3pbs FM melbourne keeps dropping out

Hi,
Local radio station PBS FM continually drops out on Roon Radio.
It works fine when I stream via Sonos or on my laptop and only seems to drop out when played via roon

As per screenshot, there are two streams to choose from. Both of them suffer from the same issue

I get the same dropouts through Roon. Plays fine through their web player.
Their streams are pretty poor quality though. 64kbps AAC sounds awful, all other streams come through as 1-channel mono.

I’ve just added a third stream. Any better?
