3 mW ionogram

I've been playing with my low cost, low power, low footprint ionosonde. I'm still missing some parts for the system, but I thought I'd give it a try. Here is an ionogram using 3 mW of power fed into a badly mismatched antenna.

Hopefully very soon in the near future, I will have the prototype ready, and I can convince somebody to fund a large network of these things.
