"This is real radio; we are who we are," Harding says.
To have a successful radio show, you need to put your life on the table for everyone to examine, says Alexander, 35.
"Your whole life is preparation for your show," says Alexander, who also is the station's operations manager.
That means very little stays private, and they aren't afraid of embarrassing each other.
"If it's good show material, we use it," says Harding, 36.
Harding says she and Alexander play off each other naturally.
"He's funny with one-liners, and I'm more outrageous and wacky," Harding says. "I'm more likely to be a daredevil, and he's used to playing the role of big brother."
The Chambersburg couple started as a morning team Aug. 4, 1986. Alexander already was a morning show host at the station, and Harding had an afternoon program.
They will mark seven years of marriage in August.
Alexander starts the show at 5:30 a.m., and Harding joins him at 6 after taking their son, Jonathan, to day care. Their broadcast is interspersed with the station's mix of music from the '70s, '80s and '90s, and it isn't scripted in advance.
"We try to do whatever's best for the moment," Harding says.
After they sign off at 9 a.m., Harding starts planning their next show. She's always looking for interesting facts and off-the-wall tidbits that they can use for the show, which targets women ages 25 to 44.
Getting audience members to know you and like you is important in radio, Alexander says.
"Every day we need to make people feel some emotion," Alexander says.
Seeking listeners' advice
Listeners play a big part in their lives. When Jonathan was born five years ago, they sought listeners' advice on what to call him.
"It took two days to name him," Harding says. "We took a poll on his name - Jonathan or Brenton."
Harding says callers also gave them good tips about planning a party for Jonathan's birthday, which was Monday. They took Monday off to take him to Dutch Wonderland.
"Some of our best stuff comes from when we've been off a couple of days," Harding says.
Tuesday morning she told listeners about getting out the grill in preparation for her son's party, only to discover that it still contained food from their last barbecue.
Such personal glimpses are regular fare for listeners of Alexander and Harding.
In addition to sharing their experiences at home, the two always are ready to pull a good stunt. Two years ago around April Fools' Day they told listeners they had just received information about new legislation that would require pet owners to pay a tax, based on things such as how much the animal ate.
"The phones went nuts," Harding says.
The duo also makes personal appearances for the station, and the next one will be a summer kickoff party Saturday, June 21, from noon to 3 p.m. at Hagerstown Municipal Pool.
They enjoy meeting some of the regular callers that they've known only by name.
"They get the same response as we do," Harding says. " `You don't look like you sound.' "
