Hello, I am working with GNU Radio and I got a problem.

I have seen here: [https://wiki.myriadrf.org/LimeSDR-Mini\_TX\_Gain\_Power](https://wiki.myriadrf.org/LimeSDR-Mini_TX_Gain_Power), that the maximum gain value for the LimeSDR-Mini was 60. But I have used the LimeSDR Sink, and I can use a gain of 0-73, so I don’t know which value is the maximum. Another problem is that I don’t get the same values as in the graphic. For example, with a gain of 30 I get -21 dBm, while in the graphic I am suppose to get around -29 dBm.

Also, is there a block to amplify the TX power?

I hope someone can help.
