Looking over Donner Lake

Interested in learning more about Me?

Listen to the Hamdom Thoughts podcast by AD6DM interviewing me about Ham Radio, Making, Hacking and SOTA

Ham Radio, Summits On The Air (SOTA), Making and Hacking and Vintage Electronics are hobbies that I enjoy. This website covers my activities in these hobbies. See my personal website to learn about my IOT garden and photography. You may also visit my QRZ.com page for my Ham Radio profile.

A ham goes into a bar and orders 1.000009 root beers.

The bartender says "I will have to charge you extra for that because it is a float."

The ham responds "In that case, you might as well make it a double!"
