Re: RFI issues with RPi3B+
I still to try the Fe-Pi clone hat, but bought a cheap Sabrebt (one with volume control on it and you can turn headphone and mic off by buttons). Have four cheap Sabrent USB audio, plus this one now. No Linder having any RFI issues. Might just continue using Sabrent witty controls. I like that just a push of button can turn iGate off or difioeater off, while keeping other running.

Also, found this USB audio adapter in one of my junk drawers that I totally forgot about. If picture can¡¯t be posted here, it¡¯s one of those USB audio adapters that has about a 4¡± USB cable, then has a volume dial on the adapter itself, plus buttons turn on/off the speaker or microphon independent. It¡¯s working and is kind of cool because it¡¯s another point to adjust volume (found it works well to use dongle knob to make fine adjustments), plus the button switches are pretty cool if you, say, want to turn off the digipeter but still have iGate running (or vice-versa). Found my RFI issue really wasn¡¯t much of an issue anyway now that I¡¯m connected to an outdoor antenna (Diamond V2000A). Very cool. I¡¯d say with the dongles, it¡¯s seems about 99% solidrbut expect with a hat it to be 100^. :-)

Fred,
I know you've done the hard yards and it's
working for you but you may
still find this page about gpsd interesting.
FWIW I ran into the same 2D/3D problem as you
but I can't remember which
(RS232) GPS (Garmin 18 series or older Ublox)
I used at the time. I
ended up compiling GPSD from sources to get
an updated version. But this

Define "GPS has been running for at least a day". By default,
your GPS puck won't be activated by gpsd and start listening for
GPS details until it has a listening client like direwolf, cgps,
gpsmon, etc. This seems to be a default for minimizing power
consumption. The gpsmon tool doens't show how long it's been

Re: Repeating "GPSD: Location fix is now 2D/3D"
A lot of conversation about the PPS. I am pretty sure ths conversation was about getting position infomration through gpsd, not time (beyond the data stamp).
I have no idea how a Garmin GLO2 could implement a PPS - its Bluetooth.
Is this just additional commentary for tose using gpsd for more than position?
? I don't see anything on PPS in the Direwolf manual. ? I am not sure how Direwolf benefits from a PPS?
Not trying to be critical, just checking if I missed something.

Fred,
I know you've done the hard yards and it's working for you but you may
still find this page about gpsd interesting.
FWIW I ran into the same 2D/3D problem as you but I can't remember which
(RS232) GPS (Garmin 18 series or older Ublox) I used at the time. I
ended up compiling GPSD from sources to get an updated version. But this
was near enough to two years ago.

Re: Repeating "GPSD: Location fix is now 2D/3D"
Hi Fred,
Both my Ublox devices - LEA4 (IIRC) and a considerably newer M8 - have 1PPS so yours likely does too. The Garmin I dabbled with was the 18-5Hz with sentences sent five times per second for better positional accuracy but its PPS seemed to not play nicely with gpsd. Either that or I wasn't smart enough to make it happen! I cut my losses and bought the M8 board for the RPi4 for my Stratum 1 network time server.
Take care
Regards

GPS has been running for at least a day.
Define "GPS has been running for at least a day". By default,
your GPS puck won't be activated by gpsd and start listening for
GPS details until it has a listening client like direwolf, cgps,
gpsmon, etc. This seems to be a default for minimizing power
consumption. The gpsmon tool doens't show how long it's been
running with a 3D fix but cgps does.
The GPS has had a device connected to a device. It supports 4
different devices. One device is the same RPi Direwolf is running
on but is an terminal window on my PC with /cgps /running. Now a
second device (PC/u-center) is connected.

Re: rPi 4 / Signalink USB / Yaesu ft-895 / Direwolf.
Thanks David. Are you by chance on Discord?? I'd love to chat about options. I'm not trying to get the KPC back into the stack.
I just want the rPI to run direwolf and then find a good client that I can hit from on the LAN.
My primary use case is to use commands like?
C EOCND?- to hop from node to node in our Marin Country packet network, and open corresponding MBs (mailboxes - these are usually hosted on old school TNCs)
I also want to be able to access the Digipeater on ISS. I can see the traffic when it goes overhead, but no way to upload.
I'm going to be on this google Meet video chat for ten minutes in case you care to help out "in person"
Hello Nick,
I have a KPC3+ in the garage.?
But as you suspect ,I'm hoping to use Direworlf/Raspberry pi as
a low level TNC, and then access it over the local area network
via port 8000 or 8001.
You can definitely access Direwolf via port 8000 and 8001 for AX.25
services but a KPC3 cannot do this alone.? There are ways to
integrate a KPC3+ with Linux and add on AGW support with the ldsped
program but it's still going to be less-optimal.
I've tried linpac on the pi, but it doesn't seem to set up
properly. I need to know a full heirarchical addresss for my QTH
which I can't seem to find.
I can help you with Linpac since I'm the maintainer but you can
technically put anything there as long as it "looks right".
The rest of my computers are Macs. All the TNC/AGM clients seem
to be for Windows.
Ok.. and don't forget that Direwolf natively runs on Mac as well.
Does anyone have any ideas?
WINE also runs on the Mac too.

Re: rPi 4 / Signalink USB / Yaesu ft-895 / Direwolf.
Hello Max,
KPC3+ TNCs are probably one of the best hardware TNCs out there
but Direwolf has better packet decodes than it.? They are pretty
good for a "set it up and forget it deployment" but their
functionality for a PBBS is pretty low, they haven't received any
real fixes or improvements in a decade or more though there are
known bugs with them, etc.
I suppose they are a good choice for some but a Direwolf setup +
some other software will always blow it away.
Ps.? If you're just pining for a classic TNC2 like interface, you
can run BPQ32 with it's TNC2 emulator + Direwolf to effectively
get you the same experience.

Direwolf is a TNC intended to provide lower level set of tools for
APRS but it also offers extensive connectivity to OTHER TOOLS using
KISS, TCP-KISS, AGW, etc. to support things like terminal programs

Re: rPi 4 / Signalink USB / Yaesu ft-895 / Direwolf.
I have used AGWTermTCP and connect to Dire Wolf through an AGW port for testing. It seems to have the features you are looking for.
Also, having AGWMonitor running is helpful can be helpful when troubleshooting as well.

Re: Repeating "GPSD: Location fix is now 2D/3D"
Fred,
I know you've done the hard yards and it's working for you but you may still find this page about gpsd interesting.
FWIW I ran into the same 2D/3D problem as you but I can't remember which (RS232) GPS (Garmin 18 series or older Ublox) I used at the time. I ended up compiling GPSD from sources to get an updated version. But this was near enough to two years ago.

Hi David,
Thanks for the update and how strange if this was a gpsd thing.? What version were you running before?
Version 3.17
Gary¡¯s comment: Wow, that is 4 years old.? You need to update that.? 3.23.1 is current.
I am not sure but came from the apt repository. I didn¡¯t install gpsd initially on this RPI. I wouldn¡¯t have done a build from source.
Do you know what was the specific fix in the newer GPSD that resolved your problem?
Sorry I don¡¯t.
Best regards,

Problem has been resolved. I now get a solid 3D fix.
The solution: update to the latest revision of GPSD. Revision 3.23.1
As background, I have a Garmin GLO 2 which will support up to four
users. A similar unit is the Dual XGPS160. I have used it in the
past for an Android tablet with the hopes of also sharing with an
RPi. Currently, The tablet, RPI and my PC are receiving data.
I was asked why I would use a GPS like this. When running multiple
RPIs, which may not have sky view, a GPS with a view can share
with each.

GPS has been running for at least a day.
Define "GPS has been running for at least a day".? By default,
your GPS puck won't be activated by gpsd and start listening for
GPS details until it has a listening client like direwolf, cgps,
gpsmon, etc.? This seems to be a default for minimizing power
consumption.? The gpsmon tool doens't show how long it's been
running with a 3D fix but cgps does.
The GPS has had a device connected to a device. It supports 4
different devices. One device is the same RPi Direwolf is running
on but is an terminal window on my PC with /cgps /running. Now a
second device (PC/u-center) is connected.
What constitutes a ¡°very good¡± lock?
That's evidently a huge topic in itself and is well outside the
scope of this Direwolf.? I did a search for "gpsd 3d lock" and
this hit seems like a good start:
<>
A key point in that article is that though your system lists it's
using X satellites, it doesn't mean it's hearing them well.? This
can be due to local RF interference, etc.
I can see I have a 3D position all the time now that my Windows PC
is connected. I am aware of the FIX differences and how everything
can affect the satellite signal; trees buildings, angle of
antenna, etc. Not being snarky! If this was a serial GPS or a
USB-GPS (serial?) there would be no BT layer and for serial, using
/dev/ttyS0 would be correct and USB would be similar. Based on an
exchange with Robert KB8RCO it seems this maybe the case here. If
may be that each of the four possibilities need /dev/ttys0-3? In
the end, I will have learned a little more.
This is what I get when running /gpsmon/. Any clues there?
More information is available in cgps but there are other tools
available to troubleshoot GPS issues such as gpsprof but I've
never used them.? Ultimately, I don't think your issue is with
Direwolf.. it's going to be somewhere in the GPS into GPSD area.?
I would start here:
<>
I will certainly check this group. From my PC experience on
needing to actually connect to a COM port, I wonder if a RPi
¡°comport¡± must be connected as well. Robert, KB8RCO, suggested
something regarding auto-connecting at reboot but I haven¡¯t chased
that since the basic connection is not functional yet.
Thank you!
