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

Output power is 10Watt.  Horizontal Open Dipole antenna a brand of Italian Sirio factory with  a gain of 1,8dBd.  TRX direction is NNO en ZZW. Antenna is transmit horizontal up about 8 meters high above the ground, we use celf400 coax antenna cable from DDS.

Mode is CW A1A  Location is the city is Zevenbergen JO21HP

Zevenbergen is located in the South West part of the Netherlands close to the Belgium border.

 

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.

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:

VVV DE PI7BRG QTH JO21HP BEACON 10 WATT RPT TO PI7BRG AT YAHOO DOT NL


The installation of the beacon station is very simple.

 G4SWX  John  9-12-2011    519  JO02RF  226 The beacon is audible every day, even under very poor conditions – approx 519 but +/- 10dB of fading due to aircraft etc. The strength is comparable with PI7PRO and PI7HVN which are also audible all of the time. 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
PE1FOX Alex 17-09-2012   319 JO32JG   Het baken komt met een gemiddeld signaal van 319 door. Wanneer er wat kleine condities zijn hoor ik het baken al snel met een signaal van 529. Ik gebruik een 16 El Tonna op 14 meter hoogte met een Kenwood TS711
PE1ASH Renny 16-Jan-2017   559 JO22KF40OE 65 Ik beheers geen CW maar heb een tooltje gebouwd waarmee ik CW kan ontvangen. Ik ontvang het baken vrij hard met een S5 ongeveer. Keurige stabiele toon, want dat is belangrijk voor mijn CW tooltje. Mijn QRA locator is JO22KF40OE, dat is in Mijdrecht plm. 20 km onder Amsterdam. Mijn antenne is een 6 elem kruisyagi op 28 meter hoogte, maar omdat ik in een polder woon die 6 meter diep is , staat de antenne op plm22 meter boven zeeniveau.
