Mr. Rawles, M.E.R. makes good points for the practice of journaling. I, too, encourage the activity. I would add a related activity – logging. No, not cutting trees, but recording activities, events, and details. I do my journaling within my log. I am not big on “my feelings”. I am more about doing what is needed and savoring the feelings later. Better? No. Different perhaps. I have found logging to be extremely valuable. My log has been computerized for decades, but lends itself to the same manual media as presented by M.E.R. I have recorded diverse events for years. I …

James: What M.B. is describing in his letter “Post Disaster Wi-Fi Commo Networks” is ideally served by a mesh network. I’d suggest starting at the Open Mesh web site. Click the Support link for tutorials and frequently asked questions (FAQs). If you want to link up a neighborhood this can work fairly well. Mounting the radios outside helps considerably and will often be required as the 2.4 GHz signal doesn’t penetrate obstructions very well. Existing wireless routers, old 2.4 GHz cordless phones, etc may interfere. If radio links are more than a few hundred feet apart you’ll need to get …

The recent article: “Built-in Obsolescence, by Margaret G.” prompted me to comment on personal computers. I am a die-hard anti-Windows guy. The troubles caused by the easy subversion of your own computer by bad people combined with terrible permissions allowing user space programs to affect and jump to your whole network makes it a no-go operating system for people wanting reasonable network security unless you are a computer scientist working for the NSA or other governmental agency with a contract which allows you to review and customize the actual source code. While most windows boxes die a slow slide to …

Sir: One thing not mentioned in the survival groups web sites is the use of ad-hoc wireless wireless fidelity (wi-fi) networks. When me and several others put together a group plan, we came up with the idea of using wi-fi as a short range method of communication, information sharing and news distribution. We found several Wikipedia pages devoted to getting maximum range from a wi-fi router. Many of these methods can cover entire small towns. Enabling the password encryption features built into these devices can while far from perfect provide a super secure text and voice communication service when used …

Sir, Dave’s observations are quite true. There are some really good deals on older radio gear. I have a great fondness for these “Boat Anchor” radios. (Real radios glow in the dark and keep your shack warm in the winter.) That being said, there is a very real caution for the use of the old tube radios. My Kenwood TS-520 is mostly solid state with tubes for the output section to give more power than was available from the transistors of the day. The problem for the unaware is that these tubes have 800 volt power supplies with enough amperage …

Hello Jim and Readers, Last weekend I attended a Ham radio swap meet near Salem, Oregon. I have attended swaps for over 40 years now, and I am noticing an interesting trend in equipment sales. especially in 1970s and early 1980s ham gear. Kenwood, and Yaesu gear that was very popular during that period of time is becoming very affordable. Most of the Kenwood TS-520, and TS-820 gear is now selling on average for around $150 to $350 price range. likewise, the Yaesu FT-101 and FT-901 series are in the similar price ranges. Most of these older radios work quite …
