The 2m NP2X beacon is now operational from St.Croix in the US Virgin Islands and its primary purpose is to investigate the TEP (Trans-Equatorial Propagation) path to South America.
The beacon is on 144.291 MHz and sends its ID in CW. It runs 100-watts into a 15-element Yagi antenna. The beam heading is 170 degrees as the primary target area is Uruguay (CX), the south of Brazil (PY) and Argentina (LU).
The beam width of a 15-element is about 30 degrees i.e. +/-15 deg. The map above shows the direction for the main beam heading as well as the -3dB points. The photo below shows the antenna and the sea path to the coast of South America.
