I seen her walk across my Mac keyboard and the Windows machine keyboard was right next to it. So I figured she managed to hit the Windows one too. Not the first time that has happened though. I can usually repair anything she does, but not this time....lol.

Thanks All.

With the Frequency Monitor window visible, try unchecking the checkmark.  Or right click in the window and disable it from there.

Re: Two way igate not working.

Yes the FTM400 without an external TNC is receive only.  But with a TNC or some other interface it becomes just like any other radio. I’m not relying on it’s aprs modem.

That would be true if he was using an FTM-350 type port, but he's got a KISS-mode TNC3 connected via audio to the radio if I read the screen shots correctly.  That was EXACTLY my first thought until I looked more closely at his text and his pictures.

Re: Two way igate not working.

Lynn Deffenbaugh
 

I assume you're looking for messages to gate from -IS to RF, not arbitrary packets.  With that said, APRSIS32 will only gate a message for a station under the following conditions:

1) The APRS-IS feed delivers such a message to APRSIS32.  This SHOULD be automatic if you're connected to 14580 on an APRS-IS server that is consuming a full feed on the other end and IF the following conditions have been met.

2) A packet has been received from the station addressed in the message "recently" and "near enough".  You can see which stations meet this criteria if you do a View / None followed by a View / RF / Local.  Any station that shows up there are eligible to have messages gated to them.  Or you can send a ?APRSL message which will respond back with a list of stations which are considered "Local".  Yes, you can send this message to yourself in your APRSIS32 IGate instance.

I believe there are several Trace Logs that can provide additional information.  Look for logs called IGate and IGate(NOT), especially the latter as it will show why a message was NOT gated to RF.  Bring up the Trace Log and ensure that you have Enabled it and THEN try getting a message to a local RF station from the APRS-IS.

BTW, the way I usually test is with an HT, I'll send a message to "ISS" (without the quotes) and see if I get the auto-response back.  If you're not familiar with the SATSRV, read http://aprsisce.wikidot.com/doc:satsrv

Or send an APRS station ID (callsign-SSID like KJ4ERJ-12) to "QRZ" (again without the quotes and see what comes back.

Did I test it?  Yes, that's why I mentioned that you could test it yourself if you used APRSIS32 which includes a filter test capability, but only in a positive sense.

READ the definition of the s filter from the quoted page:

s/pri/alt/over

Symbol filter

pri = symbols in primary table (| => /)
alt = symbols in alternate table (| => /)
over = overlay character (case sensitive)
For example:

s/->     This will pass all House and Car symbols (primary table)
s//#     This will pass all Digi with or without overlay
s//#/T   This will pass all Digi with overlay of capital "T"

Note that PRIMARY table symbols go after the first FORWARD slash and alternate table (ones that can use overlays) go after the SECOND slash and the overlays go after the THIRD slash and are CaSe SeNsItIvE.

So, if we look at one of the stations you want to get rid of, say N7LOB-10 at http://aprs.fi/N7LOB-10 and then click on the Raw Packets link, we see that they all come from WINLINK and look like:

But APRSIS32 makes this easier by showing:

N7LOB-10
1200 R5m Winlink Gateway

Freq: 145.630MHz
Sym: WinLink (Wa)
App: WinAPRS, etc (L2K)

WINLINK->TCPIP*

Note that the symbol is Wa.  This means alternate table (since the first character isn't /) symbol a with an overlay of W.

Finding one of the DSTAR objects is a bit trickier since they have an embedded space, but if you search for KB7ZEN* in aprs.fi's Raw Packets display, you get:

Which APRSIS32 kindly describes as:

KB7ZEN B
440 Voice 438.50000MHz +0.0000MHz

Sym: DARES (Da)

App: D-Star Gateway (01)

2020-03-07 12:09:50 (19m24s)
KB7ZEN-S->TCPIP*

Which is the same alternate table a symbol with an overlay of D.

So plugging alternate table with overlays D and W into the formula for the s filter, we get:

s//a/DW

When I put that filter into an APRSIS32 Filter Test window, I get LOTS of packets including:

Which kindly tells me that packets were hitting on both the D and W overlay characters which is confirmed if you use the aprs101.pdf to visually parse the packet data and find the symbol and overlay characters that match.

Which you can see (if you've studied aprs101.pdf and can visually parse packets) includes both the D and W overlays of the alternate table a symbol.

So, yes, I've tested the recommended filter in the positive sense.  Testing a negative filter is much harder in that you have to go through a large (I use planet-wide) stream of data and determine that the target packets are NOT present.

So, my challenge to you is did YOU apply and test the negative form of the filter properly?  What makes you believe it "did not work"?  Is it possible that it DID work and SARTRACK is simply displaying stations that it heard before the negative filter was applied?  Did SARTRACK truly apply the negative filter to the upstream APRS-IS server connection?

And if you need help confirming those questions, please inquire on the SARTRACK support list as they are not APRS-general questions.

PS.  An alternat esymbol to get rid of all packets from WinLink would be -b/WINLINK or -u/APWL2K.  For the DStar gateways, you could use -u/APDG* or -u/APDG01/APDG02.  The trick to filtering APRS-IS is to deterine what common feature is shared by the target stations' packets and NOT shared by desired station packets.

Since the diamond is red should it use the \a and not /a?

 

 

-s/\a/DW

 

Thank you.

Nice map, but I don't think that's APRSIS32...  If it was, you could test the positive filter with Control-G for a filter test.  But here's what I think you need:

-s//a/WD

Yes, there's 2 slashes after the s and one slash after the a.  It says to suppress all "a" symbols from the alternate table (the red diamond) with an overlay of W or D.

-o is an object filter which is based on the object name.

I suspect you're looking for a -s filter which is a symbol filter.

Please give me a few of the stations you'd like to not see so that I can verify exactly which symbol they're using to build you a suitable -s/ symbol filter.

Greetings Lynn,

 

This is an awesome description! I have always had trouble wrapping my head around testing filters. I usually end up with what I want but it takes a while!

Did I test it?  Yes, that's why I mentioned that you could test it yourself if you used APRSIS32 which includes a filter test capability, but only in a positive sense.

READ the definition of the s filter from the quoted page:

s/pri/alt/over

Symbol filter

pri = symbols in primary table (| => /)
alt = symbols in alternate table (| => /)
over = overlay character (case sensitive)
For example:

s/->     This will pass all House and Car symbols (primary table)
s//#     This will pass all Digi with or without overlay
s//#/T   This will pass all Digi with overlay of capital "T"

Note that PRIMARY table symbols go after the first FORWARD slash and alternate table (ones that can use overlays) go after the SECOND slash and the overlays go after the THIRD slash and are CaSe SeNsItIvE.

So, if we look at one of the stations you want to get rid of, say N7LOB-10 at http://aprs.fi/N7LOB-10 and then click on the Raw Packets link, we see that they all come from WINLINK and look like:

But APRSIS32 makes this easier by showing:

N7LOB-10
1200 R5m Winlink Gateway

Freq: 145.630MHz
Sym: WinLink (Wa)
App: WinAPRS, etc (L2K)

2020-03-07 11:59:16 (18m54s)
WINLINK->TCPIP*

Note that the symbol is Wa.  This means alternate table (since the first character isn't /) symbol a with an overlay of W.

Finding one of the DSTAR objects is a bit trickier since they have an embedded space, but if you search for KB7ZEN* in aprs.fi's Raw Packets display, you get:

2020-03-06 21:42:10 EST: KB7ZEN-S>APDG01,TCPIP*,qAC,KB7ZEN-GS:;KB7ZEN B *070242z4656.40ND12236.00Wa/A=000010RNG0001 440 Voice 438.50000MHz +0.0000MHz

Which APRSIS32 kindly describes as:

KB7ZEN B
440 Voice 438.50000MHz +0.0000MHz

Sym: DARES (Da)

App: D-Star Gateway (01)

Time: 00-07 12:09:00z
2020-03-07 12:09:50 (19m24s)
KB7ZEN-S->TCPIP*

Which is the same alternate table a symbol with an overlay of D.

So plugging alternate table with overlays D and W into the formula for the s filter, we get:

s//a/DW

When I put that filter into an APRSIS32 Filter Test window, I get LOTS of packets including:

Which kindly tells me that packets were hitting on both the D and W overlay characters which is confirmed if you use the aprs101.pdf to visually parse the packet data and find the symbol and overlay characters that match.

Further, if I telnet to my local friendly APRS-IS server and set up that filter (see http://www.aprs-is.net/Connecting.aspx for instructions), I get the following packets:
