[aprssig] Re: Why use this path?

[Robert Bruninga]

Appears no one reads the original HF.TXT when
operating APRS anymore.  This guy is absolutely
clueless.  He is violating every rule of APRS HF:

1) Never put anything more than 1 VHF hop
    after the gate.    (this keeps HF qrm from a 
    gateway to its own area, for local management)

2) Never use ECHO except in times of emergency
    or priority.  It just cuts channel capacity in HALF!!!

3) Never plan on going from HF to VHF and back

4) The only path ever receommended was VIA GATE,WIDE.
   These days, the correct equivalen is VIA GATE,WIDE1-1.

argh.... Bob

It's a clueless user on HF.  He's probably beaconing on 10.149 .    ECHO 
is the HF equivalent of "RELAY" .  "GATE" tells a receiving station with 
a dual-port HF/VHF TNC to retransmit the packet on VHF.   WIDE3-3 is the 
usual VHF path.  

The upshot of this is that IF the HF ECHO succeeds (and that is very hit 
and miss given the variable propagation on HF), he is then 
simultaneously entering numerous local VHF nets over a radius of 
1000-1500 miles (depending on HF propagation).  He is then creating 
needless QRM and clutter for a radius of three hops around each of these 
VHF entry points.  

The ultimate irony is that probably no one is even seeing him since most 
of the "victims" probably have their maps zoomed to show a city or 
county level area.  Thus a station from 500-1500 miles away would be way 
outside their map's view anyway.

Normally, if your goal is to be seen on findu,  you DONT NEED ANY PATH 
AT ALL on HF !!      There are numerous igate stations monitoring HF 
directly that will insert you straight  into the Internet system without 
cluttering dozens of VHF nets simultaneously.   And you will get there 
much more consistently than you do using long paths that just lengthen 
the packet and reduce the likelyhood of a successful decode.
