[aprssig] New IGate Operator

[Jim Conrad]

Hi Pete,

Thanks for the response. I understand the issue on saturation. I have 
set it up to only gate positions and with limitations. My thought 
process is that positions no matter the source of actual hams (not 
objects) should be reflected on RF which provides a coherent picture 
for the RF stations. At present there are only a few stations in my 
area using TCPIP. It also appears I am the only IGATE for a fairly 
large area. I monitor the RF side to make sure there is not any 
saturation (from my IGATE anyway).

The Microsat WX3in1 has settings to prevent such issues. It is quite 
a well thought out device The default setup is as follows;

APRS-IS to RF:
WIDE2-1
Gate if source station heard by heard via RF - No
RF Heard Buffer timeout 60min
Maximum packets per 1 min: 6
Maximum packets per 2 min: 9
Maximum packets per 3 min: 12

73
