PI7BRG VHF BEACON QTH ZEVENBERGEN SOUTH WEST PART OF THE NETHERLANDS
Welcome to the webpage of the beacon station PI7BRG 2M (Freq 144.4310MHz)
 
Long distance radio propagation, intense tropospheric inversion layers may result in the ducting of radio waves which enables long distance radio propagation in VHF, UHF and SHF too.
The beacon PI7BRG is a troposperic radio propagation beacon, whose purpose is the investigation of the propagation of radio signals.
The propagation type is abbreviated to two characters:
TR=Tropo, RS=Rain scatter, AS=Aircraft scatter, SS=Snow scatter, MS=Meteor scatter, ES=Sporadic 'E' (VHF), AU=Auroral (VHF/UHF), AE=Auroral 'E' (VHF),TEP=Transequatorial propagation (VHF), F2=via F2 layer (VHF).
 
 
The QTH Zevenbergen is close to the sea, about 50KM locator JO21HP and I'm running 10W from a Kenwood TR-751E.  
   
The PI7BRG beacon has been on the air sinds 20 December 2009

latitude and longitude of Beacon  51° 38' 32.34"N  4° 36' 54.66" E

 

The beacon is now full operational and working 24 hours a day and 7 day's a week!

 

I'd like to thank OZ2M for his technical assistance with the keyer, and for all of the stations that have reported hearing the beacon and contributed to the study of propagation on 144 MHz. Please continue sending those reception reports!  See you on the band.

 

See below the build of the beacon station.

 
The test with the Kenwood TR-751E was in the end of January 2010 finish, until that time i was using the Yaesu FT-857D
First we tested the beacon Keyer of OZ2M, this was great working. A simple but very effective smart keyer. How simple is this keyer? Just two ICs - a tiny 5V regulator, and a small micro-controller. There are a few transistors used to switch and control the rig and create the RS232 interface used to program the Keyer and provide telemetry. Other than that, just a few resistors, capacitors, connectors and a cheap crystal. Will it long reliable working it must be very simple!
Testing of the beacon station. The message the beacon keyer transmitting is:

The installation of the beacon station is very simple.

However all three are far weaker than DM0DUB or ON0VHF which are both around 569 +/- 15dB.      QTH 41m ASL. Station: 2 X 17 element 4.4WL antennas @ 15m agl. Masthead preamp 0.5dB NF and TS2000 RX
