Most of this Web site is in German. But quite surprisingly my ham radio and shortwave link lists attracted
quite some readers from outside the German-speaking countries. So I extracted the English-language links and moved
them to this page. In the meantime this list got to large for my authoring tool. So the historical and BCL links
got their own page – see on the left.
If you have some command of German you might be interested in my German link list.
Ham Radio Link Lists
- Yahoo Directory: Amateur Radio
- A large link list
- Mostly a large link list centered on ham radio technology
- American QRP Club: Link List
- QRP projecs, clubs and suppliers
- AC6V: Amateur Radio & DX Reference Guide
- A large, lightly commented Link List and AC6V's own content. Many links are dead or link to Web sites
that have not been updated for years. If you are interested in MS Word 3.1 this is your source.
- XE1BEF "More Than 20.000 Radio Links"
- Besides his own DX reports Héctor offers many sorted links. Beware of the ads that the Web space provider
inserts as soon as you follow any of the links.
Ham Radio Blogs And Podcasts
- Offgrid Ham
- A blog about electric power supplies without a power grid connection.
- "HD TV shows dedicated entirely to amateur radio"
- ICQ Podcast
- Ham radio news from the UK
- A quite unusual podcast: A group of OMs and YLs discuss a specific topic on am Echolink conference.
The ham radio link is the medium as only hams may access the Echolink system due to the RF gateways.
It is not the topics as they vary widely.
- Practical Amateur Radio Podcast
- Jerry gives practical advice.
- Linux in the Ham Shack
- 10 min into episode 103 I had heard *nothing* about the official topic of this podcast...

- Amateur Logic
- A video blog living of visits to companies, ham fests and other interesting sites.
The OMs use their medium quite good, but the file sizes are enormous from 100 MB for the lowest resolution
- Solder Smoke
- Soldersmoke is issued once a month or so. The author is an enthusiast but not so deep into technology;
I would not discuss the death of a single small-signal transistor for 20 min. In my view the most interesting
aspect was the author's view of foreign countries. As a diplomat he has seen his share of those. But since he
returned to the USA this aspect has nearly disappeared.
