   FCC DOES AWAY WITH BAUD LIMITS ON HF! OMG! I can't believe they finally did it! This is a huge, huge win for hobbyist digital radio communications. #hamradio

     @cmdrmoto @LambdaCalculus It's been an *EXTREMELY* long time coming. The rule should always have been "do whatever you want, but sign your signals and keep it to a bandwidth comparable with SSB (e.g. 2.8 kHz)". We're free to experiment with the available bandwidth slot like we always should have been.

     @roadriverrail @LambdaCalculus At last! 300 baud is fun for remembering my old BBS days, but not much else

     @cmdrmoto @LambdaCalculus I honestly suspect it was a rule made at a time when the main digital mode was RTTY and there was a strong correlation between symbol rate and bandwidth use, and it's just sat there as a fossil rule ever since.

     @roadriverrail @LambdaCalculus For some reason my gut is telling me that if I dig deeper into the “why”, I will discover that it was influenced by heavy lobbying from AT&T, back when folks were buying second phone lines just for their modems

     @cmdrmoto @LambdaCalculus AT&T and the Bell System were total shitheads and it's reasonable to want to blame them first. Like...that time they sued a company for putting a little cup on phone receivers? Shithead move.

     But if it was about kneecapping data transmission on radio, they'd have gone after VHF/UHF, too. Ham packet networks on those bands were massive and used as essential infrastructure.

     @roadriverrail @LambdaCalculus Yeah, my biases are showing, I think you’re right.

     I was halfway down the rabbit hole and moving towards a similar conclusion.

     @roadriverrail @cmdrmoto @LambdaCalculus I agree, it would have made sense to do this when ASCII was made legal on ham bands, back in 1980 or so.

     @amsomniac Yes, a bandwidth of 2.8 kHz, basically saying "do all the data you want, but don't take up more space than an SSB transmission," which is far more fair.

     @amsomniac I'm reinstalling mine the moment the leaves stop falling. The lawn guys accidentally destroyed my last one (weed eaters hit the tie down lines, antenna fell out of the trees, lawn mower drove over it)

     @amsomniac I seriously might consider a compressed gas gun this time, though it's also about finding some new trees. too many branches, and it's hard to get the lines up.

     @wholesomedonut If you can fit it in 2.8 kHz, it can now be done.

     I wouldn't say it'd make a backbone for modern data needs, but maybe for transfers where you're willing to "get it eventually" over long distances would be useful.

     @roadriverrail

     DUUUUUUUUUUUUUDE.

     See, I was thinking _small_ with doing a LoRa kinda network on like, a neighborhood or town scale, as a kind of poor man's WAN that could stand on its own two legs despite issues with hard infrastructure due to disaster or some kind of nefarious act.

     With this kinda stuff now wide open?

     Homey

     We're worldwide now

     @sxpert @mmu_man I don't know for sure, but I suspect it's a fossil from an era when modulation rate was tightly coupled to bandwidth. It wouldn't surprise me if it was a rule based on old RTTY hardware.

     Note the FCC has proposed rulemaking out now for VHF/UHF too, so we might see a Renaissance in packet radio there, too.

     @roadriverrail @mmu_man why was there a dumb limitation like that to start with, impeding the experimentation part of the hobby ?
