The Irish 4m beacon EI4RF has now been upgraded and is now transmitting on 70.013 MHz. It was previously operating on 70.130 MHz due to the limits of the older Irish 4m band.
It is still located to the south of Dublin in the locator square IO63VE.
It is running 25-watts into a 3-element Yagi pointing east (90 degrees). The map above shows the beam heading with the -3dB (half power) headings as well.
