History and old news....


Close Down of GB3BK

Unfortunately TVRG have to announce that GB3BK, the Reading 70cm repeater on RB11 has closed down indefinitely. This happened at around 18.30 on Friday 2nd July.

GB3BK was sited in Woodley to the east of Reading. Originally it was anticipated that the mast, which is on the site of an old, now disused, police station would be retained and continue in use when the site was redeveloped.

However, the mast has to go as re-development is about to begin and we were asked to remove our equipment.

It's not as had as it might have been as one of the other TVRG 70cm repeaters GB3BN covers Reading reasonably well, certainly for mobiles. What is going to be missed is the excellent hand-portable coverage BK provided.

At the moment there is moratorium on licensing of further 70cm repeaters so we are not in a position to re-apply, even if we had another site. A "site change" is regarded as being a new licence application. We will keep our ears to the ground and see if there is any likelihood of a change in policy but this is unlikely in the near future.

So "Goodbye BK" - which first came into service in 1977

GB3BN antenna fault...

@ April 6, 2001

On the morning of April 3rd the usual morning crowd noticed that all was not well with the repeater It was observed that both the uplink and downlink were approximately 20dB down on usual and following a visit to site by Paul (G4HLF) an antenna/feeder fault was suspected.

Click to view full size imageA replacement antenna was acquired and on Friday 6th April a rigger attended site and replaced the Diamond X30 collinear with a commercial Skymast S.M4 four stack dipole array (see picture >>)

Click to view full size imageDespite the weather on the day the rigger was able to complete the work in around 3 hours. In addition to the antenna new ironwork had to be installed to allow for the bracing of the four stack at both top and bottom. GB3BN was off the air from 10:30 to 13:30.

Click to view full size imageThe Skymast S.M4 is at the same location and height on the tower as the previous antenna. Initial reports suggest that performance is slightly improved on the previous installation.

GB3BK moves home

@ Jun 1, 2002

GB3BK moved home on 1st June 2002 and was switched on at approximately 11:00am. BK is now located at Woodley, Reading and the new sites provides excellent coverage in Reading town centre and surrounding area's.

Click here to see more pictures of the BK moveChris (G4CCC) can be seen "humping" the cabinet into its new home. Previously BK was located at Aldermaston apparently down a mine shaft providing little coverage anywhere !

Click here to see more pictures of the BK moveBaz (G8DOR) switches on GB3BK from the new location Also worth noting is the brickwork in the background. Ian G8NXJ was entirely responsible on a previous visit.

GB3BN Site tests completed

@ December 10, 2000

On Friday 8th December myself, Baz (G8DOR) and Chris (G4CCC) spent a few hours testing GB3BN from it new location at Coppid Beech. Testing was carried out with BN in its final configuration using the Key Radio KF450 basestation, Procom duplxer and Diamond X30 dualband collinear.Click to view full size image

The antenna had been installed for us the previous week and is located 52m up the tower on the West side to restrict coverage towards London.

First impressions? Well it all looks very good so far. Baz was pleasantly surprised at how "clean" the site was (RF) and we heard no signs of any unwanted signals on the input. No sign was seen of any reflected power from the antenna and no desense was noticed when the TX was keyed. More importantly no problems were reported by other site sharers.

Limited time was available for coverage testing but we certainly had a substantial numbers of reports which were all very encouraging.

GB3BK To move to Reading

@ Feb 9, 2002

The Reading UHF repeater GB3BK currently located near Aldermaston (see this link for details) should be moving back to Reading in the Summer... all been well.

Tests have been completed from the new location (Old Woodley Police Station) and results were promising with good coverage been provided to Reading town canter. The application is now with the RMC/RA waiting for approval which will hopefully be granted over the next few months (See the RMC website for latest)

Steve (G4YFB) gets to work on the door covering himself (it would seem) in the majority of the wood shavings.

GB3BN Linking via ilink

@ Sept 29, 2001

A few of you have recently asked if BN is still Internet linked so I thought it time I explained the situation.

GB3BN will shortly be linking using a new application developed by Graeme M0CSH. This will provide a vastly superior interface and dedicated servers as well as additional security.

You can download the software and use it now to link to other repeaters, the application is small (less then 300K) and can be downloaded from http://www.aacnet.net/

GB3BN Internet Linking

@ May 04, 2001

Internet linking has begun on GB3BN the Bracknell UHF repeater during the evenings and weekends. The link will be active on an occasional basis and so far the response has been very favourable. The Internet gateway is G4HLF/1 and is operated by Paul (G4HLF)

At the moment BN is using Iphone to link to the Internet via an ISDN connection, In the future we will be looking at other options and technologies. For further information on Internet Linking visit Ian Abels (G3ZHI) page at www.qsl.net/g3zhi

TVRG assist with GB3HZ

@ February 25, 2001

Baz (G8DOR) recently visited GB3HZ to supply and fit a replacement PA for the Key Radio KF450 basestation. GB3HZ had been running at low power with a temporary PA for over a year, Baz's repair allowed the HZ to return to its normal power level.

On site on the day to meet Baz and arrange access were Peter Hicks (G4KCX) and HZ's NOV holder Iain Phillips (G0RDI). TVRG were thanked for the donation of the PA and the repair work.

Further information on HZ can be found at http://www.gb3hz.org/

Roger Jones, G3YMK

@ February 21, 2001

It is with deep sadness that we have been informed that Roger has become a silent key following a recent illness.

There are several references to Roger on this website for his outstanding contribution and enthusiasm that we experienced during the relocation of GB3BN. During this time we were fortunate to have the pleasure to meet Roger on several occasion. Roger was to be present at the "switch on" of BN but due to his illness at the time was unable to attend.

Roger will be sadly missed.

Our thoughts at this time are with Roger's family.
