[OZAPRS] QRG drift HF APRS

Wed Jun 29 22:49:37 EST 2011

Hi Mike,

The tuning information is interesting...

This is why we set up Net Stations several years ago. All VK HF APRS
stations should tune to the designated NET station (see
http://aprs.net.au/hf/hf-net-stations)  By all HF APRS stations tuning to
the NET station and not worrying about your radio's frequency display
everyone will be on the same wave length.

In most cases there should be a Secondary Net station for each frequency in
a different geographical location to the Primary Net station. This will
allow for station to tune in to the Secondary Net station if they are unable
to hear the Primary Net. The Primary and Secondary Net Stations would be
frequency synchronised.

Some of the Primary Net stations and Secondary Net stations have gone off
the air over the years and have not been replaced. We may need a few
volunteers to run their station as a 24/7/365 Secondary Net stations if they
can hear the Primaries well enough to tune in accurately.

It would be nice if VK6UK-4 wanted to setup as a Secondary Net station for
10MHz and tuned accurately to VK3MY-4.

Cheers

Richard

see how all stations on 10Mhz are drifting offset in QRG:

http://aprs.fi/?c=raw <http://aprs.fi/?c=raw&call=vk6uz-4> &call=vk6uz-4

It is not the absolute but the relative value to each other that makes the
problem in decoding hf-aprs sigs.

(values after callsigns is given in Hz)

G'day Russ,

Thanks for the reply, I've been meaning to set up a buy / sell page on the

Hi Michael,

Had a look at your club site.....pretty good.

If you or the club has a KP3 spare I would like to buy it and put it in
service as a digi in our area.

The only work out my KPC-3 gets nowa days is beaconing my weather station
from the ui-view32 software, cost me nearly $300 back in the day of packet
16 years ago, and it got a lot of work, but now, just seats in the corner of
the shack tx every 30 mins, I have always wanted to setup a Igate on hf (
40mtrs ), oh well, one day maybe if the wife is not looking at the bank
account I mite look at the KAM. 

Yours sincerely

Hi Shaun,

I've been running a Kantronics KP3 ($80 on VKHAM) with a IC2820 at my shack
for about three month now and it works a treat, VK2VK-5. (2M)

Software is Ui-View and running KISS on the KP3

I have just landed a Kantronics All mode "KAM" (runs HF and VHF) from UK for
$120 AU.

Hoping to be on HF within the week if work allows. I also have a FT-857D
that I hope to run my HF Igate on.

If I can be of any assistance give me a yell.

For your info. 

Regards

Russ  

VK2VK-5 Central Coast Igate

OK, I set the TNC back to 2m 1200 settings and all working fine, so it would

appear the 200 vs 800hz was the issue. Silly that Kantronics didn't address

the issue rather than just telling you it won't work.

I set my symbol to a bike as I had never really worked out how to do that
part

or the set up although for today I think I should change it to a boat with

this rain!

And for the info of the APRS.net.au people this link is broken in the

configurations page:  http://web.ew.usna.edu/~bruninga/aprs/symbolsX.txt

Once again, thanks for all your help.  Even though it didn't work I now have
a

better understanding of this part of our hobby.
