A new UHF repeater has come on-air this week, It is a P25 / DMR digital repeater.
It’s transmitter output is on : 439.750 and it’s RX: 430.750.
The P25 repeater uses the default NAC of 293 and Talkgroup 2 and, and if you are out of the area or are unable to get in via normal RF means, It is also linked to the ‘Morecambe Bay Talkgroup 2 reflector’ which also allows P25 users to access the repeater via the internet.
The DMR side of GB7MP is colour code 3, and is connected to Brandmeister, and here’s the thing, there are no Brandmeister talkgroups assigned, so you will need to check the standard Brandmeister Talkgroups that you intend to use before you program.
The reason GB7MP does not carry Brandmeister talkgroups by default is that the repeater is primarily a P25 repeater and lots of busy DMR traffic would render the P25 part of the system unavailable to the primary P25 users, but you have the option on using GB7MP or GB7MB, remember GB7MB is DMR only and thus 100% availabile for DMR use anytime, and MB is on the Phoenix network, not Brandmeister. MP and MB are *not* directly TG9 linked like UZ was before UZ went off-air.
Just a note about the echoserver, program it as a private call, not a group call, like it is on Phoenix.
I quote Dave, G6CRV the Repeater keeper of GB7MP
“All the reflectors have an associated Talk Group, if you don’t want to enter all the talk groups into your radio, then you can connect to the associated Reflector by using a private call. IE private call to 4412 connects you to TG23520 (North West) and connections to reflectors time out after 5 minutes if not being used ”

Well, You can certainly do some neat tricks with SDR’s nowadays, clever things like making your Raspberry PI transmit AM/FM/SSB and the (slightly pricey) but very interesting HackRF board. I see Fenton Dynamics have been busy lately, they’ve rebranded now from BriCom, and i completely missed them first time around, Anyway, this device, which is sort of a set of modular clip-on-goodies for your smartphone can magically turns it into a VHF / UHF P25 / DMR / FM / HT is available, and, not that you can tell, but the photo above is of the 2w VHF iPhone 6 version apparently, well so it says in the blurb, all wrapped up in a Nextpaq case.
For more info check out their August 2015 Youtube posting HERE and head over to Fenton Dynamics too, if you have a supported Android or IOS device it may appeal to you .. it does far more than what you’d think, with a dual band module, DMR, and P25 modes, analogue signalling like MDC1200 etc, trunking, GPS, ROIP, SOS, alarms etc, and there’s an SDK kit available for third party developers too, and hopefully the apps that will appear as well. It all seems very modular and well thought out, the clipon goodies even has their own mic and speaker and battery, and it’s all neatly wrapped up in a $99 Nextpaq case – with the actual Dxbm modules beginning at $65 it’s beginning to look mildly Interesting. Watch this video or this earlier video which hopefully gives a better idea of it…
