Manual for config.txt

[OE3KSS - Konstantin]

Hi Bela & Members!

 

I´m running DIXPRS on a Raspi and it is doing well. The setting of the main parameters was easy couse of the hints in the config.txt. For some settings my knowledge of APRS is to small. Is there a manual with more tipps for the usage?

 

The goals are:

• Fill-In Digi (WIDE1-1) for stationes of max. distance of 20km (our next digi ist out of order since 6 months :-( )
• Sending out messages for stationes with max. distance of 20km
• APRS-Igate
• Announcement of the Repeater used in our region

I hope you can help.

 

73!

Hi Konstantin,

• digipeater is not using distance filtering. WIDEn-n algorithm works properly for a fill-in digi, configure it to repeat WIDE1-1 only.
• messaging can use distance filtering, see config.txt however 20km seems to be too low
• Igate is OK, basic feature
• Announcement of repeaters and other object can is not built in but can be done easily with a small script, see previous mails on topic

Regards... Bela, HA5DI

Thank you Bela!

 

I´ll set the parameters as you said and post the file if there are questiones left.

Konstantin,

regarding sending objects (e.g. repeaters) you can find instruction at the DIXPRS WEB site:

Thank you Bela!

Sending objects should be no problem with a cronjob, but there are a few questions left:

I don´t understand this parts:

# Max number of digis passed for local stations
# Used as message gating condition for gating to Rf
# Default value is 2
# LOCALHOPS=1

# Filter; default is r/@/150
# @ is replaced with station position
# FILTER=r/@/100

----------------------------------------------------------------------------

Is this the path used when messages or the beacon are sent?

# Via used to send locally generated packets; default is WIDE1-1,WIDE2-2
#AXVIA=<lst>

-------------------------------------------------------------------------
What is this doing?

# Digipeaters processed with WIDEn-n algorithm; default is WIDE1,WIDE2
#WIDEN=<lst>

-----------------------------------------------------------------------
# Range value in miles, do not mix with PHG; no default
RNG=12

I filled the supposed range of the digi (RF) in - correct?
----------------------------------------------------------------------

This is my beacon text:

# Beacon text; %v replaced with actual version string; default is %v
BCNTXT=Pielachtaldigi [KSS/ICU]

On my rig(s) it is shown: A=001706Pielachtaldigi [KSS/ICU]

I don´t know where A=001706 is coming from.

-------------------------------------------------------------------------

These parameters i do not fully understand, but they are signed as experimental so i didn´t change anything:

# Gate locally generated frames to IS gateway; default is no
# Useful for rx-only radio ports
# Experimental, use carefully
#GATELOCAL=<y/n>

# Gate digipeated frames to IS gateway; default is no
# Experimental, use carefully
# GATEDIGI=<y/n>

Thank you for your support!

Hi,

messages gated from Internet to radio according to iGate specification to local stations which were heard on radio in the last 30 minutes and were not heard on the Internet in the last 30 minutes.

LOCALHOST is used to determine whether a station is LOCAL or not based on number of digis via it was heard. If you set it to 1, DIXPRS will not gate messages to RF if they are in 2 or more digis distance.

Filter command as in javaAPRS and compatible servers, see http://wa8lmf.net/aprs/JAVaprsFilters.htm for details. It used to filter which packets are send to DIXPRS by the server. DIXPRS is using it to find out which stations are available on the Internet. Bets is to use a distance filter. If value is too low, messages will be gated to RF even if stations on Internet, causing unneded QRM. If value is too high, it is causing unnecessary load on DIXPRS, but packages are not used. In general default filter is OK. You can reduce the disstance but be careful.

Regards... Bela, HA5DI

 Actually the APRSIS servers run an algorithm

that helps out IGates with respect to identifying which stations are on both RF and the Internet.  For example, if an IGate gates a station it hears on RF that is located 50 km away to an IS server, and the server also receives a beacon from that same station that was sent directly to APRS-IS via the Internet, the server will send that beacon to the IGate.  It does this regardless of what filter the IGate has applied to its login to the IS server.
