Based on the advice below, I have changed my TX Interval from 30 secs to 1 minute and problem has gone away (so far; one afternoon) and my path is back to WIDE1-1,WIDE2-2 to cover urban (Tampa) and country (Ruskin, Bradonton and remote highways). Hope it lasts. Thanks all for advice.
An extract of a msg from a local Digi sysop is quoted below:
"........But wait, here's your ]4+ posit yet again, not at 3702, oddly enough,
exactly another 179 seconds later.
So in the case of this one posit, it was heard 3 times with 179 seconds
between each of the entries into the intenet system, of course, with other
heard posits, it'd make you bounce around like a ping pong ball.
Suggestions:
1: Raise your beacon past 30 seconds. Even 40, but 60 would be the ideal
timing.
2: Make sure your radio's squelch is set so that it's not sitting on
packets for long, I've seen D700's sit on packets for 30 minutes if the
squelch is held open.
3: This one is a bit tricky. We need to figure out whos' sitting on
packets. It appears that any posit heard -direct- and not via a DIGI
behaved itself. That being the case, there might be an issue with a local
digipeater.
Without watching this real time from multiple sites I have access to on RF
as it's happening, and being able to do ping/queries to follow paths, it's
really hard to say exactly who's doing this, but there is indeed something
amiss."

Subject: [ui-view] Delayed Position Reports in Mobile situation
I am in the Tampa Bay area and have the following problem:
My mobile aprs station is picked up by a local (Seffner) I-Gate and placed ACCURATELY on the Internet as viewed thru UI-View. About 30 seconds later, another I-Gate station (Bartow) outside the local area places an OUTDATED location on the Internet and UI-View makes it look like the Mobile has moved back to an earlier position. This is very irritating to the people tracking me thru UI-View. It looks like position "bouncing" around.
I have gone from path of WIDE2-2, to WIDE2-1, to WIDE1-1, to WIDE, to NO path --- all with the same results.
Any advice, please.
