Comment(by Quozl):

 I've tested two B4  XOs to 1.6km repeatedly, but they were the same two,
 and there were no other XOs on.  When I tried a mesh test three or four
 months ago with six XOs (3xB1 3xB2), if they all pinged at once the range
 was about 30m at 10% packet loss.  The range increased as the mesh was
 more silent.

 I agree, checking the units for problems would be good.

 Some other ideas ... interference from military radar, extreme humidity,
 thick grass or vegetation on the ground, solar noise, obstruction in
 fresnel zone of path.
