Consol
mstjbrown, Used whilst yachting having first laminated the consol chart. In the channel often found Bushmills hard to receive, so not getting a good fix, never trusting a poor cut of two lines.
To continue the thread creep, you count the dots & the dashes as check sum to determine how many you lost in the equisignal. In some sectors dots were first in the others dashes, a bit like As & Ns on a range.
There were other sets of stations mainly Soviet with I think the last to be withdrawn fairly recently on the Pacific coast.
Heaven help us all rambling on about 50 years ago when I can't remember where I left the keys 10 minutes ago!
