GB3WE VHF repeater now an ALLstar analogue FM repeater

On Sunday 10th December 2017 we had a major failure on our transmit mast, which has caused us to shut down all five of our repeaters.
We need to purchase a replacement mast as well as new guy wires ASAP.

If you can help with a donation so that we can put our repeaters back on air then please use the PayPal donate button on this site or use the contact form so that you can use bank transfer or meet up with us.
Any amount will help!

GB3WE VHF repeater now an ALLstar analogue FM repeater!

You can now talk World wide via the ALLstar network using your VHF FM radio.

We are connected to HUBNet which is a very busy network.

HUBNet

M0HOY HUBNet Monitor

ALLstar Network

The repeater is controlled by a tiny raspberry pi 3. This handles the ALLstar connectivity as well as the courtesy tones and logic.

You listen on 145.6875MHz
Use a -600 KHz Split
94.8Hz CTCSS
You transmit on 145.0875MHz

Our UHF FM repeater GB3WB has the same raspberry pi 3 ALLstar system fitted.

You listen on 433.300MHz
94.8Hz CTCSS
+1.6MHz Split
You transmit on 434.900MHz

At the end of each transmission or ‘over’ the analogue repeaters will send one of three CW (morse) letters.

They will send an ‘L’ (.-..) if the last user was a local RF user and the repeater is connected to the ALLstar network.

The repeaters will send an ‘I’ (..) if the last signal was originating from the Internet.

The repeaters will send a ‘U’ (..-) if they are not connected to the ALLstar network and the last user must have been a local RF user.

GB3WB automatically disconnects from ALLstar at 21:00 until 22:30 every night to allow the repeater to be used for a regular net which is run from the Cardiff area and this net has become a great part of GB3WB. During this time GB3WE is still connected to the ALLstar network, so please use this repeater for ALLstar contacts.

When ever using the ALLstar network please always leave a four second pause between transmissions as this allows the nodes and repeaters to reset. This four second gap also allows others to break into the conversation.

Our two Allstar repeaters are connected to the HUBNet UK network.

Please get in touch using our contact form if you think that any of our 5 repeaters are not working.

This is the Weston repeater groups cabinet July 2016, only one of the Yaesu repeaters is being used for fusion! One is FM only and two are used for MMDVM:

Decibel Products 4 channel hybrid combiner

A Decibel Products 4 channel hybrid combiner is now used to combine all 4 of our UHF repeaters transmitters so only a single antenna is required!

This is a very expensive piece of equipment which we had to import from the USA.

It was well worth the expense as it works so well.

Motorola MSF5000 TLE2522 UHF Amplifiers now used on our repeaters

Motorola MSF5000 TLE2522 UHF Amplifiers are now used on our repeaters, because of the massive losses in our 4 channel Decibel Products hybrid combiner which we use to allow all of our 4 UHF repeater to use the same antenna.

In total our Decibel Products hybrid combiner and two TX notch filters put about 10dB of loss into our transmit path.

To get 1w out we need to run 10w and to get 10w out we need to run 100w!

That is why we need big reliable amplifiers which require only 3w of drive to produce 100w.
All of our repeaters have been reprogrammed to run only 3w now which means their PA’s are just ticking over and not even getting warm!

We have also fitted Big 50 Amp ACS758 current sensors to our amplifiers so that our Arduino Mega web server can measure and display the amplifiers performance on a web page.

We have also attached a 7 segment voltmeter display to the green wire in the 6w molex socket so we can see the TX output power forward voltage. This forward voltage is around 8.8v  when the PA is running 100w.
The red wire in the socket is connected to a 100k thermistor mounted on the heatsink to allow you to measure the PA’s temperature. Measure between the red wire and the black wire which is ground.
The brown wire is connected to the 100k thermistor mounted on the dummy load of the circulator.

MMDVM GB7WB

Brandmeister DMR on GB7WB

GB7WB is our DMR repeater which is connected to the Brandmeister network.

We are using a Yaesu DR-1X repeater with an MMDVM KI6ZUM board and TCXO on an Arduino Due plugged into the rear 15w HD connector of the DR-1X.
The MMDVM is run by a tiny Raspberry Pi 3 computer with the KB5RAB image installed.

You can now operate through GB7WB on 439.4875 MHz with a -9 MHz shift using DMR.

On DMR use timeslot 2, talkgroup 9 and colour-code 1 to talk to the World via the brandmeister network.
The local chat channel is on TimeSlot 1, TalkGroup 235145, colour-code 1.
