I worked there, too (circa '88-92). They were The Hot FM, too, long before those other guys.
We had a pic of a DLX sticker on an East German warning (Achtung!) sign from before the wall came down. Priceless!
There was a Hot FM decal somewhere around in there too. I thought it was hilarious given our competition was the Hot FM, and back then, they truly were competition (with twice the shares we had at that!)
Beyond just the 80s, that building was so full of history it was amazing. I spent hours just looking around.
Anyone driven by there recently? The Pirate Radio folks have cleaned up the lawn, removed the letters from the building, and given it a fresh coat of paint. Place actually looks quite nice now. They don't even have a studio presence there and yet they care more about that building than NextMedia did when it was their main office!
