[CRAPRS] aprs igate/digi experiment

[Jerry Pasker]

ok, here's the deal:

I got a linksys wrt54g 'router', that's been turned in to an igate. 
(kb0qcl-1)  i suspected it was really poor at receiving, so i set up 
a little experiment.  back at the home shack's kantronics kpc3 digi 
(kb0qcl) i put a stereo splitter cable on the output of the radio to 
let the kantronic kpc3 digi run normally, and put the other output in 
to the router-linux-igate.    i didn't bother changing kb0qcl-1's 
lat/long.  so it shows as being in the country, but it's really in my 
basement.

my logic is that if the kb0qcl-1 igate can hear the packet, it'll get 
to the core aprs servers first, and any kb0qcl digi packets will be 
ignored as dupes.  if it misses the packet, kb0qcl will transmit it 
and it should make the internet eventually.

kb0qcl-1 is not transmitting to anything, it's receive only.

since kb0qcl-1 and kb0qcl share the same radio, kb0qcl-1 will never 
hear any packets directly from kb0qcl. but, i think it should be able 
to get them from k0ham-10, or ka9bab-13.  but it seems to even miss 
most of these packets!

so...to see how poorly an opentracker1 in kiss mode receives packets, 
simply look at how many packets kb0qcl gets that kb0qcl-1 misses.

eventually, i think i'll hack an opentracker2 in to the igate, to see 
if it receives any better.  once i can solder again.  ;-)

is my logic sound for this 'experiment?'
