It looks as though the 5.7GHz wireless LAN link that provides an Internet connection to the Weedley radio site from my QTH has been fixed at last.
The link started dropping out but always seemed to recover from a reboot at the Weedley end. The dropouts became increasingly more frequent and the cause proved difficult to locate due to their intermittent nature and because the fault cleared as soon as you started to work on it. We also noticed that the head unit would not work on its original frequency and would only link some 200MHz lower.
A process of elimination has isolated cause to be the switched mode wall-wart power supply that feeds 24vdc to the power-over-Ethernet injector. This is the power source for the 5GHz wireless head unit. Having replaced that it was found that the link could be put back on its original channel, well away from all of the mush radiated from the numerous links used by the three wireless Internet companies operating in Hull.
It's now stayed up for a week so hopefully it will stay up. All that grief for a £4.70 power unit!
