OK my #Meshcore friends, what am I doing wrong?
Board is on the 3rd floor (over 6m above ground height.
Powered on, connected via Bluetooth, by a window.
Set to UK long range.
Been up for about 30 minutes and hasn't discovered any neighbours.
I know there are a couple of repeaters near-ish.
Just a case of wait and hope? Stick it in the loft? Increase power?
Any help and speculation welcomed 😄

Aha! I had to unbend the antenna 😁
Now receiving #Meshcore messages. Don't know if any of mine are being seen though.

Well the #Meshcore is *sort of* working.
With it's new placement I can just about hear one repeater.
I'm receiving some messages, but I guess my antenna is to puny to send any.
My noise floor looks good (I think) and I've discovered a few nodes.
I think I need more power and/or a bigger antenna.
If you're on the mesh, feel free to send me a message and I'll let you know if it arrives (details above).

Discovered more #meshcore nodes overnight, but still only infrequently receiving messages. Will try moving the tiny antenna to the loft - although that will reduce my Bluetooth connection to it.

Stuck the #meshcore in my loft. Hasn't meaningfully changed the signal strength.
Might try some different equipment or switching to #meshtastic.

On the advice of several people, I stuck the antenna at the highest part of my loft, pointing down so it wasn't in contact with the roof.
Signal strength improved - but still poor.
Still can't actually send messages to the nearest #Meshcore repeater.

@Edent do you have any metal flashing under your shingles? That could interfere. Do you have any obstructions on the outside of the roof very close to your antenna?
Hams call attic antennas “compromised” but plenty of hams also have success with attic antennas. Have you confirmed all your settings are correct by trying to ping a very close repeater? Like less than 25 meters away?
@K3LOE solar panels on the roof.
Nearest repeater is 4km away.
I can hear it - but nothing hears me.
@Edent Sorry, last thought: it’s not unusual for receive performance to be better than transmit performance. It takes power to move a signal through the ether and you don’t have much with unlicensed meshcore. It’s a lot easier technically to hear what others are sending out.
