It is routinely done on paging simulcast systems via an rf or landline feed but takes more hardware and effort than the average ham could afford or support. It requires very high stable reference oscillators or even GPS sync,time delays on the audio portion and careful planning for minimal overlap.Even with all this,they sound funny,fuzzy and not the best quality. As far as I know,digital latency would make simulcasting impossible via any network connection making it impossible to keep the audio in phase.Better results on ham bands using two different frequencies,low tech,low cost but uses more bandspace. 73,Lee,N3APP,147.27 and 443.375 Erie,Pa Our 27th Year!
