Can you explain something to me ?<br>
<br>
I assume that in a heavily populated area there can be one or two iGates<br>
for Internet connectivity and as many digipeaters as you can muster - to<br>
help get better and better coverage to the whole area and the blackspots.<br>
<br>
If all of this is done on 145.175 MHz then things can get congested pretty<br>
quickly with heavy traffic - and packets will be lost.<br>
<br>
Are there any working examples where people have put in dual frequency<br>
digipeaters - where the primary frequency is 145.175 MHz and an extra 70cm<br>
frequency is used as the dedicated link to the nearest iGate ?<br>
<br>
Would such a system help with congestion and reduce the loss of packets ?<br>
<br>
My APRS kit came from the Oxley Region Amateur Radio Club and is a little<br>
beauty. It uses a UV-5R handheld radio as the RF device which works<br>
pretty well with a decent antenna on the roof of the car - but at only 2<br>
watts output it just cannot compete with other stations running 30-50<br>
watts so in busy times my signal doesn't get through and gets squashed.<br>
<br>
Assuming the nearest digipeater hears my signal is there any guarantee<br>
that the data gets through from that digipeater to the iGate ? So do<br>
digipeaters and iGates have a special relationship to get the data through<br>
at any cost ?<br>
<br>
And another question relating to Newcastle. Our main digipeater is up on<br>
the Sugarloaf Range and the nearest iGate is on a large building in Hunter<br>
Street West - in the Newcastle CBD. If I'm driving around Newcastle City<br>
do my APRS packets have to go via the Sugarloaf digipeater and then to the<br>
igate - or if I am close to the iGate will it accept my packets ?<br>
<br>
<br>
Very interesting stuff, thanks, Jamie VK2YCJ<br>
