In the osmocom block, I use this as device argument: bladerf=0,biastee=0,agc_mode=manual,agc=0 And this does the trick for me. To change the gain, I change RF Gain (dB) and don't touch...

[TransmitCW.grc.zip](https://github.com/Nuand/bladeRF/files/8379837/TransmitCW.grc.zip) Can you try with this simple example? If you connect Tx1 and Rx1, you should see varying signal strength based on the selected values.

@SameerIrfan I'm sorry that it's not working with you machine/bladeRF. I only have the A4 and A5 and both work fine. I can't help you with the different peaks.
