I've got a Baofeng UV5R. It's pretty good, but to anyone else who bought it with the default antenna, I reccomend a Nagoya 775. Anyone else have a handheld setup?

>tfw my friend dragged me into ham radio few days ago
>tfw its just a bunch of autists talking to each other over radio

I just want to learn how modulation works and make RF electronics from scratch.
Is that such a huge thing to ask :|

I'd say if you're interested in the technology and not the social aspects of ham radio, try a few data modes instead of just voice. Sometimes conversations can be dull.

What books on the topic do you have? I might have a few PDFs I can share.

I've built a couple AM recievers from scratch but now really want to go for something bigger. What should I do next lains?

FSK transceiver and decoder, connected to arduino. Or FM transmitter with SMD components, fitting on a CR battery (a.k.a bug)

I want to be able to use the internet via ham radio while living in my van...

Is this possible? if so, what must I do to make it work effectively and in a power efficient manner?

I've never actually tried this myself.
There are many ways to communicate with other hams using the internet, but the reverse effect could be challenging using the traditional ham bands.

I recently got a BF-F8+. Been playing with it for a while and planning to pass my licence in a few months.
What are the main advantages of the Nagoya over the stock antenna?

SSB receiver? There are a good few simple SDR designs out there too if you want something more modern.
Maybe a beacon of some sort, low powered morse temperature transmitter or foxhunt target.

Not particularly - radio amateurs have an allocation in the 2.4GHz ISM band, but all countries prohibit the use of any encryption by amateurs (WW2 espionage fears + it would prevent the regulators from ensuring that the bands are being used for non-commercial use only). You can do so, but it has to be open and you could never use anything like HTTPS over it.

(another lainon) Pretty simple: it works much better than the included one, though it's also much longer, so it can be a bit clunky.
