Never forget to run Bias-Tee-On batch file!

I’m an idiot!! Just had to discard several weeks of data on my Milky Way Hydrogen-mapping experiment (Ptarmigan array) because I stupidly forgot to run the Bias-Tee-On batch file to turn on power to the software-defined radio dongle!

I think it is working now – graphs from first 16 hours of data collected after running Bias-tee-on below.

But also see this post for alternative solution that I later implemented successfully: https://astronomy.me.uk/replacing-power-from-computer-to-separate-power-supply-for-nooelec-sawbird-h1-lna-on-pharmigan-array-milky-way-hydrogen-mapping-computer
