It wasn’t until I put a scope on the ADC pin on the Due that I noticed there was a bit of low-level desense showing up on the the repeater. The TX and RX radios were sitting one on top of the other. I have separated them by a few cm and the desense appears to have gone. I wonder if this will make the repeater perform a bit better with weak signals….
In the event of weather causing a localised or more widespread communications loss locally (mobile, internet etc), I will keep a listening watch on TG23510 (South East) on S1 of the repeater and I would ask other users to consider doing the same. You never know when someone might need it.
If you’re venturing out in this weather, grab your radio on the way out; it can’t hurt!
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.
