[OZAPRS] RE. Making Contact

[Geoff]

Correct in both cases.

MY POSITION on both the D700 and D710 (MY POS on the D7 HT) indicates that
the radio has heard its own beacon. The only way this can happen is it has
heard the digipeated version via one or more digis.   Around Sydney you
could easily get 3 repeats, as VK2US-1, VK2RAG-1 and VK2RUW-1 have an
overlap in coverage over parts of Sydney.  If you are out west or up in the
Lower mountains you could get 4, as VK2RSW-1 Fill-in digi also comes into
play.

Sometimes you will hear the packet of another VoiceAlert user and not decode
it - remember it is a SIMPLEX operation, so the other station may be right
on the edge of your receive capability, or just in a 'bad spot' to you.  You
will probably find that your radio will display the callsign of that station
as it is heard via the digipeater. . .   So check the next couple of packets
following the audio you hear - you'll only hear the audio from the original
station, not the digipeaters - as they don't repeat the subtone :-)

Dave,

Thanks also for your reply.

Starting to make sense now.

Can I just ask another question:

When my 710 transmits a packet and after a second or two three I see on my 
display "My Position" (The actual words) accompanied by a different beep. 
Sometimes this happens once and sometimes 2-3 times after each other. Am I 
right in saying that that is because I am receiving kind of my packet back 
from a digipeater or a few digipeaters?


Also, sometimes I hear the digital audio on 145.175 meaning it must have had

the squelch tone 91.5 on to get though on my set but I do not see any 
details on my screen. Is this because the packet was not de-cypherable or 
valid?

Kind regards,
Gerard
