The information on this page is edited on : 23-04-17 All PI7EHG beacons are QRT After more than 20 years of beacon keeping and 15 years of microwave beacon on top of the ATC tower at Schiphol airport all beacons are QRT
My first beacon was QRV from Eindhoven around 1980, almost on top of the tower close to the Evoluon transmitting with 1.5 Watt into an 7 dB omni antenna on 1296.875 MHz.
In 1980 I
build a 10 GHz beacon when I was working at the Technical university of
Eindhoven. Some years
later this was modified with an PA to 1 Watt output,
When I started living in Enschede I setup a 10
GHz beacon PA0EHG in front of my window at the 9th floor of the building where I
lived.
When I started my QRL at Schiphol I setup my 10
GHz beacon on top of the ATC tower first on 10 GHz. These beacons have been operational for a period of about 15 years
After having to give up the location at Schiphol
ATC tower I tried to find a new location, Old info From 16-1-2008 the 10 GHz beacon is QRV from my home site I made a special antenna mast for the beacon on the back of my garden. Its a 9 mtr mast and the beacon antenna is at 10 mtr. Please send me your RX report because I need to know if my QTH is usable for all the beacons Take off is very fine in all directions so for tropo and rain scatter the location should be OK. The beacon is inside a barn and the antenna is fed using a waveguide of 14 mtrs long giving a attenuation of only 1.4 dB Because of the new rules for unmanned beacons in the Netherlands the beacon is remote controlled. Further detail will follow on this page. Details of the beacon: Antenna Omni antenna at 10 mtr Output power 50 W ERP Freq last measured: 10368.180 MHz Locator JO22HC Please send me your RX report.
--------------------------------------------------------------------------------------------------------------------- Old info Beacons at Schiphol have been
QRV for 15 years, Help me to find a new location for the beacons: I am looking for a new location for the beacons, what I need is a location preferably
high above the surrounding area, more than 50 mtrs ASL. I need full approval to go to the
site for maintaining and repairs if needed. For the different beacons I need to have a
mounting place for the different antenna's and a place for power supplies and oscillators.
The place for the antenna's should be preferably free of regions where people come because
of the high microwave field strenght. I need a main power supply connection and
possibilities to connect to lightning protection. Anyone who could help me in finding a new location please contact me for furtehr information.
Old information off the beacons. 3 cm beacon upgraded to 75 W ERP from Omni antenna, frequency 10368.200 MHz 24 GHz beacon QRV from 1-3-2004 with new frequency and new setup on 24048.200 MHz 47 GHz beacon QRV from 15-7-2004 on 47088.888 MHz 9 cm beacon QRV with 9 dB more power, frequency 3400.015 MHz New beacon on 13 cm QRV from
28-2-2001
9 cm PI7SHF en 6 cm PI7EHG beacon
Frequency's measured on 4-10-2000 by PAoEZ,
3 cm PI7EHG en 1.2 cm PI7EHG beacon 10 GHz beacon upgraded, 16 dB more output power, frequency changed to 10368.200 MHz
47 GHz beacon After many e-mails with John, G8ACE about his fet multiplier for 47 GHz and mentioning that I wanted to use such a multiplier for a beacon for Schiphol John offered me a beacon setup on loan basis to see how the multiplier would behave. John made me a nice system which I only had
to put in a box. The beacon will be changed to a own beacon by the end of the year, I hope with help of John.
