In late November 2016 I became a licensed amateur radio operator. The reason I got the license was to learn more about the black magic behind radios; antennas, radio waves, frequencies, bandwidths. How to transmit, how to receive, what to do and not. Being able to play around on the air, legally, is a huge bonus. I've learned a metric tonne about stuff I hardly knew anything about.
My official callsign is LB5SH (have fun keying that one), but I still don't have much radio equipment to play with, other than a handheld 8W Baofeng GT-3TP. It's good enough to get in touch with the nearby repeaters.
I have ordered a 100W amplifier kit and will soon buy an X-50 Diamond high-gain low-WAF antenna to put on my roof. With a little luck I'll be able to play without the use of repeaters soon. I'm damned to 2m and 70cm bands, since HF is pretty much a no-go due to the physical limitations where I live.
Anyway, why am I telling you this? Well, yesterday I transferred my first homemade data packet on the air. To me that was an adrenaline kick. It didn't do much, it wasn't useful, but it worked, and that was a milestone. An APRS (Automatic Packet Reporting System) packet was generated in software on my PC, sent via the radio, via two local digipeaters and then eventually ended up on aprs.fi. This was a test to make sure that my "synthetic" waveforms were A-OK, so I can render something similar on a microcontroller later.
Now to port the code to an AVR or something and see if that works...
