The reason I was looking on Ebay and bought the old Codan - on a friends boat, night time, half way between Broken Bay and Port Stephens a couple of months back - no mobile phone coverage - called Marine Rescue on VHF multiple times - no reply - out of range.
Called for a radio check on 2524 - immediate answer. HF no use for coastal cruising? I dont think so, some waffle happening from obviously armchair sailors in this thread

I think Kankama is right about DSC my next step up will be to get a radio with that, but too expensive right now. And Datawiz I will call you and talk to you with my useless HF radio
