Mike i was trying to talk with you but i dont think all my messages were getting through, sorry
Ya I was getting all Ur messages
But unsure you was seeing all mine
Hi all, happy new year.
If your not sure if the ‘mesh’ is hearing you, or not receiving any replies, then have a look at
https://analyzer.letsmesh.net/packets
It looks a bit complicated at first but click on the drop downs and all will start to become clear. Set the region to CAX - Carlisle, Cumbria, GB.
Then send a flood / public message and see if after a min or two it appears on the screen as if by magic, you may even see any replies that your not getting
CumbriaCQDent is deployed

Reinventing the wheel yet again
Just found that Meshcore already had the answer … flash a v3 on 433 (for my in town mesh) and a v3 on 886 (for the world at large) using the ‘Bridge’ nightly builds, I think its working
The 433 companion should cause the 433 repeater to talk to the 433 esp now and then onto the 868 esp now and onto the main 868 yagi …. kinda
If it works then I can reduce everything to maybe just 2 repeaters and 1 companion
Hi dave, doesnt this cause issues for non licenced hams TXing over 433 ?
Showing results forUnited Kingdom
In the UK, the 433 MHz frequency band is legally available for use by short-range devices (SRDs) under specific regulations set by Ofcom. This band, spanning from 433.05 MHz to 434.79 MHz, is designated for non-specific short-range devices, including remote controls, security systems, and telemetry applications. Devices operating in this band must comply with power limits, such as a maximum of 10 mW effective radiated power (ERP) and a duty cycle limit of 10% for higher power levels.
However, the 433 MHz band is shared with amateur radio operators, who have primary rights in certain segments, particularly for simplex and repeater operations. This means that SRD users must accept interference from licensed amateur radio transmissions, which can affect performance. Despite this, the band is still considered legal for SRD use as long as technical requirements are met.
For example, the Black Falcon 3-Channel System, a product designed for falconry, operates on 433 MHz and is explicitly stated to use a UK legal frequency. This confirms that 433 MHz is permitted for specific applications in the UK, provided they adhere to regulatory limits.
In contrast, the 868 MHz band is also available for SRD use in the UK, but it is more commonly used and less congested than 433 MHz in practice, making it a preferred choice for many applications. Nonetheless, 433 MHz remains a legally recognized and usable frequency in the UK for compliant devices..
In short its legal but kinda useless for unlicensed usage, but in Dumfries using more db it works better for filling in the holes

Gone quite over on the home front in Carlisle not heard a peep in days
Well done Dave. What frequency does meshcore say to use ?>
Yeah havent seen you. wonder which repeaters gone down..
It doesn’t say …. so I’ve been just messing about until something seems to work, of course the 886 bridge side of things is our normal settings, the esp now seems to take care of its self via the little coil antenna on the board (as the 443 and 886 bridges are next to each other I’m not bothered about installing 2.4g antennas)
Ive been thinking about a potential meshcore problem as the network grows ever larger. That is messages colliding and therefore not getting through. I imagine this will be a much larger issue through critical repeaters in busy areas. I don’t know if meshcore has provisions for queueing messages that arrive at the same or similar times and is smart enough to stop this happening.
I wonder if we’ll see dual channel radios or dual radio repeaters reccomended as the project gets bigger. not a send and recieve frequency, but a main and redundancy to stop messages overwriting one another. a bit like signaling on a trainline.
either this, or its going to need to have some sort of per-hop handshake on messages sending and arriving whihc would congest the network.
The things that keep you awake at night #32,456
And now the wind / rain / snow / ice has gone, I’ve started building the tower … may finish on Saturday (Thursday is shopping day, Friday may be a bit of a Boozey day)

How Exciting @MM7FGU I want to see the end results and where you bought all that from. Might be my new antenna Aray soon. all in one place.
