HKL's Notes (szo.cc) appears, based on the extracted article content, to be a personal technical blog with the subtitle “Just record things.” Rather than a commercial SaaS product or resource site, it is a long-running collection of the author’s notes on networking, systems, radio, and development practices. The author’s location is listed as Guangzhou, China, and the site provides LinkedIn, email, and a PGP public key.
The site’s core function is publishing and archiving articles. Recent posts cover topics such as flashing and calibrating an MMDVM Hotspot, migrating from Quagga ripd to BIRD2, automatically building MMDVMHost/DMRGateway with GitHub Action, running related components on Windows, Zig cross-compilation, converting GSM calls to SIP with a 3G Modem + Asterisk setup on OpenWrt, and installing Alpine. Overall, the content leans toward network engineering, amateur radio digital repeaters, Linux/OpenWrt, and troubleshooting low-level development environments.
No membership plans, paid downloads, advertising packages, or consulting rates appear in the extracted content, so it can be considered free to read publicly. The commenting options are also fairly simple: via email or GitHub comments.
The main advantage is that the content is highly practical. Many topics cover niche issues that are not widely documented on the Chinese internet, such as hands-on combinations involving MMDVM, DMR, BIRD2, Asterisk, and OpenWrt. The blog has also been updated over a long period, making it valuable reference material for engineers facing similar problems. The downside is that, like many personal blogs, it lacks a structured course-like format. The extracted content did not show supporting features such as search, tags, a table of contents, or RSS. Readers will also need to verify for themselves whether each article is complete and whether the commands apply to their own environment.
It is suitable for network engineers, Linux/OpenWrt enthusiasts, amateur radio and digital voice system hobbyists, and developers working with embedded systems or cross-compilation. If you are only looking for general explainers or beginner tutorials, the content may feel relatively advanced.
The domain uses .cc, and the author lists Guangzhou as the location. Based on the content, reading the site does not appear to require logging into any overseas platform, so it is likely directly accessible from mainland China. However, GitHub comments or external links may be affected by local network conditions.
