Hi Chris,
Kingstone
is showing on ognrange.onglide.com. The 'Pin/Balloon' on the map switches between the PW and OGN version of the station (presumably related to which last updated the OGN servers), so it's often easier to select the station you want to see by typing its name in the header box then select 'Goto', though annoyingly you still then need to physically move the map to the right part of the country.
How long has Kingstone been up and running? I guess about a month as extending the 'When' tab beyond 30 days doesn't show any significant additional coverage.
Looking at the other stations in the area, it looks like you are on the edge of several high gliding activity areas but possibly fairly low down. Is this correct? If so, you just need to wait 'til your coverage map builds up. Mine (Balerno / PWBalerno) took quite a while as I am quite far away from the main gliding activity, with Edinburgh TMA in between and with my antennas still inside my loft. If, however, you
are in a high gliding area which has been active recently, you might need to reassess your installation if the coverage doesn't build up.
For comparison, look at OldGore near Ross on Wye, which though in a similar situation to yours near gliding areas shows
no activity whatsoever over the last 60 days, though extending out to 'Since 31/03/2015' brings 'limited range' contacts into view. The Pin is green and the station still active, so I did a little digging...
Another site you might find useful for monitoring your station performance is 'Grafana', though be aware it only updates every 24 hours, sometime after 1am and the data it provides is 'limited' to technical data re the station itself.
http://grafana.glidernet.org/dashboard/db/receivers?orgId=1&from=now-60d&to=now&var-receiver=KingstoneYour traces on Grafana look pretty 'normal', whereas changing 'Receiver' at top left to 'OldGore' (start to type in the name and it will come to the top of the dropdown) and extending the time range (top right) out to 1 year shows a sudden drop in RF Input noise at OldGore back in February, which seems consistent with no data since then and most probably indicates a problem. Just using this as an example, though. Don't get too hung up on minor variations on the Grafana site.
Hope this helps.
Regards
Peter
