First of all apologies to everyone for the gaps & delays. I have no broadband here, our phone supplier is unable to get a signal to us this far from the exchange. Although we can't get a mobile signal, I can get a whisp of one from a yagi antenna on the roof. It is often quite good, but tonight there is a lot of rain & the signal intermittent. Even the speed test site takes 3 minutes to load its start page then gives up on the test!
Yes well done! It is built into a sand bag to disguise it as an observation port in a sandbag wall.
