June, 1998

The building VE6NHB shared at the Edmonton (Sherwood Park) CBC transmitter site was being demolished to accommodate new construction. This required removing equipment from the site until a new smaller building, that would be for VE6NHB only, was provided.

The equipment was relocated to my home (Barry - VE6SBS) for servicing and to have the two Harris radios, which had served as the UHF Hub repeater, replaced with a Motorola MSR2000 UHF repeater. After a week it became evident that the new building would not be available for several weeks so VE6NHB was set up and temporarily operated from my QTH. As we waited for the new building an equipment rack was located and the equipment was all installed in it. Now, when the new building was ready, the equipment rack simply needed to be moved to the repeater site, connected to the antenna feed line and plugged into an AC outlet to once again have VE6NHB operational at the site.

Boards bolted to the rack are for protection and will act as skids while rack is slid up the basement stairs on wooden rails which can be seen in background, lower left corner, of the next photo (to the right).
