<DIV><FONT face="Trebuchet MS" size=2>There were technical and band planning
considerations that put the USA on your "custom (non-standard)" frequency for
APRS. Historically, APRS gained a foothold on 145.790 and was moved
from there. The 144.800 APRS channel that you find yourself on would not
work in the USA since 144.790 and 144.810 are inputs to terrestrial FM voice
repeaters. See the "<STRONG>APRS/Manned Space Frequency
Alliance</STRONG>" article by "<EM>Frank H. Bauer, KA3HDO</EM>" at </FONT><A

<DIV>What custom ("non standard") frequency are you on about? 144.800 MHz is
the correct frequency for APRS world-wide. It's only the USA that uses a
custom (non-standard) one! </DIV>

<DIV>Sometimes it gets really frustrating that Americans can be
so parochial -- always thinking that their
view/regulations/frequency/digipeating is the only one that's right. Someone
has gone to the effort to organise a self-contained device, on the right
frequency for people outside the USA, and you seem to be detracting from it
and their efforts. Good on them!</DIV>
