[OZAPRS] Alpine Rally - APRS & RF conditions

Tue Nov 27 19:46:51 EST 2007

Dick,

You bet I am.

Now that APRS in Australia is on the same frequency we are all on the one
Big National APRS Network and should respect and appreciate it.

What you do locally in your town will have an effect on a station in Perth
or Brisbane if the conditions are right. No one is isolated on their own
network anymore, unless you change frequency to something other than the
National APRS Frequency.

As I stated in the email I did not for see the issue until it occurred. I
though that in the spirit of Amateur Radio and assisting our neighbours
there may have been some positive results to my request. May be I was
wrong.

In the future there will need to be some pre-event cooperative
coordination
for the National Network we all now have. This will assist use in helping
each other.

Cheers
Richard
