It would be good if users could post reflectors they have found of interest, apart from 4400.
Recently I have used 4426 on BrandMeister. This is connected to the AllStar HubNetwork.
This bridges DMR and analogue in places, and is linked to several simplex gateways and repeaters country wide and possibly further afield.
I was informed today that GB7PK has been closed down.
It is now possible to connect to all of the modules on all of teh XLX reflectors listed here.
This works as follows:
To change XLX reflector – prefix with 68 – e.g. to connect to XLX235, you send a private call to 68235.
To change XLX module, it’s the same as before, e.g. 64001 connects to module A, 64002 to module B etc.
You should hear voice prompts when you do this.
Many of these reflectors have a D-Star <->DMR transcoder, so you can talk to D-Star users.
I have finally got around to making new, double screened patch cables for the duplexer. This means, if there was any desense this should have improved so weak-signal performance could be better.
I forgot this update this before. It seems Phoenix reconnected 4400 on DMR+ to their TG235 again!
I’ve been thinking about the antenna for FR. I have decided to seek to fund a new antenna with greatly increased gain. It will be big, apparently a full 17ft tall, but this will also provide an advantage. It has about 12dbd gain. Also, it has more gain at the horizon than the current antenna and a narrow vertical beam width which, considering that FR is not sited at a high point, will likely provide better coverage.
The Phoenix people have decided to disconnect their TG235 from reflector 4400 on DMR+ so this can no longer be accessed from FR. The rest of the DMR+ <-> Phoenix linked TGs, including the regional ones, remain unaffected.
SMS, Parrot etc are now all working as expected.
XLX reflectors have moved to TG6, with a prefix of 6 before the commands – e.g. 64005 to connect reflector E on XLX 950.
I have chosen to use a different TG and prefix for each network, so that contacts for private calls in your radio don’t clash as most radios won’t let you have two different named contacts with the same ID. So:
TG 6 slot1 – XLX sytem – prefix 6 to commands
TG 7 slot1 – as yet unused. Reserved for another XLX connection
TG9 slot1 – linked to PK and BH as before
TG23510 slot1 – SouthEast TG
TG8 slot 2 – DMR+ reflectors. Prefix 8 to commands. Defaults to disconnected.
TG9 slot 2 – BrandMeister – no prefix required.
Private calls, SMS and UA talkgroups on either slot are directed to/from the BrandMeister network.
I have a new and exciting feature to announce. Jonathan, G4KLX has written a new piece of software that allows the connection of more than one DMR network at once, so as of today, FR is connected to Brandmeister, DMR+ (and by extension Phoenix) and XLX. Note, this is still experimental so some of these options might change. Feedback appreciated.
- TG23510 – South East
- TG 9 – Regional link – FR, PK, BH
- TG 8 – XLX reflectors
- TG 9 – Brandmeister reflectors – default 4400
- TG 8 – DMR+ reflectors – linked to Phoenix
XLX implements 26 lettered reflectors, A-Z. These can be connected by making a private call to IDs 4001-4026 on slot 1. I am told most DMR activity is on 4005. These reflectors are cross-mode, so you can speak to others on D-Star, YSF etc. To disconnect, use 4000. To get status, use 5000. This is basically the same as BM/DMR+ reflectors.
A list of XLX reflectors is here:
Using BrandMeister reflectors:
This works exactly as before, so you can continue to use the system as you already do.
Using DMR+ reflectors
All DMR+ reflector activity will be transmitted on TG8. To connect, you prefix all commands with an 8. (Similar to using a phone in an office; dial 8 DMR+ “line”!)
So, for example, a private all to 84400 connects you to DMR+ reflector 4400 / Phoenix TG 235 UK Wide.
A list of DMR+ reflectors is here:
It is my pleasure to announce that FR has been on-air since this morning.
One of the GM350 units had developed an intermittent fault, believed to be in or around the AF IC, which provides AF processing for both TX and RX audio paths. Fault-finding proved frustrating!
Andy, G3UEQ assisted with the kind offer of a GM900 unit, but I couldn’t get it to programme. Paul G7KBR then kindly posted me a GM350 4ch unit, which I was able to programme and is now acting as the RX for GB7FR.
As always, setting up the TX deviation was a bit of a fiddle as I don’t seem to have any luck with the theoretically correct deviation, as tuned using an RTL SDR. The signal was received fine on my MD380 and PD365 but not on my MD650, which is extremely fussy when it comes to TX deviation. However, a slight tweak allowed the MD650 to receive the repeater and now all seems to be working well.
Reports are welcome, especially from owners of radios from manufacturers other than Hytera and Tytera.
