Since getting the IGATE online a few weeks ago I have been monitoring the
RF congestion. My IGATE has not considerably impacted the area
throughput. The WX3in1 generates a fair amount of statistics to track
usage and issues. It appears that I am the only IGATE in the area looking
at the paths and I don't have great coverage since my antenna is only at
20ft. Most of my gating (RF to IS) is via better coverage DIGIs in the
area. As an example in the last 12 hours my IGATE has gated 1521 RF to
APRS-IS packets but only 30 APRS-IS to RF.<br class=""><br class="">
I have seen the TCPIP devices rapidly report positions you mention (think
one of the offenders was some type of IPhone app) looking at the raw
packets that APRS Direct logs. One of the reasons I changed my IS to RF
filter down to 2 max packets per 1 min, 4 per 2 min and 6 per 3 min to
prevent a flood to/congestion of the RF side.<br class=""><br class="">
If you are interested in reading about the WX3in1 it's made by a company
in Poland called Microsat. Sold in the US by HRO and RPC. Links below
provide info, Microsat has a facebook page and a webpage for support.
Currently there page indicates that there are 867 active WX3in1's on the
air in the world. Device and the accessories etc are very impressive and
not that expensive considering the capability. The units construction
quality is excellent. Default settings with minor changes (callsign,
network etc) make getting the station online rather quickly. Been
involved in APRS for a while but never as an IGATE or DIGI so I am
learning quite a bit as I go.<br class=""><br class="">

I can see the benefit with respect to messaging. Someone on RF could see
someone on a phone, and send them a message.<br class=""><br class="">
There was a bug in AprsDroid a while back (now fixed as far as I know)
that resulted in stations sending positions very rapidly, so there is the
risk of gating an Android device running an old version.<br class=""><br class="">
IMO it all depends on RF traffic in a local area. If it's very low, it
should be OK to RF gate the phones, especially with rate limiting
functionality in the Igate. How low is low - yeah, it's subjective.
Whether the device in question can do it is really a question for the
maker of that device - does it have its own mailing list?<br class="">

<dd class="">Now for non-APRS RF resources that may benefit by being announced on
APRS, which what you may be headed toward, look at Bob's info here:Â

I have to admit I haven't looked at that yet; thanks for sharing.Â
