| I recall a project that allowed you to tune into long radio
| emissions from the sun -- perhaps keep tabs on the solar weather?

| Nifty to see this. I was recently brainstorming about FOSS

| working out minimum requirements for targeting adversary
| satellites. A lot of budget-constrained forces might be able to
| leverage SkyRoof to fill this gap.

| Source code is here: https://github.com/VE3NEA/SkyRoof

| It's in .NET so I'd think it ought to be buildable on Linux too?
| Unless there are some specific hardware/driver requirements
| involved (there isn't much in the readme right now)

| Thanks for the link!
