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
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
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?
We’re on the air! “DC KILOVOLTS” is a pretty terrifying measurement, isn’t it?
It’s time for quarterly #transmitter maintenance at one of my sites today. I always enjoy this one because I get to light up this #VacuumTube powered beauty and put it on the air! Ever since I had that Flexstar exciter repaired, it can even do HD Radio on a tube!
I hear we have a lot of new friends on the fediverse. If you’re looking for good #FediFollows, here’s what I toot about:
#AmateurRadio - I was licensed in 2011 and now hold a US Extra class license #Broadcasting & #BroadcastEngineering - I like to joke with my ham radio friends that I turned pro. I have bigger toys now and I like teaching people about career opportunities in broadcasting.
Of course there’s also some random thoughts and cat pictures. Come say hi!
I wrote a script for a video about the evolution and history of the Emergency Alert System and how it relates to the broadcast industry (aka more effort at teaching you about it rather than slapping together a compilation of tests from the 1970s and 80s). It’s six pages long. I’m sorry in advance.
Not that those compilation videos of old EBS tests aren’t interesting, they just don’t teach anyone much.
