[Hackrf-dev] Is my new (old) HackRF Deaf?

[Andrew Rich]

With my hack rf I have three sliders

Rf gain
Lna gain
VGA gain

If you set one of these to like a 1 it goes deaf

It varies between programs too

Some have base band gain 

I can make mine deaf

Tonight I found one station… with or without  averaging set and using the default flowchart in Mike’s website tutorial – background is about -80 dB and I can finally see and see some FM signals.  With 10MHz span (95-105 MHz) I see a wide broad signal extending from about 98.5 to 101.5 MHz with some signal spikes riding on top to about -55dB.

> Is my HackRF deaf?  I am a ham radio hobbyist and I bought a HackRF One to enhance my deeper learning of SDR but also as a broadband RF source.  To my dismay, installing the software has become days of learning Ubuntu basics and dealing with instructions that are at times outdated or nuanced towards a person with much more than basic Linux skills.  So, I gave up on Ubuntu only because it was faster for me to install and test with Windows 7.   My HackRF One (GreatScott) must have been a leftover as the firmware was dated 2014(August).  I installed the latest version HackRF tools and updated the firmware to Feb 2017.  I followed Mike's video tutorial for creating a basic GNU flow for FM and also installed SDR#.  I have very strong FM broadcast stations in my area which I can easily demodulate with my Rigol Spectrum analyzer using the ANT500. However both with GNU and SDR# my HackRF appears deaf in FM broadcast mode.  I read that a few years back there may have been some issues with cold solder joints on the HackRF pcb....  I have a lot of test equipment - from RF generators up to 2 GHz, etc but before I go that route is there something I am perhaps missing in my setup.  Not sure where or what details to provide here without overloading my question further
