@james I'm on the east side of Wolverhampton (in a pretty dead spot for VHF comms) and tempted to flash a few devices with up to date firmware and give it another go. From Sedgley Beacon with a yagi I got 63 miles a couple of springs back and used to see plenty of nodes when driving with Meshtastic turned on on a tiny homemade j-pole.
Where are you based and what software/frequency are you on that it's completely dead?
