From Mike Williams:

WDUD was the 50 Watt [AM] transmitter built by Randy Hudson that we used in several applications including at Radford. It was one of the many things that nearly electrocuted me.

From John Lyles:

Randy Hudson built this nice 50 Watt transmitter that used 807s for the RF stage, modulated with a pair of 7591 hi-fi tubes. It had a VFO, so you could vary the frequency around 640 KHz, to try and set a zero beat note with the Akron, Ohio station at night. Hud’s transmitter fell into disrepair when no one paid attention and the Radford RF couplers were in a terrible state, with some coaxes in flooded steam tunnels. The Radford tunnels were horrible compared to VPI's. The WUVT mole squad of engineers loved to work at Radford, as it was mostly females, and they often used the rooftop of their high rise dorm for tanning. Luckily, one of our coupling boxes was in a closet upstairs. We did a renovation there, and I almost lost a finger on one of the steel gratings leading under a sidewalk into the tunnels. AM-64 was back on in Radford.
