AS OF JUNE 2010 THIS BEACON WAS SHUT DOWN & AT PRESENT THERE ARE NO PLANS TO RE-ACTIVATE IT !
My beacon, installed in February of 2006, is presently operating 24/7 on 28.2485 Mhz transmitting 500mw into a 1/4 wave GP vertical antenna. Location is in San Antonio, Texas - Grid: EL09qn.
Any comments you wish to leave will be greatly appreciated. Thank you for taking the time to make this report.
Scroll down for some pictures and information about the beacon.
The beacon controller is contained in a small plastic case.
The board on the right is the beacon controller; a FREAKIN' BEACON by Expanded Spectrum Systems. It controls all the functions of the main beacon transmitter. The other board is the original beacon transmitter which is now used as a backup.
The beacon transmitter.
The beacon transmitter is a converted RadioShack 27 Mhz pager transmitter. After changing the crystal it was retuned and set to output 1/2 watt. Heat sinks were added as well as a small fan to keep things cool.
The beacon antenna is a 1/4 wave ground plane vertical on a 15 foot mast.
