GB7SE has been running now for over a week and so far has been working well. We wanted to bring you a few updates which have happened over the last week. A number of user activated talk groups have been added to ensure everyone can still take part in the weekly monday night net and speak to people attending the Dayton Hamfest. More details below on what User Activated is.
User Activated Group
The core DMR-MARC team has introduced a number of UA (user activated) talk groups. The purpose of these groups is to better manage the traffic across the worldwide repeater network. As you may be aware it is a requirement for all DMR-MARC linked repeaters worldwide to carry Talk Group 1. Talk group 1 is a worldwide talk group and when a user uses this talk group it will transmit across all the repeaters. For this reason it is best practice to limit the QSO on this talk group and had been practice to then QSY to talk group 13. Again this talk group is added to many English speaking repeaters and due to increases in traffic another solution was looked for. This is where user activated groups come in.
Repeaters carrying these talk groups do not transmit them in the same way as TG 1 or TG14. The “User activated” part means that the user has to initiate a call to the talk group and at this point the repeater they are accessing via will link to the talk group. Therefore only those repeaters which have been linked by a user locally will carry the traffic. There is a 5 minute time out, at which point it reverts back to normal passing traffic from the usual Slot 1 talk groups.
The suggested best practice now would be to initiate a CQ call on TG 1, and then QSY to TG 113 or TG 123.
In addition to TG113 and TG123, GB7SE will also be carrying TG119 and TG129. These new talk groups are again worldwide but are specifically for any language. These were commissioned for the forthcoming Dayton Hamfest. So to ensure everyone has access to these we have added them to Slot 1.

Managed to receive this image from the ISS on the 21:32 pass which was almost directly overhead.
The previous pass did not bear any SSTV Transmissions and a quick check on the APRS freq of 145.825 confirmed that the iss was transmitting APRS.
This was quite a good pass with just a bit of noise towards then end of the pass and i was able to get all of the transmission a few seconds before the footprint was out of range.
The Chance of going on a one night cruise does not come around to often, but it does mean a night to get together with some family members for a drink or two (and Im thinking play radio.)
The XYL was not overly impressed so I tucked away my Yaesu FT60 and thought yep I`m going to go marine mobile.
Now as we all know THE 2MTR AND 70CM bands are not overly active on any Friday afternoon but at least wifey does not know this.
Boarding the MV Magellan (Pictured) at Tilbury Dock I was eager to get the handheld going. As per the conditions of our Licence you have to gain the Ships masters permission to operate on the vessel. Running off, I go the the reception and ask them to contact the Captain for my authority to transmit.
Two and a bit hours later I return to the Reception and good news, permission granted. Intending to use the club call sign MX0XYD, I’m now fit & ready to use /MM (Marine Mobile)
Refueling problems meant the ship delayed its departure until 4PM some 3hrs later than scheduled (no need for my spare battery) Only wanting to use the /MM suffix for the day meant having to wait until we was under way heading east along the Thames Estuary.
So on the top deck and at the stern of the Magellan I managed to get just five contacts using VHF and the repeaters GB3DA & GB3ER. The cold wind, shed loads of QRM that Friday, Sunset and a double Rum calling meant that it was time to stop being a Ham and revert to being Hubby again for the remainder of the voyage.
Was it worth the hassle from the XYL? Was it worth the trouble getting the ship masters permission for 1hr 10Mins of radio operations?
Dam right it was…
PS, A big hello to the G6 station who come and said hello whilst I was operating, Sorry I did`nt catch the remainder of the call sign or even your name, but if he reads this he will know who he is.
