2019 Perseids - back scatter screenshot

Post by daveB » 14 Aug 2019 12:21

Back-scatter meteor reception. BBC R2 (89.7) and BBC R3 (91.7) on the same burst as Sweden and Denmark. The frequency combination shows it can only be Talconeston (Norfolk) or Redruth (Cornwall). Talconeston is uses 130kW hor omni-directional, Redruth uses 2.5 kW hor to the east, so it is 95% certain Talconeston at 133 km line-of-sight. You will also note that is is being received weakly by direct line, and also you can see 94.1 also hs an M-S burst - a choppy mix of BBC R4 and a german speaking station.

I'll add a screen shot - an expanded 10 second burst to show the typical choppy signals that won't give RDS

And the best burst, so far, of 2019 is shown under it

Edit - sorry having trouble with attaching the pictures - I'll put them as links instead - DONE

It is very likely that the german station on 94,1 is WDR2 Munster/Baumberge.

It could also be NDR 2 from Göttingen-Nikolausberg. At 5 kW it is similar in power to some of the other reception I've had via MS on 13/08/19. It is 632 km away.
