Hi All,

I have Linux Mint 22.1 64 bit and installed QTTermTCP 64 bit version that I plan to run with Direwolf.

When I click connect nothing happens. I do have AGW configured.

Hello Jeff

If your platform is windows there should be no issue sharing a single sound device and a little more detail on your specifics may be required.

If it is linux then a custom .asoundrc file is typically required in order to share a single sound device with multiple apps especially in the case of VARA which requires wine or something similar on linux. Red has a nice summary you might want to look at here:

Although created with the RPI4 in mind this works equally well on x86 32 and 64 bit linux systems.

Master Communication has a audio splitter that shares audio between radio, signallink, and direwolf

I am stumped with trying to get both a Direwolf and VARA FM configuration to work.? I can get each to run individually but when I try to have them both work at the same time I can't figure out how to get the audio shared correctly between the two apps.? If Direwolf opens first it takes ownership of the audio device? leaving no choice to use in the VARA setup.? Am I trying to do something that can't be done?

So I've written a simple script to output the last x number of lines of the APRS log.? If I set the number of lines to 1 or 2 it works. I get "*** Connected to APRS" and the lines are shown.? But if I set the number of lines to 3 or more I do not get the connected message and no output at all.? No errors either.? It works when run from the command line.? Same issue if I use backticks and tail as well.? Any ideas?

#!/usr/bin/perl
use strict;
use warnings;
use File::ReadBackwards;

my ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) = localtime();
my $short_year = $year-100;
my $adj_mon = $mon+1;
my $log = sprintf "APRS_%02d%02d%02d.log", $short_year, $adj_mon, $mday;
my $path = "/home/doug/linbpq_rtg/logs/${log}";

sub tail {
?? my ($file, $num_lines) = @_;
?? my $bw = File::ReadBackwards->new($file) or die "Can't read '$file': $!";
?? my ($lines, $count);

?? while (defined(my $line = $bw->readline) && $num_lines > $count++) {
????? print STDOUT $line . "\n";
?? }

?? $bw->close;
}

tail($path, 2);

Using QtSoundModem 0.0.0.64 source compiled for x86_64 I see the following for a 40m port:

1:Fm KT4WO-1 To KB9PVH-6 <RR C? P R0>[15:50:43R][--+--][AX25 0]
1:Fm KT4WO-1 To KB9PVH-6 <RR C? P R0>[15:50:49R][--#--][MEMAX25 0]
1:Fm KT4WO-1 To KB9PVH-6 <RR C? P R0>[15:50:55R][--+--][AX25 0]
1:Fm KT4WO-1 To KB9PVH-6 <RR C? P R0>[15:51:01R][--#--][MEMAX25 0]

The obvious difference is the # vs + which may well explain things but I plumb forget what the difference is at the moment without digging into the source. What does MEMAX25 indicate?

FWIW this instance of qtsm is configured with bit recovery and il2p set to NONE and FX25 set to RX+TX.

Hi Mark,

I figured it out. I hadn't beaconed to APRS-IS (I'm not ready to advertised my node just yet, still have a few tweaks to make) so APRS-IS could not understand my filter of m/200.? It has to know where I am for that to work. So I changed the filter to r/44/-64/200 and now it is feeding me all kinds of data.

As for the freq I am on I have no intention of broadcasting any APRS over RF.? The setup I have is just to capture any RF that someone else may broadcast, an unlikely scenario but still a possibility.

73,

Doug

I can't give you anything definitive but I can offer a couple of things to try...

First thing I noticed is that your APRS call is the same as your node call.? I've never done that and don't know if it will work or if it presents a conflict.

Then, your APRSPath and Digimap uses port 1 on your node, which is a VHF radio on 145.09, a packet frequency.? 144.39 is the APRS frequency.? Try putting your radio on 144.39 for a while and monitor traffic.? You will likely start seeing traffic.

You obviously connect to the APRS servers but it was my understanding (although I might be incorrect in my thinking) that the APRS-IS servers were to upload your data.? You will not receive anything from them.

And last, the APRS location database has no record of VE1LG-7 for the last 24 hours.? Have you looked to see if BPQ is reporting any errors at startup?


That's what I see at first glance. Since I do not use APRS on BPQ (I use JAVAprsSrvr for APRS) I cannot help much beyond those comments.


Good Luck
Mark

Thank you, sir.

I want to receive from APRS-IS (but no IS to RF) and gate any RF to IS.? With the config below I am connected to APRS-IS but don't seem to be getting anything from it.? Passwords below are fake of course.? Not that one can't easily determine a qualifying APRS-IS password.

I have done this before so that I don't have to add 32 bit support in
Xubuntu, but I don't remember what dependencies were missing in a
fairly typical Ubuntu installation. I remember it was about 3 or 4.
Does anyone know of the top of their head wha they are?

I know if I connect from my node to another using S then when I "bye" from that second node I am returned to the first.? But I can't seem to get this working for applications.? In my bpq32.cfg I have the following from CMS (which is otherwise working well):

APPLICATION 2,RMS,C 10 CMS S,VE1LG-10,KINGRMS,255

Yet when I issue bye from CMS it disconnects.? This is in QtTermTCP via telnet to my node, not over RF, if that makes a difference.

Also, how would I add S to the BBS when it doesn't use C as so:

APPLICATION 1,BBS,,VE1LG-1,KINGBB,255

Cheers,
Doug

Hmm, that's an interesting thought.? I keep wanting to blame individual Pi's but the ones that keep eating SD cards for lunch (and breakfast and dinner!) are also the ones on a multi-way USB power supply rather than their own individual supplies.? And I think one of those got moved to its own dedicated PSU when the UPS 'brick' went in, and hasn't eaten a card since.

AXIP over Starlink should work fine but it uses CGNAT which means you won't be able to use traditional port forwarding.

That said If one side of the link has a public IP or can port forward and you have keep alives enabled it should work.

You could also use a VPN or Zerotier like Scott suggested

Hi Scott - just recently got notice that we could get on their "best effort" service until they're 100% happy with the coverage that we could move to "residential" service.? Trying to work out if we pull the trigger now or wait a bit.? Please keep us posted ss to your experience.?

Right now I'm on fixed wireless through Frontier Communications.? I'm using noip.com DDNS service for the node address.? Currently I have no problem with port forwarding through their router or the Orbi mesh that's behind it, but my understanding is that this will change with Starlink.
