Problems with Winlink handshaking on VHF and no power to transmitter on HF

Dave Christensen
 

Two problems:
with ax25 started I do a wl2kax25 - k2wvc-10  (a gateway on 2 met4ers).  It connects but hangs after a Challenge is received.  Eventually it times out with jibberish and disconnects
Console output follows:
pi@kd7um-t2:~ $ wl2kax25 -c k2wvc-10

--------------------------------------------------------------
THE SECOND PROBLEM AS TO DO WITH NO HF AUDIO (AX25 STOPPED) on FLdigi, JS8Call, etc.
I can key the rig using FLdigi directed by the apps but I am not generating any power.  I ran measure_deviate.sh and it keys the rig AND gives me 30 Watts out which is what I expect.  I am using the Left audio jack for both packet and HF - at lease that is what the radio is connected to (IC-7000).
The "Power" control in both apps is at the maximum. Below is a screen shot of WSJTX configs:
 

pi@kd7um-t2:~/bin $ arecord -l
**** List of CAPTURE Hardware Devices ****
card 1: udrc [udrc], device 0: bcm2835-i2s-tlv320aic32x4-hifi tlv320aic32x4-hifi-0 []
  Subdevices: 0/1
  Subdevice #0: subdevice #0
pi@kd7um-t2:~/bin $

also touching any config parameter cause WSJTX to blow up and quit.  I am running WSJTX Version 2.1.0

What am I missing?  The apps both are hearing stations and they show up in the app display so hearing works and talking (on HF) doesn't
Thanks

I've checked in a script, ax_verchk.sh, that works similarly to how the
hf_verchk.sh script works for updating HF programs.

The ax_verchk.sh script checks the version numbers for ax25
lib/apps/tools in Lee Woldanski's ve7fet github repo and compares them
to Debian packages I built that live in the n7nix repo. After verifying
that the n7nix packages are current it then checks the installed
versions of these packages to determine if a new package install is
required.

Re: DRAWS and HF RMS GAteway possible ?

Basil Gunn
 

Thank you Bob NW8L for posting on the udrc forum!

Bob is the author of ARIM, Amateur Radio Instant Messaging,
(https://www.whitemesa.net/arim/arim.html) which works with ardop
(ie. piardopc & piardop2 on the RPi) ... and is a very nice piece of
work.

For me, at least, Bob NW8L & John G8BPQ are hero's of digital HAM radio
because they make their source code available!!

ardopc on github
https://github.com/DigitalHERMES/ardopc

Directory of John G8BPQ's downloads
http://www.cantab.net/users/john.wiseman/Downloads/

ARIM source code tarball
https://www.whitemesa.net/arim/src/arim-2.8.tar.gz

I suppose I'm a hero want-to-be because most code I have written in the
last decade is in a public repository ie. the source code is available.

With regards to Windows you can use an RPi & a DRAWS card by specifying
on your Windows machine either AGWPE or TCP/IP KISS to access the RPi
running direwolf. See the excellent Direwolf User Guide, thank you John
WB2OSZ.
https://raw.githubusercontent.com/wb2osz/direwolf/master/doc/User-Guide.pdf

You could also use the RPi & draws card as an ARDOP TNC & access it from
your windows machine with an IP address & socket port number.

As far as Windows goes I do not use it much (but I do use it). It's just
not that much fun to use. In terms of dollars/fun ratio you can not beat
a Raspberry Pi. I do not have a requirement of running Winlink Winmor
or Vara but I do have a requirement of running HAM digital mode
infrastructure that runs 24/7 on 12V. Easy and inexpensive to do with an
RPi & DRAWS HAT harder & more expensive to do with a Windows machine.

Anyway HAM radio is a hobby you should have fun playing with it and
Happy New Year to all the HAMS that read this forum.

Actually, ardop *is* open source. For Windows:

For Linux inc. Raspbian:

I want to build an easy solution for VARA.WINMOR and ARDOP.
Only one PC and one TRX. Therefore I am going with a windows based mini PC for less than 200USD.  Power consumption is max. 6W not an issue at all.
Then I am going to install either RMS Trimode or BPQ32.  Thats the plan so far.

Thank you for the information.  I have only ever encountered an executable package.

Re: DRAWS and HF RMS GAteway possible ?

Ryan Matthew Headley
 

It depends upon your goals.  A Windows machine is many times more expensive, and the power requirements are many times greater.  You also cannot leave a Windows machine running for months on end with no interaction and expect it to behave properly.

I should also mention that linBPQ running on a Raspberry Pi could access the ardop modem locally, and access Winmore and VARA modems hosted on a Windows machine on your local network.  That way if the Windows machine went down or you were unable to run it due to power requirements, your could still keep the ardop gateway up and running. 

Re: DRAWS and HF RMS GAteway possible ?

Roland
 

Going the Windows route for now.

Re: DRAWS and HF RMS GAteway possible ?

Roland
 

So it seems the easier way would be to go the Windows route and install Trimode.

Re: DRAWS and HF RMS GAteway possible ?

Ryan Matthew Headley
 

You can absolutely make this work with ardop and linBPQ if you are comfortable working outside or beyond the supported DRAWS image.  ardop is not open source, but it is free and can run on virtually any OS.  If you check the Winlink nodes, you will see that it is already quite popular.  With more people looking to run Winlink on something like the Pi as opposed to a clunky Windows computer, I only image that its footprint will grow.

As to how all of this applies to the DRAWS hat, it depends upon what your total desired use is.  The DRAWS will work extremely well as a soundcard for a Winlink HF node--and also provide you with GPS and a 12v power input.  In this particular application, think of it as replacing something like a Signalink, but with more features.

Thanks Bernard. The three lib/apps/tools packages are finished & I am
working on an AX.25 lib/apps/tools updater which should be ready
tomorrow sometime. I'll refresh the image after that. /Basil n7nix

Re: DRAWS and HF RMS GAteway possible ?

Basil Gunn
 

Can I use DRAWS Hat and a PI to run a *HF RMS Gateway* incl. VARA
,Winmor etc. ?
VARA & Winmor are closed source Windows only programs so will not run
on an ARM based RPi processor.

I believe the included Linux RMS Gateway is just for VHF/UHF AX.25 ....right ?
Linux RMS Gateway is open sourced AX.25 packet gateway.
I've been working on an ARDOP transport for paclink-unix or you could
run PAT or linBPQ32 to get ARDOP functionality.

AX25 over UDP is not working on #nw14

Bernard f6bvp
 

With NorthWestDigital radio Debian image nw14, AX25 over UDP is not working.

Although configuration is correct  there is no frames transmitted nor received via the axudp interface.

After reinstalling AX.25 libraries and AX.25 apps and utilities everything’s goes well.

Thus I want to encourage the NWDigital radio team to update the AX.25 stuff that may be wrongly installed or outdated.

Hi Ruben,

A month ago? Yes

You can verify just by looking at the board with a magnifying glass and comparing to the photo.

The yellow resistors will be marked 104 instead of 100.

We’re figuring out how the best way to handle the rework and will post once I return to the office.

Hi All,

If we are affected by the error, will we be notified? I’ve had mine about a month.

I’ve configured the software, but have not yet transmitted, everything works on receive. Getting antenna and go-box built to enable portable operation. The Pi-DRAWS case would be real helpful.

Also installing Auto-Access Point and WinLink PAT configuration by KM4ACK.

I can break them, but I can’t fix them.

100ohm Resistors we’re incorrectly Stuffed as 100k creating a 20dB attenuator.

I should have caught it when we had the cap problem.

With the new run, 8 Components were stuffed incorrectly:

C17, C20 (0603) should be 0.1uF but 10uF was stuffed

Easiest Fix is to Remove

R20, R21, R26, R27, R39, R40 (0603) 100ohms but 100kohms was stuffed

Easiest Fix is to solder 100ohms on top (in parallel)

Assembly has current stock in for re-work.

We’ll make it right for boards in the field, whatever it takes.

I’m out of the office until January 6th.
