"Hi as many others here I did something wrong when I Transmitted with my HackRF and I've discovered that it produced very little power when i've activated TX Amp (if TX Amp is off the signal is normal)

So i am suspecting that i've destroyed TX Amp"

I spent two days trying to transmit with my HackRF using 
HackRF_Transfer on Windows.  I eventually discovered that there 
is only tiny distorted output with RF amp set to "1". With it to
zero it works as expected. This was frustrating as its clearly 
documented to work! 

Attempting to use SDR# to receive causes the RF amp to work correctly. 

I seem to recall the amp working on transmit using GnuRadioCompanion
on Ubuntu, but now that I've got the thing working on a non-niche OS
I'm not going to try that again! 

Could it be a software bug or bad documentation?
