  • There are plenty of “compromised antenna” options for you; there are loads of amateur operators who simply run their antenna around the largest room in their apartment and make long-range communications. It’s not optimal, but it works.

    There’s a whole movement in amateur radio right now which relies on being light and portable. A 15 meter carbon fiber mast, some wire, 12v and 100W and you can work the world from a park.





  • It’s been a while since I setup my system, but as I recall they are interconnected via the smart hub, and do not need internet at all. When I first configured our system, IOT was probably the topic of an exploratory whitepaper and not yet reliant on internet. But times have changed! Give it a bit more searching; we’ve been happy for quite a long time with the devices. They even have plugs which you can convert dumb devices to a smart HA device—but you’ll have to get them on eBay because they’ve been discontinued:/


  • Caseta switches can handle 3-pole switches in exactly the way you’ve described. You could even set them up with dimmers, pico remotes (and eliminate one of the switches). If you get the wireless bridge (now known as Smart Hub) you might be able to tie it into your HA depending on your ecosystem.





  • I went all-in on designing one myself, but used lots of examples to form mine.

    Ultimately the things you need on your card are simple: callsigns, band, time, and signal report.

    Doesn’t have to be fancy or elaborate. Even a minimalist card is unique in its own regard.

    On the other hand, you can hire a graphic designer, give them some examples, and let them go at it.

    This tech (mondernized) is still in use!

    Here is an SSTV image I received as part of an image exchange with another amateur radio operator; I was in New Mexico and they were in Illinois:

    The “P5” is the image equivalent to a signal report.

    Depending on the encoding method, it can take some time to transmit the image, as each line is sent sequentially.




  • There are parallels to when autopilot first began to proliferate in aviation. I’d have to do some research to confirm, but I am certain there was at least a segment of people who would have said they trusted pilots to fly more than autopilot. Now it’s 99% autopilot. The pilots of scheduled air services typically hand control to autopilot fairly shortly after departure, and for quite a long time before arrival. In some cases there are even autopilot-coupled approach to landings… and nobody bats an eye.

    We collectively spend millions of hours in traffic, and lose thousands of lives to preventable accidents (like drowsy/sleepy/influenced driving).

    Aviation made the switch to save lives, and eventually drivers will, too.

    When we look back, we’ll wonder how we were such savages about insisting we drive manually.

    An interesting game to play when driving around the US is “Prison, or School?”

    The rules are simple. When driving past any complex with tall fences, quickly blurt out if it’s a prison or school. Then look for signage or check a map application to verify.

    You’d be surprised how often you’ll get the answer wrong.
