<DIV><FONT size=2 face=Arial>Hi Carlos,</FONT></DIV>
<DIV><FONT size=2 face=Arial>thank you for the kind offer.</FONT></DIV>
<DIV><FONT size=2 face=Arial>ROBUST PACKET MODE also called RPR is a
proprietary mode from german company SCS -the inventors of PACTOR- so I guess
you would need a DSP-TNC hardware modem or an SCS PACTOR Modem , that does
support RPR.</FONT></DIV>
<DIV><FONT size=2 face=Arial>Then you could connect it via USB or serial to the
RASPI , ODROID or PC running an APRS Gate Software.</FONT></DIV>
<DIV><FONT size=2 face=Arial>The mode has 8 carriers with 50 baud each with
adaptive OFDM modulation</FONT></DIV>
<DIV><FONT size=2 face=Arial>that will tolerate a frequency offset of 800Hz,
which is very helpful, when operating mobile with changing
temperature..</FONT></DIV>
<DIV><FONT size=2 face=Arial>and DSP-TNC can demodulate several signals at same
time...</FONT></DIV>
<DIV><FONT size=2 face=Arial>You can use it for hf-APRS and for PAcket BBS on
HF.</FONT></DIV>
<DIV><FONT size=2 face=Arial>adaptive speed is R300 and R600 Baud.</FONT></DIV>
<DIV><FONT size=2 face=Arial>center frequency is 1500Hz and less than 500Hz
BW.</FONT></DIV>
<DIV><FONT size=2 face=Arial>I have heard that a normal sound card would not
have sufficient timing stability to cope with this mode, but never
tested...</FONT></DIV>

Vol 110, Issue 5<BR>><BR>> Hi Mike<BR>><BR>> For standard 300 Baud
with the following audio pair 1600/1800 you should be on 10.147.60Mhz (not
10.147.30Mhz as mentioned).<BR>><BR>> I was running somewhere between

Mike<BR>><BR>> The following iGates were all active on 30m in June, when
I travelled from Darwin to Kalkarindji and back.<BR>><BR>>
VK8KMD-10<BR>> VK6LD-4<BR>> VK2OL-5<BR>> VK4MQ-4<BR>>
VK4AB-4<BR>> VK5THB-4<BR>><BR>> There are no doubt others, but these
ones gated me, on the above trip. (I have once been gated via a European
iGate.) For the area that you are going to, I suspect that VK8KMD-10
will be the main provider, we will watch with interest!<BR>><BR>>
