[aprssig] followup on my firenet filters thread

(Attn: Pete Lovell, if you're on this list.  Is an ambiguous posit valid 
for an m/ or f/ range filter?)

Ok, that's the information I needed to see.  Remove the colon from your 
filter and I suspect your old one will work.  The old javAPRSSrvr 
wasn't/isn't very picky about the adjunct lead-in word, but the new one 
is much more persnickety.  And with the r/42/-72/200 term in there, and 
no m/ filter, the server never needed to know where you were located.

However, you'll see how javAPRSSrvr 4.0 converted your m/500 filter to 
an f/K1KWP/500.  It is therefore expecting to know where K1KWP is 
located.  Looking at aprs.fi's raw packets, I see that you are providing 
that information (see http://aprs.fi/?c=raw&call=K1KWP), but I cannot 
help you with why the filter isn't working.

Wait a minute!  I looked a bit closer at your posit packet and it is 
transmitting an ambiguous position! I suspect that the new javAPRSSrvr 
(and maybe the old one as well, but you weren't using an m/ filter 
before) may not consider an ambiguous position as being "close enough" 
for any range-based filter from that station's location.

2012-10-12 15:57:35 UTC: K1KWP>APX201,TCPIP*,qAC,N5JXS-F1:=4216.0 
N/07143.5 W-PHG3200Kevin in Shrewsbury-XASTIR/fedora 17

But if you remove the : on the old filter, you should be back to the way 
it used to work, without caring where K1KWP is thought to be located.
