  • I now have a random wire antenna ~16m long (though not straight and the very ends wind around the structure I’m using to hold it up which I’m sure is not ideal), a ~4m counterpoise-ish-thing, a 9:1 balun, and cable to the SDR.

    I’ve gotten wefax (though in negative and spotty, so still some figuring out to do). Still no IBP beacons at all, though.

    I have fldigi working to a degree using soundcard as input. No hits using a regex of the beacons’ callsigns (including the one here in Japan) on any frequency I’ve tried. Not sure why that is yet.




  • I grew up in rural Ohio and spent time in rural TX as well for a brief period. As a kid, I walked about 20+ minutes to bail hay in my neighbor’s fields in the summer for cash. I am currently farming in rural Tohoku Japan.

    Certain things are similar and certain things are different. To call where I live a suburb is just wrong yet we, and those even more rural than us, have fibre. I looked at buying land on the side of a mountain before buying this place and, although I’d have to pay for the run from the nearest point, I could still get fiber. Being Japan, I of course had to apply by fax machine, but the infrastructure is there for most of the country, both urban and rural.

    Edit to add: we have multiple fiber companies as well, at least one of which being a fully private company.






  • So far no luck, but I only seem to get flights when they are going to/from the nearest airport to places south of me; everyone else is going around. I’m not sure how far the range is meant to be (EDIT: 370km or so per wiki). I can very faintly see something on the frequency, but Dump1090 isn’t catching anything.

    I have some parts coming today to try a ~20m random wire antenna. I got 2x20m copper wire in case I need to do a counterpoise on the other side (which seems to be like 1/4 length (so 5m) of wire?).

    Edit: also apparently it’s not required in Japan, so I’m guessing that’s why nothing domestic at least has it. Maybe if I leave dump1090 running long enough, it might catch some international flight, but none seem to go that near me.





  • I think there are some other areas that have a lot more to worry about than Tokyo. I don’t remember for sure, but I think the expected path this time would be north in Yamanashi (I looked into what predictions were when I was house-hunting a few years ago).

    “Are there actually any signs of eruption?” said Shinichiro Kariya, a 57-year-old hospital employee. “Why are we now hearing things like ‘10 centimeters of ash could fall,’ even in Tokyo? I’m wondering why this is happening all of a sudden.”

    I’m shocked that this is news to anyone. Most schools send kids to a disaster prep field trip at least once where they would cover all this stuff. I guess maybe some part of Japan doesn’t talk about it, but there have definitely been TV shows about it, even in the decade I’ve been living here.
