Hi all, No, DVT is not, in this context, the rate of change of voltage over time. But it is about things not changing enough.
I was thinking the other day about how many sequential hours we all spend sitting on a cross-country flight. This was on my mind because I have one coming up -- to Dayton, Ohio. Then I thought about an article I read recently, reminding me how sitting for long periods of time just isn't good for human anatomy. They say you need to get up every 20 minutes or so and walk around, stretch, feed your pets, get the mail, whatever. Anything but sit for hours on end. Pun intended. Why? DVT...deep-vein thrombosis. (I hear you saying, "WTF?" But in fairness, I did put "OT" in the subject line.) In short, prolonged inactivity can cause DVT and complications thereof. I'll spare you the details, as I'm not qualified (just Google it), and I've never had it myself. Let's just say the consequences can be scary. Then I thought of ham radio. At times we're at the inert, four-paws-in-the-air, bleeding edge of the bell curve in terms of sitting. Not just for hours. For some events it's large fractions of a day. With renewed awareness I now use nannyware to periodically break me out of a techno-trance. Though avoidance of DVT was never a stated goal for our product offerings, it's a happy coincidence that our portable gear gives some of us another excuse to get out of our chairs. In hindsight I can see the benefit to our customers at trade shows: they're more than their share of ageless, timeless, energetic and athletic. Anything that encourages movement is in this category, of course, from high-band HTs to bicycle mobile to climbing your tower. My advice...keep on truckin'. And thanks for the bandwidth. 73, Wayne N6KR -- Elecraft, Inc. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
