Dave and Walter have commented on the crowding around 136.922.
We did have an agreed plan which avoided Loran lines and separated stations.
It listed frequencies from 135.7080 to 135.7589.
136.9220 kHz was my frequency, but I can't use it now !
This plan was posted on Mike Dennisons web site, I would like to see us
return to it.
