drove up north of Terrey Hills to a high lookout overlooking Cottage Point & Akuna Bay , ( 33deg 38.06min S, 151deg 12.56min E, QF56OI alt.177m) using the Double-Quad antenna I could key up the Newcastle repeater VK2RTZ 1273.100 / 1293.100 it came back with a signal strength of 10/9.
In comparison to Somersby repeater VK2RAG 1273.400 / 1293.400 which came back with 60/0 signal. Both repeaters have voice ident. Gave some calls, but nobody around.
Tried to key Dural repeater VK2RWI 1273.500 / 1293.500, no luck, it is deaf. But switched the Double-Quad antenna to horizontal polarisation, I could hear the VK2RWI beacon on 1296.420 ok
Chatswood repeater VK2RWC 1273.200 / 1293.200 was a no show, but this was to be expected, as I was in its shadow.
