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

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)

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.

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.
