East Yorkshire Repeater Group, a radio amateur group dedicated to providing repeater services including training to the East Yorkshire Region.

One of the useful features of the D-Star is the ability to link repeaters together into groups using the Reflector system. Using the UK Reflector (REF005A) all the users on all the D-Star repeaters in the UK are able to talk on one big network. However, the problem is that most repeaters are linked into this Reflector by default, and as a result it gets used to hop between neighbouring repeaters during our daily commute.

We have been recently offered the use of one of the high bandwidth Reflector slots that would allow us to link together all of our local repeaters (GB7HU, GB7RW, GB7YD and GB7HX) together into a regional network – this is common elsewhere with regional networks in the Midlands, Wales and Scotland.
Users within this group are able to Link and Unlink as before, but are encouraged to use the regional network instead of using REF005A during peak hours - by programming defaults into the local repeaters.
If you have D-Star but have not yet registered your callsign through an existing D-Star repeater you will not be able to use the features of D-Star Plus such as linking through the Internet.

GB7HU is now enabled for the registration of callsigns to use D-Star gateways worldwide. If you wish to register your callsign through GB7HU then please email andyg0vrmATgmail.com or cliveAThesh.co.uk (replace the AT with @) with your callsign, name, surname and one or more of the following:

  • Your address; it will be checked against the current Callbook so you must have a full entry and not a 'name and address witheld at licencee's request' entry.
  • Alternatively you can scan the first two sides of your licence or if you have the PDF from Ofcom then forward the pages with your details on.
  • Indicate that you have a current entry in QRZ.com

The purpose of this vetting procedure is to prevent misuse of the repeater going beyond its coverage area.


The D-Plus system is now fully working giving access to all other Internet linked D-Star repeaters around the world.

There was some difficulty with accessing the D-Star controller at Weedley from the gateway PC at my QTH in Anlaby that was traced to a problem with the 5.745GHz WLAN head unit. It was fixed with a firmware upgrade.

The Weedley end already had the firmware upgrade installed but the Anlaby end had been replaced (see earlier post) with a head unit that had not been updated.

Thanks are due to Darren Storer G7LWT who checked the bits of the system I can't see remotely from his QTH in Manchester.

GB7HU Joins the Worldwide D-Star Network!

After working into the small hours, Darren Storer (G7LWT) of the UK Interconnect Team has installed the Icom Gateway Software onto our Gateway PC. The system has been approved by the Trust Server Team in the US and our D-Star Repeater GB7HU has joined the Worldwide D-Star Network. The D-Plus system which allows the system to link into other D-Star Repeaters and Reflectors worldwide is currently being installed, and should be operational by the time you read this thread...

I will be creating the training material and the .ICF files for the Icom IC-E92D handheld and Icom IC-E2820 mobile over the next few days to enable everyone use the system to its full potential. 

Thanks go to Darren G7LWT for configuring the system in record time, and to Clive G3GJA for putting the wireless infrastructure in place to allow GB7HU to use his Internet connection from Anlaby at no additional cost to the group - something which is becoming an issue to the many D-Star repeaters around the UK.

The Group purchased two pairs of EnGenius EOC-5611P wireless bridging units after it was found that some loaned units were unsuitable for getting an Internet link to the site. The EnGenius units were supplied by local wireless LAN specialist Solwise Ltd. As detailed in an earlier post, one of the units was fitted to the EYRG tower on the 27th June.

WLAN unit

Prior to this I had been busy refurbishing my home telescopic mast and rotator system so that I could use it to mount the other end of the wireless LAN link. It had been out of use for several years and needed replacement of the stub mast, bearings stripping down, cleaning and re-greasing etc. After reassembling the mast, attaching the bridging unit and cranking it up to the full height of 14m the CAT 5 cable was plugged into the laptop and ... nothing!! Not even a trace of the Weedley end of the link

There were some weak 5GHz signals from and adjacent mast at Weedley used by the wireless broadband company Quickline so I knew that my end was working OK and because the unit is on the rotatable part of the mast I knew I'd got the 290deg heading correct. Over the next week I tried linking to Weedley from a couple of locations where I could park my car and see the Weedley towers using one of the spare units and was succesful.

On Sunday 3rd July I decided to look at the Weedley end from the ground and re-checked the reciprocal bearing of 110deg. Although not very accurate as I was sighting the angle from the ground, the bearing the antenna was pointing as measured on my compass looked more like 150deg. A call to Richard YTV and Lyndon resulted in a rapidly convened working party at 4pm. We lowered the mast, luffed it repositioned the bridging unit and raised it again within two hours.
News from the "dstarsoftware" yahoo group is a new version of DV Node for Windows has been released...

The DV Node for Windows (WinDV) allows you to create a D-Star hotspot using either the DV Node Adapter board or the DV Access Point Dongle. It is aimed at replacing both the DVAR Hotspot program written by Mark McGregor KB9KHM (http://w9arp.com/hotspot/), and the DVAP Tool software supplied with the DV Access Point dongle...

Configuration was very easy as can be seen - just download the executable from the Dutch Star website (https://www.dutch-star.eu/index.aspx) and it's up and running.

The software can connect to the D-STAR network using either the Dplus (used on the Reflectors, by the Icom repeater gateways, the DV Dongle and many DVAR HotSpot nodes) as well as the DExtra protocol and the XReflector systems - some further reading required!

There is support for the ircDDB network which speeds up the updating of the D-Star Database and also the ability to forward GPS position reports (from both the Node as well as from any RF users) onto the APRS network through the built-in APRS-IS module.

Who knows what's around the corner - perhaps a replacement for the Icom Gateway software running under Windows?

On the 26th June, which was probably the hottest day of the year to date, a working party from the East Yorkshire Repeater Group visited our site at Weedley to install the 5GHz wireless antenna on the mast...

The easy part is lowering the mast on the electrically operating winch, the hard work is luffing tower to gain access to the aerials at the top - the whole process taking about an hour. This provides an opportunity to do some of the less technical tasks, systemic weed killer applied liberally to the remaining vegetation!


Why does the autofocus concentrate on the leaf in the foreground and not the intended subject?

A couple of jubilee clips and some outdoor Cat 6 cable and the whole lot has to go up again...


Where have all the helpers gone ? To do the more technical work of configuring and testing the wireless link on site in preparation for installing the other end with the Internet...


The East Yorkshire Repeater Group welcomes all willing volunteers, especially on maintenance days when there are numerous tasks: Applying grease to the tower's cables (which invariably ends up on one's best t-shirt), antennas to check, fences to paint, etc. However this does provide a rare change to learn a little more about how repeaters actually work!
RadCom Preview (July 2011).
Following discussions at the last East Yorkshire Repeater Group committee meeting, we agreed to apply for a club callsign to be used for our training and emergency communications role. We were fortunate enough to have been granted the callsign M0GYR - whilst this was not our first, second or even third choice, it does represent what the group provides...

This isn't officially our new logo - it's just one I've drawn up to get us away from the one we "borrowed" many years ago from our the local council!

A common criticism of 70cms D-Star repeaters is that the input can be somewhat "deaf". This ofter results in a situation where you cannot always access it even though you can hear it on your radio - this is more apparent when using a hand held with low power and inefficient aerials.

The standard fix for this is to retrofit a 70cms preamplifier and a simple filter inside the ID-RP-4000V band module - the one recommended by the RSGB ETCC is the Kuhne Electronic MKU LNA 432 A is retrofitted inside most systems. In our case, this task is not easy with the output being only 1.6MHz away instead of the usual 9MHz and significantly more filtering is required.

For those interested in the details of the preamplifier - the specification is shown below...
