Is there an app that will tell me how far away I am (as the crow flies) from a certain point?

Trying to get a more accurate idea of repeater ranges.

What if you just wrap some wire around a 2x4 and call it a Slim Jim?

"In the ensuing months, Ventilator 202 broadcast hundreds of computer programs. During the hour, Modli would announce when the segment was approaching, signaling to his listeners that it was time for them to fetch their equipment, cue up a tape, and get ready to hit record. In the case of games, users would “download” the programs off the radio and alter them—inserting their own levels, challenges, and characters—then send them back to Modli for retransmission."

"Because all the day’s computers, including Galaksija, ran their programs on cassette, Regasek thought Modli might broadcast programs over the airwaves as audio during his show. The idea was that listeners could tape the programs off their receivers as they were broadcast, then load them into their personal machines."

What's the cheapest way one might get into ?

I probably just need to save up for a good HF radio, but it would be sweet if I could get started around $100

Interesting. There is significantly less noise overall, but there were points at which the signal just cut out. That's what those black bands are. I suspect that's the wind blowing, but it could also be that there are things like trees and houses in the way.

I opened up WXtoIMG just to see when the next satellite pass would be and it was *right then*, so I disconnected my antenna from the transciever, attached it to my SDR and let it run for as long as the signal was coming in.

images from using RTL-SDR and a quarter-wave ground plane antenna. These are probably the best images I've gotten so far. Gets a *tiny bit* better every time.

When you apply for an amateur radio license in the US there's a box that asks if you've ever been convicted of a felony.

And I think that sucks.

Alright. Set aside the FCC (or whatever relevant agency for your country) and the ban on encryption over amateur bands.

Wouldn't it be possible to develop a protocol over which two or more people can exchange encrypted messages unintelligible to people without keys, on one common frequency and mode, without packets colliding, and without crowding the band?

I finally managed to run coax into my house last night. Talked on a local repeater and they said I sounded good.

Instead of drilling a hole into the wall I just used some really thin (2.7mm) coax and a SO239 to SMA adapter and ran that through the window.

I still need to ground the antenna, so it stays disconnected most of the time. I'll be fixing that very soon.

Is there a way to measure SWR without an SWR meter?

I mean, I can buy one. I just don't feel like it rn.

The line "After this operation, XX.X kB of additional disk space will be used." is such a throwback at this point. A relic of common problems from the distant past, when people would actually have to *check* how much disk space they had to see if they could afford to perform these upgrades.

Those lengths in metric should be 1.25 Meters, 17.5 CM, and 50 CM

Reposting as public.

Without having resolved the problem of *how* to run coax into my house, I have bought copper pipe and fittings to build a J-pole antenna.

However, I would like this antenna to resemble the Arrow dual-band antenna. for 2M and 70CM.

So, it would theoretically have the same dimensions as the Arrow antenna. ~58.5", ~6.5", and 1~19.5" for the elements and however far apart they need to be spaced, just with copper pipe and joints rather than aluminum angle.

Would this work?

Failed to pull an image from the , but we did see it fly over which was very cool.

has a built-in "AFSK1200 decoder" so you can read AX.25 packets directly from an .

Here are some local packets!
