Practising amateur radio is almost 100 % indoor activity. Another hobby that I sometimes do practise is birding, a perfect outdoor activity, especialy during bird migration periods. Yesterday was a wonderful spring day here and my friend Lennart and I went for a very long walk in a famous birding spot area near Stockholm. Photos are here.

Well what have birders (and ornithologists) in common with amateur radio? They are also using radio communications to some extent. I will come back to that later on in my blog.
