I didn't work on links in Post Office Telecoms, but we used the West Coast microwave network for the Manchester-Glasgow links on the Expereimental Packet Switching Service (EPSS) in 1974-1978.
In bad weather, we got drop-outs on the 48Kb/s (yes, Kb/s not Mb/s or higher!) circuits we had on that link. I was told that we were getting over 40dB extra loss on the RF path, compared to normal conditions!
