Hello Again, I think i know the answer to this question but I still hope i am not right.
Setup N210 with SBX One of my colleagues plugged in TX/RX an external discone antenna with an RG58 cable playing around in the 3 Ghz band. Somehow he managed to get down to 400 Mhz where db increases partly because of the antenna gain and the reduced attenuation of the cable. After some experimentation the SBX stopped receiving signals. I changed antenas (LP0965) cables etc removed and reinstalled the SBX but it wont give me any signals. Usrp appears to work alright - leds flashing etc but i dont have another daughterboard to test it. SBX is flashing as well but no signal in TX/RX nor RX2. When tuning different frequencies there are no errors etc, but i receive just noise. I think that the down left corner of the SBX (as you see it- to the left of RX2) is getting hotter than it used to. That leads to the question, is the Db dead? Any way to fix it? Is there a limit in the input db when connecting an external antenna? I would guess an attenuator would be needed? Thanks alot, R.I.P SBX Jason -- View this message in context: http://old.nabble.com/SBX-Daughterboard-dead--tp33432423p33432423.html Sent from the GnuRadio mailing list archive at Nabble.com. _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
