#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..
My H2X Comms Headset Adapter is now available to order on Tindie!
Have you ever wanted to use your own 3.5mm TRRS in-ear headset to listen or talk on Comms?
This adapter converts 3.5mm TRRS stereo+mic headset to mono 4-pin XLR comms connector, as used widely in broadcast, live events and theatre.
The circuitry and receptacle fits entirely within the high quality Neutrik XLR-4FXX connector, so there’s no hanging dongle to get caught on things.
It also has a purple boot and label ring so it won’t get mixed up with other XLR gear in the control room.

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
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
