Moving on a little bit ...
Ignorance is not bliss, it's an impediment ...
So I've learnt about about the EM spectrum, and the RF part of the EM spectrum.
Next, learning about antennas.
1. Marconi antennas
2. Jansky antennas
3. Reber arrays
4. Dishes and feeds
5. MWA array antennas
At current rate, about 5 years of work, just building understanding as I construct.

List of Radio Astronomy stuff to learn
1. What is electromagnetic radiation?
2. What is the 'radio' part of the spectrum?
3. What is the relationship between wavelength and frequency?
4. How do antennas work?
5. What is the simplest radio antenna can I build?
6. How can I test the antenna and detect AM, FM, CW, SSB on an old multi-band receiver that I have?
7. What types of antennas are used for radio astronomy?
8. Can I fix an old AOR-8000 radio scanner and make it work again even though the 'Scan' button is worn out?
9. What parts of the EM spectrum do radio astronomers work with?
3 x old TV antennas
1 x multi band radio receiver (works)
1 x AOR-8000 radio scanner (doesn't work yet)

One of the basics of 'Land for Wildlife' is fencing off the reserved area and removing non-native animals.
Every now and then the neighbors sheep get in, so today was a 'Removing neighbour's sheep' and
Fixing fences.
Two things of note in this pic.
1. The grass is greener on our side of the fence because only 'Roos graze there, so it's no wonder that the neighbor's sheep are always trying to find a way in.
2. That path down from the tower. Caused by sheep or roos? I'll find out by attaching my motion-detector wildlife camera to that post in the foreground.
