NE7X - Phoenix Arizona USA
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.
