Great detective work, Doug!
I don't have all the fancy gear here, but I can confirm that, from a simple J-pole at Eatons Hill, I can see a moderately strong pager burst on 148.8125 coinciding every time with a triggering of VK4RBN. Seems to also be affecting VK4RAX maybe 4 times out of 5; I can't yet correlate it with the triggering of VK4RCC, though.
It only seems to hit VK4RBN on initial TX; listening to a couple of particularly long bursts on 148.8125, the repeater is dropping within a couple of seconds and not reopening until the next burst commences.
My FT-8800R isn't seeing anything on VK4RBN input from here, for the record (but I am blocked by hillside in the direction of the Mater.)
Now, off to go hunting for one of them thar SDR dongles :^)
