Hello to all
We would like to experiment APRS PAX (PAX not PAX2) transmission through a PAX
repeater.
Fred (OH/DK4ZC) proposes to be a PAX repeater this saturday 18/11/2006 from
15h00 to 17h00 UTC. His locator is KP30JK in Finland.
From 15h00 to 16h00 UTC Fred will beam towards Europe and from

Hello Simon,
I measured the minimum S/N (in general for about 2 % of errors) for all the
Multipsk modes (look at the chapter RX/TX modes selection and their
descriptions in my help).
I did not measure in fact the minimum S/B
Hello Rick,
As far as I know, there are very few specifications about Q15X25, only
generalities. However, for HF, the minimum S/N is certainly too high (surely
around -1 to +1 dB).

Hello Alves,
The QRPP experiments are very interesting. It is perhaps just a bit difficult
to hear you signal from over the pond due to the bad conditions (here in Paris
I did not hear your signal but I have nor a good antenna nor a good
location...).
A beacon is particurarly interesting for
Hello Jose,
I think the Multipsk version 4.1.1 can't work under Linux with ou without flute
music as i used in this version a DLL to measure the CPU load. But as this DLL
does not work in all XP versions and never in XP pro (why?), I've put this
feature only as an option in the 4.1.2 version.
Hello Rick,
If often wonder if a mode that has a very wide ability to print even if
not tuned in well has to have some tradeoffs in robustness compared with
critical to tune modes. Anyone have specific information about that?
The ability of DominoEx to be tuned very easily is that the
Hello Leigh and Jose,
The parameters to look for from Patrick are the RS code groups and
maximum correction coefficient. It is likely that the same seed data p
is used in all cases, so there is no need for a registry of data codes.
(I.e., if you can decode it, you don't need to know what it
this? Would it be worth
chosing one which we could use ? We do not have any band/baud restrictions here
(Canada)for this type of transmission so could use whatever suits European
stations.

Hello Andy,
Just an information about Multipsk or Mixw...and Commander.
The global control may be summarized according to the following diagram:

Hello to all,
If you do Digisstv transmission you must use very small pictures,
for example the Mini_Map.BMP file (in the Multipsk package) which
dimensions are 80x70 pixels.
