@tek_dmn As far as YSF vs other digital voice modes. Your best bet is to look at what is common locally. You can use any of them to link into whatever via a hotspot, but if you have a local digital repeater, you will need THAT mode to use it.

@tek_dmn It's very much of a cool Swiss army knife that does many things, but has some shortcomings you should be aware of too.
1. You will need to study the manual and play a LOT to get everything. It's not intuitive.
2. Shortwave is AM only, and has very poor sensitivity. It's kind of an "also does" thing like the crappy scissors on your Swiss Army knife. A $100 tecsun will blow it out of the water.
3. APRS for GPS tracking works fairly well. It's reception of APRS packets isn't the best.

@youseeatortoise @martennorr Love these maps! The choices hurt my brain though. Lake superior is almost 200m above sea level, and it's inundated, yet parts of FL that sit a few meters above sea level are islands? The worst case scenario for the great lakes isn't sea inundation, it's drought causing them to drop. Still, thanks for sharing. Fun to look over.

@LeftistLawyer There's nothing about GPS technology that requires any sort of tracking, cellular plans, planned obsolescence or any other sort of enshitification. Those things are all add-ons. GPS is a receive only technology, and a nav system requires updating maps every few years somehow, which can be done on your home wifi. It can be built-in and just as simple and robust as an old Garmin.

@salubrium If you can hear it but cannot open it, then you are likely within 10db of working. Going to a decent antenna, like a 1/4 wave ground plane or j-pole up high will often do it.

@IU1KGS That, and all the Versa Tuners are fantastic tuners for the money. Only 2 caveats. First, always open them up and look over all the solder connections with a magnifying glass for bad joints (these are really nice and spacious inside, really, take a look!). Second, don't use that 4:1 balun. It's garbage. Too small a torroid and a crappy voltage wiring make it basically useless. There's lots of space to replace it with a better balun as a future project though.

@k0in @salubrium That's a good take. The proof is in the pudding.

@HopelessDemigod @kilroy_was_here I would use the "3% critical" column in that chart. Lots of amateur transceivers transmit poorly at a 10% voltage drop. Then again, How often would you be drawing 100A? Designing to perform optimally at 50A, and "just" safely at 100A would be fine in most cases.

@salubrium It's fairly difficult to get a good measure of the SWR of a HT antenna because of the widely varying ground plane. You could say that placing it on a real groundplane might be more accurate measure of the antenna, but then you are not simulating the actual real-world application of the antenna. If you place it directly on the VNA, the ground plane isn't going to be the same as holding an HT either. Happy to hear what other hams settled on as "good enough"

@Steve
Did you watch the recent Climate Town video about the push to use natural gas as the "bridge fuel" between dirtier fossil fuels and renewables? It talks about this whole thing. Really interesting.

@RosaRossa@kolektiva.social While that's great, not everyone can work from home and not everyone can get to work by bike or public transportation. And transportation is an important sector but not the only one by any means. @ve3mal

@Steve @ve3mal Right? Let's transition by doing the thing we're already doing but in ways that make you think we're changing.

Reminds me of the huge ramp-up in plastic usage that's been going on for decades, with the fossil fuel industry planning on increasing plastics usage 3x by 2050 (you know, to "compensate" for EVs not using gas).

@ve3mal @susankayequinn A closely related phenomenon is talking about fossil fuels as a "transition" to renewables. Apparently, we're meant to believe that the way to make a change is by not changing anything.

@susankayequinn My favorite brain-breaking propaganda is "We can't stop using fossil fuels overnight!" -It hit's all the buttons. It's a) technically true, b) not what anyone is actually advocating, and c) ALWAYS leads to the logic that less or nothing should be done right now to start transitioning away from fossil fuels.
It's used to sell pipelines, expanded oil extraction, kill renewable energy projects and even basic economic incentives for transition.

I recently came across Kiwix, an offline website application. It's fascinating how slick it is. On both my phone and laptop, I loaded some of the smaller sites like top wikipedia, some stack overflow topics, the arch wiki, etc., and it can full text search everything at once, lighting fast. Better than the online websites or using a search engine! And useful when away from internet! Take a look: wiki.kiwix.org

@Npars01 @WJBL @GottaLaff @lolgop Why would a "taxpayer's federation" not be funded by actual "taxpayers"? He asks knowing the answer.
