And it was a pun by Ericsson engineers, as they used Erlang to program telephone switches where the capacity planing included Erlangs.

And Apple was involved in that as well, even if it was not planed. The pod in podcast coming from iPod after all.

Yeah...

But only for those areas with receiver coverage that feeds them.

But your own receiver will always cover your area.

SMS routing and billing systems did cost money. Especially billing, as the standards had nothing for it, so it was done by 3rd party software for a very long time.

M12 gets old quick if you do a lot plug/unplug cycles.

Not a single telco wants this. So it does not get built.

Interestingly DECT NR+ is a 5G standard on dedicated spectrum and has been designed to be a mesh from the start.

Viasat fixed modems got bricked at start of the war in Ukraine and some collateral one's in border areas.

The cheapies are less useful for debugging real problems, due to their bad UI and severe limitations.

A good, fast reacting multimeter is likely better thing to get than a cheap scope.

That said the cheapies might be usable for debugging audio stuff.

Can be done more cheaply if tou are good at reusing things and building.

Exploding The Phone was an excellent read.

Proper PoE sources have active per port current monitoring and will disable the PoE power in case of an over current event.

Good documentation and support.

All mosfets are like that. The marketing folksbL at Toshiba just were not able get it removed, or they have had one too many complaint from folks running them near the absolute max while not cooling them properly.

Apparently in September 2017, when they introduced the SPARC M8.

Naturally there needs to be filtering and some sort of analog frontend. My main point was that mainstream rigs now do direct sampling, instead of zero-if or superhet with dsp IF.

And WSPR sure is magic, people do thousands of km with it off an rp2040 gpio pin.

The popular IC-7300 transceiver from Icom does that. Receiver samples the whole band and does downconversion in the digital domain (DDC) and same for the transmitter (DUC).

On the hobbyist side there is the TRX Wolf by UA3REO.

Interesting project. They have definitely raised the bar for FOSS ECAD software with their major contributions to KiCAD for example.

He owns 84% of Automattic, so likely not.

>Patent unencumbered in a way that someone could make a commercially viable implementation.

Doesn't this exclude all modern cellular standards then?

I guess you had safe search off?

So have the stressor and stress testing DDoS for hire sites changed to scraping yet?

The Yahooification of Googles search becomes more amusing when one considers that it is now led buy the dude who ran Yahoo search to the ground.

Sounds like an easy target for DoS.

UV-K5 does cost 1/10 to 1/20 as much as the handhelds did 20years ago. CB's seem niche and to this day the handhelds don't seem to go much below 100usd in price. Just not enough volume I guess.

In Finland parental leave is not fully covered by the government. So you get to pay both the original worker and their temporary replacement.

Same with Intel. And once the culture is rotten, things will be very hard to change.

That radio interference was the reason FCC almost banned alternative router firmwares ten or so years ago. The compromise that allows openwrt to exist is the radio drivers being signed binary blobs.

Folks were modifying stuff for more power, more "channels" and disabling dfs and apc. So it did not happen for no reason. And now vendors like Ubiquiti and Mikrotik have special USA models with more locked down firmwares.
