British Telecom 8746 telephone set, connected to Asterisk VOIP PBX via Grandstream HT802 v2 ATA (which works with loop disconnect dialling)

Testing an old VCR to see if it works (these videos will later be captured to digital)

Something I've wanted to do for nearly 40 years, but never got the chance to borrow one of these things when I was at school..

Testing with a cheap 12V 3A SMPSU from China, instead of the bench power supply

connecting L+12V to the RF power amp, the analogue radio in the workshop is desensitised due to the large amount of RF

EN: Sending various dynamic RDS radiotext which changes every 28 seconds

Si4713 spectrum on SDR

RDS/RDBS display showing dynamic radiotext

Si4713 controlled by Arduino connected to small RF amp (I suspect only about 100mW power, that SWR/power meter isn't the most accurate)
