Es gibt Bands, die darauf bestehen, nur im Dunkeln aufzutreten, wegen deren „geilen Visuals“ und dann stehen da zwei Beamer auf der Bühne, die Filmchen im Stile der späten 90er an die Bühnenrückwand werfen.
#Transmitter

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

I put the #Si4713 #FM #transmitter board, Arduino and a smol #RF amp (+20dBm) in 2 cardboard boxes that previously contained Google Beacons, having lined these with copper foil to create a better RF earth.

More stable than previous setups on breadboard (the Si4713 is easily upset and can glitch/cut out the RF output). The amp module is just enough power to cover a few hundred metres (without attracting unwanted attention) and not too fussy about antenna SWR #radio #electronics
