tx sampling rate from 5e6 to 10e6, this problem should
be solved right? I just did experiment, and found the second component
disappeared.
Thanks,
Yang

Hi Jeff,
I tried to reduced the gain and the second component became weaker, but it
is always there. If this is alias, I am wondering if I choose the wrong tx
sampling rate. In this case, the sine wave frequency = 2.4e6, current tx
sampling rate = 5e6. I tried to increase sampling rate from 5e6 to
For some times oot modules are sorted into a subtree (no module
specified ). On 'mouse over' the developers are asked to update their
xml - files with module names.
If I look into the gnuradio xml files the module name always seems to be
[core].
Are there recommendations for oot- modules or
Are you using gr_modtool makexml command. Sometimes its not very much
helpful(it also says so). I always take any example xml from the existing
libraries and then paste my stuff over them.

I want to access multiple USRPs from a host for MIMO. Currently, I need
change IP address of host (subnet) to be able to access each USRP.

- Ethernet interface IPv4 address: *192.168.10.1*

The default in gr_modtool is to create a category with the module name.
For example, gr-whatevs would end up in the "whatevs" category. However,
since it's common to capitalize categories, it should probably be
changed to "Whatevs".
I just pushed a commit to gr-paint to use the category "Paint

Hi,
I have the following function:
float blk::func(uint16_t *argmax, gr_complex *vector, uint32_t vlen) {
cout << "0: " << vector[0] << " (" << abs(vector[0])<< ")"
<< " 996: " << vector[996] << " (" << abs(vector[996]) << ") "
<< " 999: " << vector[999] << " (" << abs(vector
