Perhaps this might not be the right forum, but if not I figured someone could guide me to the right place.
I'm running GQRX 2.61 on Ubuntu 14.04 with a NooElec r820T2 SDR NESDR Mini2 Dongle through a NooElec HamItUp . When I run the HamItUp in passthrough, everything works fine, I get local stations where I expect them, repeaters where I expect them, I call into the repeaters, I can hear it on GQRX.
When I run the HamItUp on upconvert, I get no sound. I have verified that this is a +125 model, I'm a math teacher so I'm pretty sure I'm doing the addition right.
I need some guidance on setting this up properly to work with GQRX or verifying that it's a bad unit.
