[OZAPRS] Surpise for 40m !!!

I'm halfway between Brisbane and Sydney, near Kempsey, and I've logged 
171 packets from you on 30m to 12.15 today.

If you can get the right path on 30m you'll see some amazing connection 
times. 900 to about 2100km seems optimum. When I ran the bbs on 30m I 
consistently had 22 hours per day with vk5uj (about 1100km). I did as 
well with a vk3. The only place Oz could do with a 30m Igate is around 
Alice Springs, and maybe the NW of vk6. The existing network seems to 
provide good coverage. My heard list for the last 24 hours shows
W7CCY - heard almost daily

David, VK4MDX, has had success with 40m but the number of Igates is 
limited compared with 30m. In my years of running the bbs on both 30m 
and 40m I never found 40m open as long as 30m, and the extra noise 
(static crashes, etc) on 40m was a nuisance, even in my rural location 
where standing noise is typically S0. It's horses for courses and David 
was driven to 40m for licencing reasons. I believe he's quite chuffed 
with his success there.
