SYRACUSE — No, that’s not a typo in the headline… Syracuse-based WRVD 90.3 FM will sign-off around 8:30 Saturday morning for some transmitter maintenance work.  Fred Vigeant, program director for the WRVO Stations says the outage will last “throughout the day.”  Parent station WRVO/Oswego and siblings WRVN/Utica and WRVJ/Watertown will not be affected by the outage.
