After many
years of PA0EHG's superb beacon service from Holland, we have
to sadly announce that these most useful beacons have had to be
removed from their location at Schipol Airport. The UK Microwave
Group tried to he;lp retain the beacons by wirint to the relevant
Dutch Authorities. Please visit PA0EHG's website more more of
the sad details. If you can help relocate thiese beacons within
a realistic travelling distance for Hans, then please contact
him by email.Here's his email giving the bad news...

With much regret
I must inform you that all the microwave beacons(1.2Ghz up to
47GHz)are now off . I did show your (UKuG) letter to the management
but it did not help. With help of some colleague amateurs I am
trying to find a new location and get the beacons on air again.
Thanks very much for your help and support.
Today has been a very bad day for me.

I have recived today the beacon from DB6NT and it is now being
tested at JO28UX.
I am still waiting for the 1 Watt PA to arrive.
The final QTH is JO28UO and this is 150m over sea level, and a
seapath to UK, OZ, PA, F and DL.
ERP is approx 50 watt, transmitting at a 2 directions:
1: s.w. with homemade 13 dB horn, very low el. / but wide
az. angle.
2: North with high gain 17dB horn.
Keying is by a WW2R module with fsk shift of 10kHz.
I will get back with more info when the beacon is in normal operation.

Subject: GB3ZME beacon 5.7GHz QRV
Hello Microwavers...
GB3ZME beacon
on 5760.910MHz now back on after 2 month break.
The PA is now
15 watts, fed to 8+8 slotted waveguide via 25' of LDF550.
We are trying
a different approach to crystal stability, based around DB6NT's
current temperature control module. I wish he made a 60 deg version
available! The 40 deg standard can well be exceeded on a hot summer's
day in a stuffy loft area, where two of the 'ZME microwave beacons
reside.
As I can't monitor
this one at home, would appreciate reports, for both normal "flat
conditions" and enhanced propagation. (email me at: ukv@ukv.me.uk)
Acknowledgements

Note: All
three GB3ZME beacons are now fully operational, viz:-
3400.910MHz
(HF in warm weather) 15 watts, Ionica antenna, 120degrees beamwidth,
centred approx. SE.
5760.910MHz 15 watts, 8/8 slot. Omni
24048.910MHz 1 watt, omni 40 slot. Omni. It may drift many

24GHz
beacon from Schiphol
From: Hans v Alphen
[pa0ehg@amsat.org]
Sent: 01 March 2004
This is to inform you that the 24GHz beacon at Schiphol is now
again QRV and on the of 24048.200 MHz.
Power output is 150
mW into a 24cm dish beamed to G3LQR and 800mW into an omni
antenna. Both outputs have the same frequency.
Further info, including pictures, is published on my
website .
The beacon is in fact almost completely new, with an OCXO designed
by G8ACE and further a new multiplier from 12 to 24 GHz giving
150 mW. Then a directional coupler of 20 dB followed by a amplifier
with 800 mW.
I would welcome any RX reports.

47GHz
beacon operational from Bell Hill
From: Talbot Andrew
[ACTALBOT@mail.dstl.gov.uk]
Sent: 23 February 2004
On Thursday 19 February
2004, a 47GHz personal beacon running the callsign G8BKE/P began
operating from the site of the GB3SC# complex on Bell Hill in
Dorset, IO80UU59.
It is a self contained
beacon constructed by G8ACE, generating around 10mW of RF to a
20dB horn, the whole unit being built into a sealed box mounted
at the top of the beacon mast. The frequency source is derived
from a stable locked oscillator and should remain accurate to
within a few hundred Hz of its nominal operating frequency of
47088.905 MHz. The antenna is pointed on a bearing of around 80
degrees from the site - it is targetted at G8ACE's Winchester
QTH and surrounding high spots such as Cheesefoot Head, at 75km.
Antenna beamwidth is in the region of 20 degrees
Chris G8BKE has access
to the secure remote control link for the complex to comply with
turn off requirements.
This brings the total
of beacons operating from Bell Hill to seven. Apart from the five
forming the GB3SC# complex, a low power personal beacon signing
G4JNT/P on 70.031MHz has been running for 18 months and now G8BKE/P.
Is this a record ? There is now room for only one more unit before
the
remote turn off capacity is saturated.

GB3SC#
series beacons: November 2003 update
From: Andy talbot
[G4JNT@THERSGB.NET]
Sent: 07 November 2003
The two highest frequency
beacons of the South Coast microwave beacon complex, GB3SCX
on 10GHz and GB3SCK on 24GHz, are now operational again
after a major rebuild of both units.
Both have had their output
power increased, raising them by at least 10dB over their previous
nominal values. GB3SCK has retuned to transmit on 24048.905MHz
in order to comply with the new 24GHz bandplan which will come
into force at the beginning of 2004.
GB3SCC on 5760.905MHz
has had its keying duty cycle adjusted - it now transmits callsign
and location details, followed by plain carrier for a total of
45 seconds, then stops transmitting for 15 seconds to assist
thermal management. This keying sequence will be maintained over
the
winter period and will be reviewed when warmer weather returns
in the spring
As an precautionary measure,
the beacon complex will remain operating with its mast at reduced
height for a while, until the continued reliable
operation of the rebuilt units is assured. This reduced height
should only
affect propagation in a north west / south east direction due
to slight shading from local trees.
Reception reports
should be sent to John Fell, G0API QTHR.
Amateur microwaves are
still going strong in spite of RSGB's attempt to stifle all representation
of our use of frequencies above 1.3GHz , with their abolition
of the Microwave Committee.

NEWS
FROM MURRAY, G6JYB ON THE GB3CMS 10GHz BEACON
November
2003
Your web page entry for
the Essex 10GHz Beacon is currently:
10368.896 GB3CMS JO01HR 25w ERP slot OMNI 07/97 QRV
If only it were 25W!
It is, and always has
been 30mW source power into a
10dB Omni slotted waveguide-16 antenna
since it was re-sited in July 1997
It's located at the qth
of G1EUC, just down the road on
Danbury Hill from G4EAT that great DXer
An application to raise its height and power made in May 1999
was blocked by the primary user (esp because we are inside
the Charing Cross radius).We did not press this too hard lest we
get an order to shutdown altogether!
Details and photos are
on the Essex
Repeater Group website www.essexrepeatergroup.org.uk
Then click links for
Equipment (or Gallery for photos),
and choose GB3CMS

Niman G6JYB
(Thanks Murray ..if
you check the beacon list now you'll
see it's been corrected)

GB3SC~
Beacon Progress update
From: Andy Talbot
[G4JNT@THERSGB.NET]
Sent: 12 September 2003
On Friday Sept 12 , GB3SCS on Bell Hill, Loc IO80UU58, was returned
to service. The multiplier drift problems with temperature appear
to have been solved by changing the L/C ratio on one of the intermediate
filter stages to give a lower Q, wider bandwidth design. Its frequency,
when I measured it this afternoon, was 2320.902MHz +/- 1kHz.
The 24GHz beacon GB3SCK
has now been taken off air for retuning to 24048.900MHz, by Chris
G8BKE. Hopefully this will be a straightforward task.
GB3SCX is still undergoing
its major rebuild. I am looking at the best way to achieve a high
stability phase locked performance without trying to lock an overtone
crystal oscillator. This is undesirable as it results in an inherent
low loop bandwidth and so gives potential for frequency wandering
around its nominal freqeuncy - not something that is desirable
for a narrow band beacon designed for SSB reception!
Metalwork is being constructed to allow reliable heatsinking of
the new PA in the head unit, which dissipates over 20 Watts, in
all weather conditions. Since the head unit can be exposed to
outside temperatures of 38 deg with the sun shining directly on
it (if the weather of August is repeated) we need to make a good
job here.
No decision has been
taken on whether the 45s ON / 45s OFF switching cycle of GB3SCC
on 5.76GHz can be changed. During the winter period it could probably
be raised to a higher duty cycle, but with no spare PA to repair
the head unit if it does go pop, I'm reluctant to do so. All offers
of 5.76GHz PA modules gratefully received! As I can't continuously
monitor this beacon from home, accurate frequency measurement
is not possible at this stage.
GB3SCF, remains on FSK
keying with its callsign-only ident. This beacon is so reliable
and just sits there operating, that I feel it is tempting something
or other to dive inside and change anything for the sake of it,
much as I would like to convert to on-off keying and replace the
keyer with one that can be reprogrammed on site, as in all the
rest of the beacons. Frequency as measured a couple of days ago
was 3400.905MHz +/- 1kHz
All antennas are operating
at reduced height as reported last time. The mast will only be
wound back up when both the two high frequency beacon rebuilds
are completed
And the the sixth beacon
on site - G4JNT/P on 70.31MHz with 0.2W EDRP is a useful frequency
standard and tuning signal for several locals building transverters
for this band. Accuracy is maintained to within a couple of Hz
by using a DDS to derive its carrier from a 10MHz ovenned oscillator.
Data is transmitted as FSK, derived by reprogramming the DDS for
mark and space frequencies, and is currently set at exactly 85Hz
shift. The transmitted data consists of beacon shack telemetry,
transmitted using 1s dot period slow CW (known as QRSS to the
LF community) to indicate AC mains voltage and current, DC battery
voltage, shack temperature and the status of two switches. The
data is repeated in fast CW followed by callsign and locator ident
before returning to slow CW mode.
