Could you provide some more detail around what you mean by ‘low level’. For example, what about a VFR cruising at e.g. 6,500’.
Personally, I would not advocate use of the Multicom above what altitude (AGL) you might be at around 10nm from the strip you intend to land at. As a VFR operation, you can listen to music if you want... and I understand many do….
In the cruise, good airmanship might suggest that you listen to Area or maybe 121.5 or one of the glider frequencies if around a gliding area or whatever you believe you might get the best relevant info from.
This discussion seems to rely on too much reliance on talk and not enough on keeping a good look out. It does of course help if those with radio are on the same frequency. Shame that CASA don’t understand that… Is the “S” for Safety or Stupid???
