[Discuss-gnuradio] spectrum record

Hi Marcus, list,

Thanks for swift response.

You are right about openBTS, but at the same time I am using really old system (12.04) havent formatted for years due to its required installation, which can turn into real time consuming tasks thats why dragging it as long as I can avoid above situation.

Now Decimation, yes its seems right to me as well, but when I am trying to decode I am getting SCH errors (I am using channelizer.py given in GR example directory for this purpose) with following configuration

channels= 10

sample rate= clock rate/decimation

pfb decimation= 4

OSR= channels/pfb decimation= 2.5

but when I am recording single frequency with 156 decimation, it works just fine.

partially I believe this question belongs to airprobe mailing list, but think there is very little or null development on it, thus thought to coin it here, a much active list.

I want to make sure I am not doing anything wrong in spectrum recording and channelizing afterwards once it comes to airprobe, will give a head on

Also if libusrp is the only bottelneck for me, I will change my system configuration and install GR-3.6 (which I think supports openBTS and UHD as well)

at moment I am moving like headless chicken between GR and airprobe, not sure who is and what is going wrong, please spread some light here.

Thankyou
