WSUN-TV, UHF analog channel 38, was a television station located in St. Petersburg, Florida, United States.

Later in the fall of 1953, however, the area's main telephone provider, Peninsular Telephone (later owned by GTE), provided WSUN-TV with a private microwave link in time for the World Series, making it the first television station in the country to receive live programming via microwave relay.

Until the All-Channel Receiver Act went into effect in 1964, television set manufacturers were not required to include UHF tuning capability.

Also, UHF signals did not travel very far at the time, resulting in a considerably smaller coverage area compared to those of WFLA-TV and WTVT.

Shortly afterward, ABC decided to move its affiliation in Tampa Bay to the new channel 10, effective with the end of WSUN-TV's contract in 1965.

Channel 10 officially joined ABC in a special ceremony on September 1, leaving WSUN-TV as an independent station.

The new station's owner, Hubbard Broadcasting, used its financial muscle to snap up most of the stronger syndicated programming.

WSUN-TV limped along for two more years before finally going off the air on February 23, 1970; the station's owners cited that "the situation as to viewers and advertisers precludes continued operation at this time.
