[USRP-users] The signal received by B205mini is unstable

2022-10-25 Thread luteo
When testing the B205mini, we found that the SMA connector was tightened to the most tight, but there may be no signal or the signal is weak. Of course not always. Sometimes it is better to loosen the SMA connector a little. In short, the reception effect requires repeated adjustment of t

Hello Brian, Thank you for the additional information. Regarding #6, I meant that if you have two TwinRX daughterboards, see if you get this problem when the fixed channel is on one daughterboard, and the tuned channel is on the other. Regarding screenshots, are you referring to any particular

Hello Brian, I'll see if I can reproduce with my TwinRX. Please provide some more information to help me reproduce... 1. Center Frequency of fixed channel 0 2. Tuning range on channel 1 3. What tuning rate have you tried and what's the threshold between a clean spectrum and a bad one? 4. Please

Hi Jorge, hope you don't mind me replying on the list itself - as this is really just the same email as before :) So, yes, you'll need one of gmp or mpir. But these should be there, since you already seem to have built GNU Radio for the ARM target, right? That's what's confusing me. Best r
