[OZAPRS] HF to VHF Confused

[David and Justine Olsen]

Andrew

Thanks for clarifying that.

I wonder what range you did your testing over? I travel regularly in  
Central Australia SA Deserts and the Kimberley and can talk to home  
(Townsville) most days on 40m and 8MHz VKS.
For me personally the ability to report my position at beginning and  
end of day is more important than during midday, and I think that  
would be the case for most people traveling away from VHF regions.  
Just how many of us are standard calls I have no idea. I am doing my  
advanced call study now, but 5 months of travel will put a halt to  
that :-)

Anyway it will be fun to see what happens if I run the iGate 24/7  
while I am away, and have my vehicle reporting position for 5 months.  
I think not too many people would have the opportunity to run a test  
like that one.

I will be in Simpson Desert from May to mid June then Cape York (20m  
will be useless Cape York to Townsville except from the very tip)  
Then in the Gulf and Kimberley Regions until end Sept
