How do I know a gateway is operational?

Hi Jeff

I was getting hits on my console from 12:23, from near to you, with SF12, and I changed to SF7 at 12:31. Then I parked in the car park where I believe you are located. No more hits, so I changed back to SF12 at 12:55. Still no hits, so I drove home, stopping at the Park and Ride for a few minutes. I got a screen grab of the first couple of hits - I realise if I had scrolled right, I should have been able to see the lat and long, but didn’t realise at the time. I saw more hits, but didn’t screen grab. It will be interesting to see yours.
