SW Radio Africa has gathered a significant audience in Zimbabwe - it has also attracted many unofficial correspondents who file news and information by mobile phone.
They will put anyone on air, so long as their stories are credible, or can be corroborated. There are some reports of violence against Zanu-PF; but Zanu-PF refuse to be interviewed.
Violence
In Zimbabwe, people listen from their homes in the cities, in groups around evening fires in the bush, and sometimes - to improve reception - from the branches of trees.
Listeners have called in to report beatings, kidnappings, and a catalogue of violence that has become almost routine. There are also accounts of missing voters' rolls and failure to announce where polling stations are located.
Intimidation
Some Zimbabweans say their ID cards have been taken by thugs - without an ID card, you can't vote.
There are rumours that ballot boxes may be opened, and opposition supporters identified.
There are even warnings not to shake hands before voting, in case you get ink on them: inked hands are proof that you have voted.
Observers
Commonwealth observers say they are aware of all these reports. But they will not release their findings until after the election week-end.
SW Radio Africa frequently assure their listeners that the various rumours are unfounded - that the ballot is absolutely secret. They also urge people to report violence to the police, and to the international observers.
Turnout
Opponents of Robert Mugabe are counting on a high turnout - but even if Morgan Tsvangirai's Movement for Democratic Change wins the poll, his supporters are full of foreboding: will the governing ZANU-PF accept a result that goes against them?
