You noticed that too, eh? hi Maybe Bob (and some of the other 240 stations) 
need to shorten their path a bit. In Bob's defence, Bob has already 
mentioned that some of the 240 stations only show up at his QTH a few times 
a day. I'm probably in a similar situation. I'm looking at UI-View with a 
TCPIP-only connection right now, but for the last few weeks I was running it 
with either a KPC-3+ or a TNC-X as a digipeater (as well as the IGate that 
has been running for several years), and I was seeing virtually the same 
station list. Most are coming from the two "high density" areas around 
here... Vancouver BC & Seattle WA plus all of the surrounding area. However, 
there are lots of stations from the interior of BC (and a few in WA state) 
that were making it here on RF over very long distances. I think the APRS 
users in the very sparsely populated but mountainous areas of BC feel they 
need a longer path to make it to one of the few IGates up that way. A 
consequence of this is that quite a few of the stations in northern BC and 
the Okanagan also make it on RF down to the Vancouver area... a distance of 
about 600 km for some of those stations. However, quite a few of the digis 
up that way also show up down "here" on RF too. They aren't in my ALOHA 
circle, but I see them. Did I mention that I usually use a one hop path for 
any digi / IGates (fixed station) that I run here? Perhaps I'm in a fairly 
unique location here. I have a fairly large footprint even though I'm not at 
a great altitude, but I also have several large footprint digis within 
earshot as well.
