About This Report
The data in this report is generated by a QRP Labs Ultimate3S WSPR beacon operating from the GCARC clubhouse in Mullica Hill, NJ (grid FM29jr). The transmitter runs 100 milliwatts into an end-fed wire antenna approximately 65 feet long and 15 feet above ground, transmitting sequentially on the 40, 30, 20, 15, and 10 meter amateur bands. By keeping the transmitter location, antenna, output power, and transmission schedule fixed, this project holds the non-propagation variables constant — allowing the results to reflect propagation conditions alone rather than differences in station location, configuration, and equipment. The charts and globe below show which parts of the country and world are receiving W2MMD's signal on each band and at what times of day, giving GCARC members practical guidance for identifying the best bands and times to use when trying to reach stations in various regions.
