Ham Radio And Shortwave Links

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...

For my taste to much talking and not enough facts.
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.
