And this is a sneak peek at the modem project I am building that needed the spectrogram to make sure the PHY layer and all the primitives were working correctly.
This reference client (pictured, I like the win95 aesthetic, also written in C/Raylib) will be free software but the mLink modem itself will not be unless I find it impossible to monetize it. I have spent about a year and a half on this project.
mLink is a robust shared channel pub-sub radio data link, that can have many concurrent interactions over the air, with excellent fault recovery and many automatic premium features, such as compression by default, end to end encryption (if you are an authorized station), differential , automatic relay request on fail, and can transfer about 2400bps gross (much less net after error correction) in about 2800hz of bandwidth, at about 0db. Below that it drops substantially, but even so that is excellent performance in marginal conditions.
Its organized into three spectral regions on the air:
Emergency 8fsk modulator that can be decoded down to -21db (inspired by WSTJ-X) and generally get an emergency signal out no matter what. These encode 11 bytes each and last about 10 seconds.
3x (concurrent!) Announce QPSK modulator, encoding 11 bytes, works about down to -9db, and lasts about 3/4 of a second.
One "Bulk" OFDM frame that lasts about 5 seconds, and can encode between 600 and 950 bytes per frame (I vary the LDPC encoding rate instead of the modulation scheme to 'go faster on a good connection' (nobody does it like this I think)
I had worked on ARDOPC a couple years ago and it taught me a lot about how to work with modems, and I have a lot of experience with data links in the Navy on the P3 Orion and in general with different amateur modes and the problems that happen while using them.
I aim, with mLink, to take the best features of my 12 years of radio experience, and build the very best possible, fast, robust and easy for the operator to get what he needs.
@Phil Very strange. Southern europe has managed to survive for thousands of years with these temperatures.
Somehow, humans apparently have been genetically modified, so that temperatures above 21 C become lethal.
Buy an AC, go outside, buy a fan, drink water, stay in the shade. It really isn't rocket science. If the spanish survived so will the british.

Henry Nowak could have been saved if the police had helped him instead of arresting & handcuffing him!

@matthew Not only that, it is just plain silly. As long as the code quality is good, who cares if someone wrote it himself, or with the help of an llm?
@freepatriot In fact, you could argue that the west won by _spreading free thought around_.
@Dan_Ramos Excellent! Sadly I doubt this will ever happen in europe, the socialist center of the universe. =(

Good. It was immoral sexual bullshit.

@r1w1s1 Got it, thank you. I was just curious if I missed something about nvi that I should be looking into.

A There should be a law that there should be a trial by jury to decide if attorney generals involved in approving prosecuting of men on false sex crime allegations should be thrown in a wood chipper every time a man is found not guilty of electronic sex crimes without hands on offenses by a jury
B There should be a law that Men accused of electronic sex crimes without hands on offenses by an attorney general and found guilty by the court system should be thrown in a wood chipper
@fosserytech True. We must be optimists. Anything else leads to defeat.
@Harald @PeaceandProsperity @freepatriot Ahh... that makes sense. Then you could just leave your money, in USD, on a bank outside the country, and no matter what they do, you should be alright.
A very interesting perspective!
I'm in the middle of life, so naturally I think of my money as something that will grow over time, and how to minimize the taxation of the growth.
@r1w1s1 This is the way. But why nvi instead of vim or neovim?
It is interesting as a teacher, when teaching people with only ipad or windows experience. After my linux class, about 10%-20% of the class come to me and say they had no idea that it was possible to become so fast at accomplishing things on the computer. The terminal opened their eyes to a completely new way of using computers. They go on to become great technologists.

The UNIX shell is still one of the best IDEs ever created.
grep/find/sed/awk/make/ssh/git/nvi often compose better than many modern “integrated” environments.
Small programs connected together still scale surprisingly well.

@PeaceandProsperity @Harald @freepatriot One disadvantage is the political instability of south america. If the kirchners come back, its right back to socialism with high taxes and currency controls.
@charliebrownau You are a wise man!
@matthew Ahh, got it. Since I work in the business, there's pretty much no choice but to accept it and get on with the job. =(
