Re: [Flexradio] Receiver sensitivity was "deaf receiver"
I had a situation in my early SDR where the diode protection across the preamp was not present. I managed to blow out the preamp from a strong RF field in my multi transmitter station. My RX was deaf to say the least. The fix was easy put in a new amp and add the diodes. So check to see if the diode protection is present. My other SDR had the diodes and exposure to similar RF fields has caused no problem 73 W9OY Yahoo!

Re: [Flexradio] Receiver sensitivity was "deaf receiver"
Ross, It should be -107 dBm. Mine fluctuates around -107 to -108.
