Re: KerberosSDR 1.6.1 update rate issue

That problem is related to power problems. I recommend trying shorter USB cables. I use 12 inch (30 cm) USB cables and never have problems. People tend to say "I'm using a 3A power supply!", but that doesn't matter if your cable is too long and not the greatest quality.

Re: Tablet for SDR

I've used a Surface Pro 2 (circa 2015) for rtl-sdr applications, and it's really worked well. I don't foresee any problems with the newer surface tablets, especially if you stick to an i5 or better processor.

Lastly, we have our electrical team looking into a lightweight diy rf switch so that we can change settings and handle calibrations on the fly should the need arise.

Re: Need Some Help in Specific 121.5 Mhz Application

hydra_receiver.py and hydra_signal_processor.py along with the C files you havr to compile the first time you pull the source code are really the core components of the program. hydra_main_window.py is sort of the glue that holds it all together and is what hosts the GUI.

I'm glad that helped. 16.04 is going end of life this year anyway, so it's best to upgrade.

Re: API

Stripping the GUI out of the program is an absolute mightmare of a task that basically involves rewriting the whole thing. Supposedly there's a new version of the software being released soon. I've wanted to take on the task of making a GUIless version, but I'm holding off on that until I see what t...

Re: Window not showing - pyqt4 errors on ubuntu 16.04

So you're saying

Code: Select all

sudo apt install python3-pyqt4 pyqt4-dev-tools

Any reason not to upgrade to Ubuntu 18.04?
