  • I bought a KX3 as a reward for completing a very difficult certification. I earned that $2500 radio, but dang if I’m not scared to actually take it anywhere because it feels so fragile for how expensive it is. I included the battery compartment when kitting it out, but ended up removing the batteries and relying on an external LiFPO battery because I didn’t like cracking the radio open like a clam every time I needed to change them.

    Something like this would make a whole lot more sense for my QRP needs. It’s far, far cheaper and looks a bit more sturdy.






  • When you say it like that, it sounds really mundane.

    Ignoring the how of it all, here’s how I imagine it working subjectively. They have a much wider visible spectrum compared to humans, but they can’t perceive the whole thing all at once. They have four pairs of nictitating membranes that act like bandpass filters. Between the bandpass membranes and signal processing in the brain, they “tune” to different spectra, and can even narrow the bandwidth of the received signal. They can sense light polarization by aligning or misaligning their eyes to the direction of polarization, and because their eyes don’t rely on focusing a light to a point, they can stare at the sun without harm or discomfort.

    Subjectively, they have no fixed concept of color, as objects appear different depending on how their eyes are tuned. Their languages lack simple color words, and must rely on analogies to objects that are similarly colored, much like most (Western) languages have no simple terms to describe odors beyond relating them to their sources (“earthy”, “fruity”, “floral”, etc).

    The low-end of their eyes’ frequency range isn’t set, but they can at least see thermal radiation emitted by living bodies, and the high end is set at the threshold of ionizing radiation. Because their eyes work equally well during the day and at night, they and other species in their clade that share the same eye structure are neither nocturnal nor diurnal, and have active and rest periods that do not sync with the day-night cycle. Upon achieving sapience and developing a structured society with the concept of timekeeping, they do not use different time zones.






  • an ARES group in a neighboring county set up an AREDN network. They said it worked very well, with two caveats.

    First was a jurisdiction issue. They couldn’t send climbers up to replace or repair equipment on their own, they had to wait for another entity to do it, this lead to things going unrepaired for a long time, which leads to…

    Second, WISP equipment, even outdoor-rated stuff, isn’t as weatherproof as one would hope. Where I live (gulf coast US) we get a lot of wind and rain, so things broke down often. Combine this with the inability to replace and repair equipment as needed and you get a perpetually flaky network. I think it’s no accident that the most active AREDN mesh is in SoCal where the weather is perpetually clement.

    This is all second hand, of course, though I can vouch for the WISP gear not being exactly Ragnarok proof. It seems when it worked, it worked very well, but it often didn’t work for the reasons above. If you can locate equipment in places you have access to, I think it’ll be fine.
