Re: Issue with USRP N210

Hi

Possible mistake:

• verify the antenna is connected to the selected Rx port
• verify the antenna really have some gain in this low frequecy range (I had this issue with low cost 900 and 1800 Mhz anennas which are less efficent than a 20 cm single wire directly connected to the Rx port)

Dear,

I'm starting with USRP N210/Gnuradio, so my first exercise was to test it using uhd_fft. Here is the result I'm getting:

uhd_fft --args "addr=192.168.10.2" -A RX2 -s 10e6 -g 10 -f 102e6

It seems to be that the result is not really as expected. In this FM band, I should see plenty of spikes which is not the case. Also, for the one that exists (100Mhz), the power is at -70dB which also seems too little to me. FYI, I'm using the clocktamer 1.2. I appreciate your support to make sure I have everything properly setup.
