I got exactly one picture of myself in this adorable outfit, and I'm flipping off a petulant transmitter that can't take a little bit of heat.
(Honestly it was more than a little bit. Glad I wore my mesh corset.) #broadcastengineering

Docker in Production Engineering: What Actually Belongs in a Container
The production industry still runs on a surprising amount of fragile infrastructure. A critical automation script lives on a programmer’s laptop. A utility app runs on an aging Mac Mini under a desk. A show control tool is configured once and never documented again because “it works, don’t touch it.” A monitoring dashboard was built three years ago by someone who no longer works there. If you have worked in live production long enough, you have seen systems held together with static […] -

RE: https://graeber.social/@DGI/116500891053079405
When I worked in #BroadcastEngineering in late 1990s, I saw then high tech kit which could have been used for making better #TV programmes (especially live broadcasts) instead being deployed to reduce headcount at TV stations and merge their playout centres (which is how UK commercial broadcaster #ITV went from 16 regions to just one company)

Limited vs Full Range Video
HDMI, DisplayPort, and SDI — What Engineers Keep Getting Wrong If you’ve ever seen: Gray blacks Crushed shadow detail Blown highlights A “washed-out” LED wall A QC rejection for “illegal levels” There’s a very good chance you were dealing with a range mismatch. Limited vs Full range video is one of the most misunderstood topics in AV engineering. And the confusion only gets worse when you move between HDMI, DisplayPort, and SDI. Let’s fix that.

#NHS Estates gave security clearance for pictures of the #transmitter #infrastructure of #Ipswich #CommunityRadio to be published, you can now see what me and my friends hauled up to the top of the Maternity block and installed in the plantroom..

its also an indictment of the decline in public service #broadcasting that #STV (which used to be a European leader in #BroadcastEngineering as recently as the late 1990s/early 2000s) could only release a vertical #YouTube video and not even show the televisor in full action..

Students in #Scotland have rebuilt a modern replica of the original #television set invented by #Scotsman John Logie #Baird - in time for October, when it will be 100 years after he first demonstrated it was possible to televise moving pictures.. #TV #BroadcastEngineering

1985: me and my friend from highschool experimenting with 2 transistor home built FM #transmitters, later #Stentor kit from the #Netherlands, transmitting between 105,6/105,7/105,8 MHz (depending on how much TX had drifted) and putting 1km "not spot" into comms for British Rail and Reading Buses on their then new Stornophone #VHF radio schemes (which bizarrely had mobile TX on 150+MHz and base on 105-106 MHz (this portion of the band wasn't officially allocated to broadcasting back then!)
2025: working with my friends at #IpswichCommunityRadio doing it all legally on 105.7 - 50W TX power, stereo, digital soundprocessing, dynamic RDS, about 30-40km range, full telemetry on the transmitter and bandpass filter so we don't upset anyone else on the band.
Listening to Em's 80s Hour of Fun last night (she featured 1985 on the episode) reminded me of this (and that 40 years have passed since I started being involved with #radio!)
(en eindelijk na 40 jaar kan ik ook de andere kant van de bouwfolder (die was in het Nederlands geschreven) voor de Stentor lezen!)

The #Coomber schools #radio cassette pulls in the signal from #MidSuffolk even with just its internal #antenna (it does have to be in a particular part of the office to get any reception, but it works better than many modern receivers) #FM #VHF #BroadcastEngineering #CommunityRadio #Ipswich #Suffolk

Monitoring the #transmitter #telemetry, dynamic #RDS and the audio on a car radio from #MidSuffolk (it is good, no overdeviation and the endstage is staying at a constant temperature of around 35 degrees Celsius)

The new #transmitter I tested last week was installed at #Ipswich #CommunityRadio today in plant room of the general hospital (antenna is on maternity block) along with a SIM for a better LTE network, we now have full 50W output and full telemetry/control available via the PC (which also does #soundprocessing and #RDS ), so I can check all this is working (including keeping an eye on the FM deviation and TX endstage temperature) from home or my office 20 km away.. #BroadcastEngineering #Suffolk

Waiting in one of the car parks of the general hospital for the rest of the crew to arrive, today we are moving the #CommunityRadio #transmitter to the roof of the Maternity block. Alas, NHS won't allow me to share photos of the installation for security reasons (there's a lot of critical national infrastructure up there!) but #Ofcom are allowing us more TX power and it's a really good location, should get a few more km range on #VHF / #FM

Got in the car, tuned into the #CommunityRadio station - to be greeted by dead air (not even silence detector) but #VHF carrier and #RDS present - not good - Ofcom does not like that! As soon as I was back home and in front of a computer, checked our streaming PC - for some bizzare reason the audio link stream to the TX has stopped. Restarted it and we are back on air on Band II ( VHF / FM ) #BroadcastEngineering #radio

Oof. Long day tomorrow. I have an FM translator misbehaving up in Green Bay. So, I have to go to Sturgeon Bay to get an FM tuner out of storage, drive back to Green Bay to install it, and then as a side quest, run over to the studio and install a new firewall. #broadcastengineering #radio #broadcasting

What I’ve been doing these days. #broadcastengineering #radio
-
We got new #soundprocessing software for the #CommunityRadio station in #Ipswich #Suffolk - testing out various presets and settings (don't worry, I'm not driving at the same time as doing this, its just that most of our FM listeners these days are using car radios)
The soundprocessing cuts in when you hear the glitch in the audio, there is a delay due to studio-transmitter link being an internet stream and the current programme is already quite loud #radio #BroadcastEngineering

This video I’ve been working on since November is finally complete! Now I just have to write a description, create a thumbnail, and schedule its release. Video essays are exhausting… but I absolutely cannot wait for you to see it.
It’s all about FM. 35 whole minutes of video about frequency friggin’ modulation, the guy who invented it, how and why it works… complete with some mind-blowing technical demonstrations.

I much prefer cutting rigid coaxial transmission line to length using a miter saw than soldering a PL-259 connector onto some RG-8 coaxial cable… just sayin’.

I finished the first draft of a script for my next YouTube video today. This one will be a doozy…

I may have gone a little overboard for my next video, but I think the super nerds in my audience are going to love it!

US broadcasters: the FCC has GRANTED (partially) a petition to delay the CAP prioritization deadline for EAS equipment by 90 days to March 11, 2024, but ONLY for participants using Sage Alerting Systems devices that the required update is not yet available for.

my coworker has apparently used my same method of clearing out wax and moisture in those little coily IFB earpieces by using the air compressor so it launches the junk into low earth orbit, except he neglected to aim the other end and it launched it in his face
please ensure the Yuck Cannon is aimed away from your face before firing

As a follow up to the latest video, I put together a fun little calculator that can calculate ERP from TPO, line + insertion losses, and antenna gain. It can also give you the TPO needed to achieve a given ERP!

NEW VIDEO: Radio stations aren't telling you the truth when talking about how much RF power they use. Neither are government regulators. OMG IT'S A CONSPIRACY!!1
Plot twist: they actually are all telling you the truth. It's complicated, but I'll explain how and why with a little math.

Yesterday: mentioned a random shower thought idea I had to a coworker in passing.
Today: Program director, operations manager, GM, and corp VP of engineering all on board, and 98% of the plumbing is done.
Tomorrow: Final checks, additional planning, probably a couple of phone calls and production work.
This weekend: it's live?
Yeah... working in #broadcasting is fun!

New video: Who’s That Pokém… wait… Who’s That RF Component?! Learn about this mysterious device, what it does, how you can use it, and how it works. Don’t get too dizzy… it’ll spin you right round.

Now that I have a video releasing in about six hours, it's time to think about the next one. Who wants to learn about this thing?
