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

TX50 on a desk with a dummy load
First test with only 19KHz pilot tone present and no programme audio, to check the TX has PLL lock and works at 50W output
Using the car radio to monitor the audio and checking the TX site PC (I am safely parked up, it would be highly illegal and unsafe to try this whilst driving!)

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
