Like i said, look into GPT4All. At least for text gen. Open source and really simple. Download, install, choose a model (for mediocre laptops 4-8B ones are a good size) and chat.
For radios, there are some cheap beginner devices as starting point. Look for the rtl-sdr blog v4 usb dongle for about 40€. You can receive ~1-1700mHz with it, which are loads of interesting frequencies. You can buy a 30€ quansheng uv k5 or uv k6 (which is the same model somehow) with custom rom for a great handheld vhf/uhf radio. You can buy a 30€ SI4732 based ATS-Mini as “world receiver” also with custom roms like hjberndt’s.
You could invest some more and get a flipper zero for around 250€ which is a neat tamagochi like IT-Swiss-Army-Knife.
Or a portapack H4M (the new cliffort heath version for the best hackrf one clone) for about 200€. Its the “big brother” of the flipper zero with fascinating capabilities like scanning surrounding ships and planes.
Dont forget proper antennas which can escalate quickly.
But did they say thank you even once??
