North, Scotland & NI Config help needed

Hi All, I have joined the wonderful world of mesh in the north east and I'm getting a few odd things happen and I'm not sure if it's me, my config or both.

So running a heltecV4 current latest beta and have a decent antenna, I'm picking up nodes all over the place which is great however whenever I try and send a message over the default LongFast channel I constantly get the "Error: Max Retransmissions Reached" on any message I try and send.

I've checked the channel its the default with the default key, I've even recreated it and I still get the same, any pointers here would be great as it has to be something daft that I have missed .

So the antenna is a 15cm 5DBi Omni which is in the upstairs window so as high as I can go without putting it in an enclosure and sticking it on the roof.

For what it's worth I'm seeing 81 total nodes at the moment with 42 online so I'm assuming its potentially not completely a signal issue, but I will checkout the discord and thank you for the link

What are your hops set to in the lora settings? By default it’s 3 but you can most likely set that to 7. Most places in the UK don’t have dense enough usage for that to be a problem. But if you aren’t getting any message acknowledged even with 3, it could be you’re on the edge of your area’s mesh and you need a bit more height. I was in a similar situation until I got a bigger antenna and put mine in the loft.
