Hi, I am new to limeSDR and I am having trouble with getting reasonable power outputs when controlling the lime with both LimeSuite and GNUradio Companion code. For LimeSuite I am getting a spike that peaks at -30dBm at 435MHz.

When using GNUradio I briefly can see the waveform that I would expect and then it goes to almost non-existent spike at like -60dB. I have tried very basic examples such as a signal source to the gr-limesdr Tx block and still get these results. Looking for any help and advice.
