Re: Pointless Golden Record
Unintentional Radio probably only has about 5 light years range. Intentional Beamed transmissions maybe 100 light years range. They are unlikely.
So other than very near stars, SETI via radio isn't going to work. Also civilisations may only use high power transmissions terrestrial less than 100 years and then only local lower power broadcast, Satellite (very little into space) and cable / fibre.
