I seem to remember the link transmitters were pretty reliable. I think they used to auto shut down the remote TX if the receive path was lost. They did suffer when there was a lift on. I remember being on a site near Kendal and every link was chattering on and off due to long range interference. I think the links ran about ten watts into either a three or five ele yagi on horizontal polarisation. They were all replaced with Philips L700 microwave or those orange Plessey jobs when the main Tx went onto 154/155 MHz sometime in the eighties. The main Rx's were more of a problem to set up. Who remembers trying to align the tones on a Pye ASSORT voting system? Hours of frustration. Happy days.
Alan.
