[Lowfer] Odd 137 kHz Propagation

[Howell, Laurence (Shanghai/Singapore)]

I visited the old XDW site this evening and the trees don't seem to have suffered the 40 amp antenna
 current running nearby for a year though the squirrels all ran away when the saw me....I miss the gear too, all locked/stored forlorn looking in Dallas so it seems.

Yes, this has been documented a number of times before. Think I saw it most 
often on XDW. Still miss the big signal out of OK ;~(
