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

Now for the second big announcement to start the New Year with!

Barsley based amateur radio retailer LAMCO have announced on Facebook that they are sponsoring the installation of a Yaesu DR-1 xe Digital Fusion Repeater that will be used to replace the PRF10 currently in use by GB3HS at high Hunsley.

This will NOT affect current users of the GB3HS analogue service and the repeater will perform much as it does now but it will allow those users with Yaesu Fusion equipment to use a digital repeater. It will also support cross mode contacts.

There will not be an Internet connection as that functionality is still in development.

The Group will continue to support D-Star on GB7HU and no changes are planned for that service.

The announcement from LAMCO is reproduced below:

We are very proud to announce that we are sponsoring the supply of a brand new Yaesu System Fusion Repeater to The EAST Yorkshire Repeater Group which will eventually be operating on the Hull GB3HS on 145.650MHz.

The System Fusion Repeater will be active in early 2015 in time for the new Yaesu FT-991 and the Yaesu FT-2DR hand set....

There are two big announcements regarding GB3HS to start the New Year with! In this post the move.

Yesterday, GB3HS was moved from Cave Wold (Weedley Farm) to the commercial High Hunsley site, commencing operation at 1500 hrs.

So far the performance of the site has met expectations with much improved coverage towards York, Grimsby, Lincoln and Bridlington. There’s just over 17w going into the feeder so allowing for some loss in the feeder it’s close to the allowed 25w erp and that is putting a massive signal of -60dBm (224µV!!) into my receiver at home, some 12km away.

Viking Radio is putting -10dBm into the repeater's receiver port but there’s no sign of the mixing issue that caused us grief when we last used the other side of the farm in the 1990s. With a fixed antenna system there should be no degradation in high winds, which was just audible at Cave Wold.

GB3HS installed at its new site

We are using a pair of stacked wideband dipoles for transmit and a wideband dipole at the top of the mast for receive. There’s just over 40dB isolation between the two antennas at 145MHz which is more than enough with the 74dB notches in each leg provided by the cavities. We will now concentrate on getting another two cavities tested and tuned that will allow single antenna working. The attached photo shows the repeater in its new location.

My thanks to Andy G0VRM and Richard G4YTV who helped me move the repeater.

It looks as though the 5.7GHz wireless LAN link that provides an Internet connection to the Weedley radio site from my QTH has been fixed at last.

The link started dropping out but always seemed to recover from a reboot at the Weedley end. The dropouts became increasingly more frequent and the cause proved difficult to locate due to their intermittent nature and because the fault cleared as soon as you started to work on it. We also noticed that the head unit would not work on its original frequency and would only link some 200MHz lower.

A process of elimination has isolated cause to be the switched mode wall-wart power supply that feeds 24vdc to the power-over-Ethernet injector. This is the power source for the 5GHz wireless head unit. Having replaced that it was found that the link could be put back on its original channel, well away from all of the mush radiated from the numerous links used by the three wireless Internet companies operating in Hull.

It's now stayed up for a week so hopefully it will stay up. All that grief for a £4.70 power unit!

Things have moved on since I last posted. Some 23cm ATV repeaters have now been approved and following discussions with Noel G8GTZ we have today applied for a move to Weedley and a change of mode to DVB-S. The predicted coverage map is based on a 10w TX which is about as much as you can get out of the existing PA when using DVB-S before the regeneration of sidebands becomes unacceptable.

We have decided not to take up Phil's kind offer of the use of the Octon site for the following reasons:
1. There is only one active ATV operator near the site and even then it's doubtful whether he would a get line of site path because Octon is to far north of the edge of the hills above Driffield.
2. Octon is too far away from the population centres in the south of the county. This is the same issue that blights Aldbrough causing EY to give good coverage to tens of square miles of empty fields. ATV needs big signals to cope with the wide bandwidths and it's not unusual to need in excess of 20 microvolts to get a usable analogue transmission. That's not compatible with a repeater that's more than twenty miles away.
3. The high ground of the Wolds to the south restricts coverage in that direction protecting the radar at Claxby and reducing the signal from Claxby getting into the receiver. There is no geographical screening to the south at Octon (unless you're in Driffield!) which would not help persuading the CAA to approve the move.
4. We want to use the existing Internet connection at Weedley to stream the receiver's output onto batc.tv

Noel has told us not to hold our breath as it's going to take some time. However, if all goes to plan ATV is set for a big boost in the area with DVB-S inputs on 70cm and 23cm, streaming and a much better service area. We also plan to link in the 3cm co-sited ATV repeater...
This weekend the GB7HU D-Star repeater in Hull has changed frequency to 439.4875 MHz and joined the other digital repeaters.

For the last few years the repeater has "borrowed" the frequency pair from it's little-used analogue repeater GB3HU, and discussions are now underway to re-instate it. The frequency change has allowed the group to install a DB6NT UHF pre-amplifier and vastly improve the receiver sensitivity and move to single antenna system - Thanks to Clive G3GJA for his hard work!.
Over the next month or so GB7HU will QSY away from the analogue allocation borrowed from GB3HU on 433.075 MHz to join the other Digital Voice Repeaters on 439.4875 MHz.

Seasons greetings and best 73s to all at EYRG
Dear Repeater Group Members

The RSGB and RAEN have agreed between themselves that they don’t want two amateur radio emergency organizations in East Yorkshire and the affiliation that our sub group has with the RSGB is not going to be renewed. A meeting has been called for the 13th of November to form a new single emergency comms group for the area under the banner of North Humberside Raynet.

Your Committee has decided that the repeater group should have a meeting before that date to listen to the Repeater Group’s members views about any future involvement with emergency comms so that we can formulate plans for the services we provide.

This is not a formal meeting at which a vote will be taken but we do want to hear from members what they think that the future direction of the group should be. This covers all areas of the services offered by the group including ATV, Analogue and D-Star repeaters and not just emergency comms. We would also like to hear of anything that members feel the Group should be involved in that we don’t currently do.

Please do come on the Thursday the 7th November at 7.30pm to the Hull Club’s meeting room in Goathland Close off Walton Street and let us know what you want from your repeater group.

The MB6EY Gateway will soon be operational the QTH of Tony G4SJI at Withernsea in East Yorkshire. The gateway is currently running on a Raspberry Pi computer using a DV-RPTR Version 1 board imported from Canada.

Here it is on test from my home QTH using my FT-847 into a dummy load.

Recently I have noticed a few people promoting DMR as the DStar replacement. So I have been looking into DMR a bit. Some of you may have read about Mototrbo which is Motorola's marking name for the DMR technology.

I intend to do a more in-depth comparison here between the various digital technologies. Not just DStar versus DMR, but also look at whatever Yaesu is coming out with, APCO25 and Nexedge/NXDN.

So I signed up on Yahoo Groups with a few of the DMR and Mototrbo groups. Via radio reference website, there even is a link to listen to one of the DMR networks/repeaters.

One of the first questions I asked on the groups, "can you build you own DMR/Mototrbo repeaters?" In other words, is it practical?

The answer I got was basically "no" that it is not practical and they way to get a repeater is to "get some of my friends together to share the cost." Also, not practical.

Now with DStar you can build a repeater yourself very easily. You need two transceivers with packet ports capable of supporting 9600 baud packet, a hotspot board and a computer. So here is what it cost to build a home-brew DStar repeater that a couple of folks in a local radio club are considering building.

Two single band Alinco radios. $279 each. Moencomm GMSK Node Adapter (hotspot board) at $120 and a computer, in this case a Raspberry Pi with Ethernet Adapter ($35 for the RPi and $30 for the Ethernet adapter. Total cost of the DStar repeater is $743 using all new equipment except for the duplexers and antenna which the club already has for the old UHF FM repeater days.

DMR well for a new repeater, since there are not a lot of used repeaters, about $3,000.

The other issue I see as a problem is with DMR each radio has an ID that has to be registered and is tied to the callsign of the user. This appears to be a real issue with sharing equipment and callsign routing, that is not an issue with DStar.

Also DMR programming is very complex. Mainly because DMR was meant for the commercial...
