[aprssig] More Rampant Cluelessnes on HF WAS:Why use this path?

I have been monitoring 30 HF APRS for some time now from my QTH in 
Pasadena, CA.  
     http://wa8lmf.dyndns.org:14439    

is a UIview-generated display of what I am hearing using a horizontal 
dipole made from two  30M  Hamstick mobile whips at about 20 feet AGL 
connected to a Kenwood TS-50 and KAM-E TNC.    I have watching symbols 
appear on the map for about a year now.  but just recently added 
AGWmonitor to the setup so that I could see the raw packets behind the 
symbols.  I was shocked at the percentage of clueless packets being 
transmitted.

The strings below are as monitored in just the last few hours here. All 
are cut and pasted from the AGWmonitor log for my KAM HF port :



2:Fm K1PIG To ECHO Via N5NGN*,WIDE3-3,ECHO,GATE,WIDE3-3 <UI pid=F0 
Len=30 >[18:48:35]
<IGATE,MSG_CNT=218,LOC_CNT=92

    [[ The station discussed earlier monitored clear out on the west 
coast!  An even more totally insane useless path!  At least the 
incorrect use of WIDE3-3 on the HF side guarantees this packet will only 
go one hop and never get a chance to abuse the VHF side....   ]]




2:Fm K7PW To APU25N Via APU25N,GATE,WIDE2-2,WIDE2-2 <UI pid=F0 Len=54 
 >[18:53:56]
=3301.96N/09708.77W&Flower Mound, TX Gateway {UIV32N}

      [[A digi with the call APU25N????    Fortunately this path is dead 
on arrival and will never get a chance to abuse 4 hops on VHF!  This 
stupid path just makes the packet longer and less likely to be received 
at all.... ]]




 2:Fm W1UP To APR867 Via WIDE,WIDE <UI pid=F0 Len=64 >[18:58:43]
=4245.07n/07145.88W-PHG5230 Jim-Mason, N.H. - FN42cr - Icom 718

       [[ Another DOA packet with a totally useless path! ]]


 
 2:Fm VE4GN To APW272 Via ECHO <UI pid=F0 Len=21 >[19:03:03]
 >210912 ve4gn at rac.ca

 2:Fm VE4GN To APW272 Via ECHO* <UI pid=F0 Len=21 >[19:03:07]
 >210912 ve4gn at rac.ca

      [[ I heard this guy from central Canada direct here in southern 
California, and then again moments later via a totally unneccessary HF 
"ECHO" ]]




2:Fm WA9AWG To APU25H <UI pid=F0 Len=48 >[19:09:23]
 >271207zwa9awg at hotmail.com Patronville, Indiana

       [[ At last someone with a clue about HF settings! ]]



2:Fm K5RAV To ID Via GATE,WIDE <UI pid=F0 Len=42 >[19:57:04]
K5RAV/R ECHO/D GATE/G K5RAV-1/B K5RAV-7/N

      [[ Huh???   ]]





2:Fm KM5HG To APU24 Via ECHO,GATE,WIDE1-1 <UI pid=F0 Len=62 >[20:17:40]
@300316z3615.56N/09542.20W_010/000g000t072r000p000P000b10093\

 2:Fm KM5HG To APU24 Via ECHO*,GATE,WIDE1-1 <UI pid=F0 Len=62 >[20:17:43]
@300316z3615.56N/09542.20W_010/000g000t072r000p000P000b10093\

 2:Fm KM5HG To APU24 Via ECHO*,GATE,WIDE1-1 <UI pid=F0 Len=62 >[20:17:45]
@300316z3615.56N/09542.20W_010/000g000t071r000p000P000b10093\

      [[ A demonstration of  HF channel abuse through unneccessary 
digipeating!  The original beacon was heard direct over a path of 1000 
miles!  Apparently two different HF "ECHO" digis repeated this packet 
after the original direct transmission wasting THREE  time slots on the 
low-capacity 300 baud HF channel.  ]]




2:Fm KF5ET-4 To APU25N Via WIDE1-1,WIDE2-2 <UI pid=F0 Len=30 >[23:30:09]
<IGATE,MSG_CNT=218,LOC_CNT=78

       [[ Perfect compliance with the New Paradigm VHF path settings. 
However it won't do squat on HF! ]]   



2:Fm MISION To APN390 Via WIDE,GATE*,WIDE <UI pid=F0 Len=65 >[15:01:00]
!4716.44NN12024.38W#PHG6860/WR7ADX WA MISSION RIDGE WX APRS WIDE


       [[ I see this station from central Washington all the time on HF 
producing a N-n green digi star on my HF map.  Apparently someone one 
hop away on VHF is reverse-gating MISION's  VHF beacon onto HF where the 
second WIDE then does nothing.   ]]
