Description:The 300 Foot Telescope could not be moved over the full 60 degree range of zenith angle allowed by the drive system without the rim hitting the ground. Frank Drake suggested digging a ditch on the south side to lower the elevation limit. Excavations hit bedrock just six feet below the surface. Perhaps some dynamite? Many were anxious that a blast might damage the new antenna. Rocks and debris flew, one rock put a foot-wide hole in the telescope surface, but there was no other damage, and the southern declination limit was successfully extended to minus 19 degrees.

Description:Jet engine in the shop, January 1963. From left: unidentified, Clifford Barkley, Paul Devlin. The exhaust from the engine was directed upward towards the underside of the 300 foot dish to melt snow and ice from the dish surface, It was used during the winters of 1964-65 and 1965-66, but then abandoned because the engines required constant maintenance, spare parts were difficult to obtain, it was costly to run - and it was extremely loud.
