In this first idea, the colours used show that the 'r' belongs to both 'hr' and 'rss'. The radio wave symbols aim to be recognizable while not too similar to those in the RSS logo.
Thank you for the feedback. Tried some variations with the radio signals: to emphasise the radio signal emission, a third wave has been added to the s. The lowercase aims to give off a friendlier 'community' feel.
Different positioning of the radio waves. Added a fourth one which creates some vertical movement balanced out by 'LIVE' on the bottom left. I will upload some variations to the signals themselves very soon
