[Xastir] Kantronics DiGi help

Hello Danny,

For the EC0CK-1 digi, what paths do you want it to support?  WIDE1-1 
only?  WIDE2-1 and WIDE1-1 only?

Next, can you send us a copy of the packet string that the EX0CK-10 is 
beaconing out that you're hoping to see on APRS.FI (via EX0CK-1)?  You 
can use various tools to inspect your string to make sure it's ok such as:

    #example from 
https://aprs-python.readthedocs.io/en/stable/parse_formats.html
    #
    sudo pip install aprslib
    python
    import aprslib
    aprslib.parse("FROMCALL>TOCALL:!4903.50N/07201.75W-Test /A=001234")
    quit ()

> 1 APN382 VIA WIDE2-2
> 2 APN382
> 3 APN382
> 4 APN382

These look wrong as I would expect this to be "APN391" for your KPC3+ 
v9.1 TNC.  Seems you mistakenly cut and pasted from a different TNC.


> MYCALL   EX0CK-1 0

Why is there a space in there?   You should read the recommended APRS 
configuration setup from WB4APR - 
http://www.aprs.org/kpc3/kpc3+WIDEn.txt .  Specifically, you ideally put 
a LOCATION name in there like "BISHKEK"



> MYALIAS  WIDE1-1

This is wrong.  Per the above URL, set this to something useless like NONE


> MYDROP   0
> MYNODE   EX0CK-1 0

Why is there a space in here as well?


> PACLEN   0

Not sure why you overrode the default of 128 bytes here though I don't 
think it will hurt you


> TXDELAY  18

Are you sure this is enough time for your radio to key up?  Until you 
get things working 100%, I would recommend to set this to something 
conservative like 30  (aka.. 300ms)


> UIDIGI   ON WIDE1-1

Are you sure you don't want to support WIDE2-1 as well?
