Ham Radio Shack
Welcome to NE7X's Amateur Radio Station
Please Come-On-In
The NE7X ham radio shack is a 500 sq ft custom built room off the north side of the home QTH garage. It has it's own separate electrical sub-panel and HVAC heating/cool unit. The ham radio shack has two entrances, a private outside entrance (shown above) separate from the home QTH, and one entrance via the garage. Access to this outside entrance is located behind the RV gates. The ham radio shack being separated from the home by the garage, gives a sound buffer in the middle, allowing for 24 hour contesting without disrupting others inside the house.

This picture does not show very well, however there is 30 feet of storage shelving along the east wall (left) behind the rack cabinets. The racks act like a partition which isolate the storage shelving from the main radio room. There is a 25' long by 3' wide walk-way between the storage shelving and the rear of the racks. Beside providing access to the storage shelving, this walk-way also provides access to the rear of the racks for wiring and cabling maintenance. Entry to this area is left of the racks by the antenna wall field.
