LA7VHF

LA7VHF is a very useful signal source for propagation studies on the 2 m band. The transmitter provides 55 W of RF power into a 10-element-yagi antenna. Since July 1997 the frequency is 144.451 MHz. The furthest observation was made in June 1992 by DB8KJ in Germany (~2300 km) through Sporadic-E-propagation. The high radiated power (500 W ERP) makes the LA7VHF beacon particularly attractive for monitoring Meteorscatter and Auroral-E propagation.

The keying sequence includes the callsign and the locator. For power saving reasons the locator is followed by a string of dots and not by a continuous carrier.
