ahh one of the best here http://www.radio10gold.nl/players/webcam.html provides a full audio feed and when the jock fades the mic the webcam ‘jumps’ to a close-up shot
R10G used to run with JAM jingles thru Top Format but these days have some equally very nice Top Format custom material … it’s fascinating to watch the jocks at work, a lot of energy in the delivery & interesting to ‘anorak’ it up at the production / pre-recorded calls etc they work on in between the songs 
*** checking today they do pick & choose ‘live’ webcam times but it is worth a watch when they are streaming
