[OZAPRS] VK2US-1 To close.......

[Peter Illmayer]

Pete (vk2us) where is that photo of us putting up the antenna ?  Remember
the FM92, we drove just over the ANZAC bridge and the thing was as deaf as
a post.  We put in the 828 and it could hear us out near Lithgow....!!

Its funny to thing that 4 bolts into a roof, a temporary concrete pad and
the thing sitting ontop of a power box in a passage way could get in the
way :-)..Its all about policy.....

I remember getting Colin in there with his spectrum amp to see how bad the
environment was, rather ugly...
