When I last looked at the Yaesu FT-817 over a year ago I had to
disconnect pin 6 on the mDin6 cable which controls squelch on that radio
to get receive audio to work.

See Running FLdigi with the Yaesu FT-817 at this link:
https://github.com/nwdigitalradio/n7nix/blob/master/docs/RADIO_APP_NOTES.md

Also run the measure_deviate.sh script to verify transmit as previously
described.

Basil, yes I reimaged the micro sd card. The rPi otherwise is
functioning normally. To be clear, I haven’t tried transmitting. When
I monitor I’m not getting evidence of signals ( which I can hear ) on
the screen. I had been using left minidin. Switched to right in draws
manager, same result. I selected preset for ft 817 af. Audio in out in
wsjt plughwCARD=udrc, DEV=0. Rick

A basic test is to use the measure_deviate.sh script
https://github.com/nwdigitalradio/n7nix/tree/master/deviation

This will generate a tone and enable PTT. There are options to test left
& right channels.
Use a second radio to hear the generated tone.

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

Basil,

 

Thanks for refreshing my memory with the link below – it had been a good while and my focus has been significantly elsewhere since before Dayton/Xenia last year:

 

In a previous post it was mentioned that the contents of that email were captured here:

https://github.com/nwdigitalradio/n7nix/blob/master/docs/RADIO_APP_NOTES.md#alsa-settings-for-ic-7000

Again my very faulty recall was that I did test these settings and found that it still did not allow me to adjust the ALC to the “nil” reading for minimum sig distortion without the noise issue cropping up. OTOH, I am pretty sure I used the discriminator output for receive… but RX was never the issue here. Since I have not tried the new image, I will give it a go and configure from the ground up. If that can be made to work well, then I’ll tackle the 7100 to see if it is different.

 

Thanks,

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

Basil Gunn
 

I believe Basil did experiment with his friends IC-7000, but if I recall
correctly, only determined that the FM output could be made to work, but I
can't remember if he actually took a crack at the fldigi/wsjt-x over HF
problem and was able to duplicate it.
You recall incorrectly. Below is the link to email sent after we
successfully set up an IC-7000 for FLdigi Olivia 8-250

https://nw-digital-radio.groups.io/g/udrc/message/2523?p=,,,20,0,0,0::relevance,,%23ic7000,20,2,0,28894545

Ignore this remark as the udrc/draws driver is now in mainline linux kernel.
"You must use the latest udrc-dkms driver (1.0.5)"

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

Corky Searls
 

Just FYI, indeed Fldigi and the WSJT-X and JS8Call apps have very different sound sensitivities. On my main HF system which is still using a laptop with a SignaLinkUSB to drive a K3 I find I need to significantly change either the audio output levels for the computer, or in my case I change the Mic gain on the K3 (the change is about 10 units).

In talking with others, this appears to be "normal."

Thanks and 73,

Re: Nixtracker

Basil Gunn
 

remark; updown_log.sh, line 8, log_updown.sh -> updown_log.sh I
believe.
Changed comment to be consistent with actual name of updown_log.sh
script.

question; same file, lines 14-18 give the crontab entries. I had to
add ‘root’ as user to those lines like the other lines in /etc/crontab
in order to get lvd shutdown working. I’ve seen this before when you
were teaching us how to use btest.sh and crontab to beacon. Again, no
‘root’ Or any user specified in the crontab lines you wrote. It makes
me wonder if I am messing with the wrong crontab file? Pardon my
ignorance.
The comment in updown_log.sh has a crontab example which points to the
/home/pi/tmp directory. This is wrong & only used for
development. Changed the example to use the local bin directory
/home/pi/bin and updated bin_refresh.sh script to include the tracker
updown_log.sh script.

See commit here:
https://github.com/nwdigitalradio/n7nix/commit/9d65bb812bb699df3627be01a52abe0ad953c09d

To update:

cd
cd n7nix
git pull
cd config
./bin_refresh.sh

You shouldn't have to be root to run the the updown_log.sh
script. ie. the crontab should be used by default user (pi).
You can test this out by running the beacmin.sh script and verify that
it doesn't return with an error. You are confirming that the 'beacon'
command does not need to be run as root.

cd
cd n7nix/debug
./beacmin.sh

I tested this on my bench & it looks ok. Later on this afternoon I will
pull the mSD card from my truck & verify.

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

Jack Spitznagel
 

Dave, Basil, All,

 

Apologies, I probably should have retitled this message to call out the problem with the IC-7000. I do not want to hi-jack the original thread, but it is worth continuing the HF element of it.

 

If you look back about a year ago in the archives, you’ll find that I reported exactly these “symptoms” with my IC-7000 using both of my DRAWS boards (one is an “early-early” adopter board, the other is an early adopter board). With both boards, my FT-817 works fine with HF programs. Both a RigBlaster and a SignaLink will drive the IC-7000 without these issues even though the settings are a little touchy because the audio drive level has to be turned way down.

 

I have copied Dave’s settings below because they agree with my findings. As Dave discovered, tremendous amount noise is introduced as the DRAWS output settings are reduced below about -20 db or so. I never was able to completely overcome the DRAWS HF audio drive level issues on the 7000. As Dave pointed out, fldigi can be forced to work with an ugly signal due to the inability to reduce ALC with the DRAWS board in its “clean” audio output range. And like Dave’s experience, the latest make of wsjt-x generates too low output so transmit does nothing. JS8CALL is a complete non-issue for me, I have no need for it and I have not played with winlink/paclink etc.

 

Just before I gave up, I tried using a multiturn pot as a simple attenuator and was “sort of” successful transmitting a clean signal with fldigi but never got around to making up a cable that had the right voltage divider built into it. That would not have solved the wsjt-x problem anyway.

 

Since the FM side works well, the 7000/DRAWS combo has become my 24/7 APRS transceiver – provides a “blackhole” fill-in xastir node service here in north central MD running xastir.  The FT-817/DRAWS combo is part of my “go kit”.

 

I believe Basil did experiment with his friends IC-7000, but if I recall correctly, only determined that the FM output could be made to work, but I can’t remember if he actually took a crack at the fldigi/wsjt-x over HF problem and was able to duplicate it. That was about the time I forced myself to stop fooling around with the DRAWS board because it was making me increasingly obsessive (like not getting real work done).

 

It would be great if these problems could be solved!

Re: Nixtracker

Basil Gunn
 

David,

I'm still testing but this is what I had to do get things working.

The tracker_install.sh script disables pluweb.service and starts
tracker.service so that is why your previous web connection stopped
working. That is by design.

You should be able to connect to the tracker server in a
browser with: <ip_address>:8081 where ip_address can be localhost if you
are running on the RPi.

To make this work:
# I believe only uid-number module is not installed but checking the
# other required modules doesn't hurt.

sudo npm -g install ctype iniparser websocket connect serve-static finalhandler uid-number

As root edit /etc/tracker/aprs_tracker.ini
In the [station] section mycall = <your_call_sign>
In the [gps] section comment out with a '#' type=serial
In the [gps] section UNcomment (remove '#') type=gpsd

I've made these changes to the install script so you won't have to do
this manually next time & added a tracker-status script to verify a
couple of things.

To get the new scripts:
cd
cd n7nix
git pull
cd config
./bin_refresh.sh

Also when you get the web page to render if the satellite count is zero
then you may have to pull the latest track source to get a small fix I
put in a while back & forgot to check-in. Check the 3rd panel for
'Locked: 0 sats'. I'll walk you through that later if that turns out to
be the case.

Ahh! I see now how the lvd renders the Ctrl tab obsolete. I didn’t

since it appeared in the NWDR change log. My son bought me the its-12

The its-12 is nice gift!

The history of my mobile APRS device is like this. I was going to an
APRS event & installed nixtracker on the UDR cpu card (not an Rpi) about
7 or 8 years ago and powered it from the cigarette lighter in the
truck. This was supposed to be a temporary setup that I eventually ran
for about 8 years. Note that the cpu card didn't have any power
protection & was powered off/on with the ignition key. That setup worked
flawlessly for about 8 years ie. same mSD card for that time was never
corrupted.

I did not want to run the same experiment with the RPi and now have the
its-12 powered from the truck battery set for 2 minutes. This allows me
to easily detect a voltage change using a DRAWS hat & beacon one last
time when I leave my truck then do a polite shutdown. I've been running
this setup for about 3 months.

Thanks for all your help. As always, no rush. I really wanted to try
plu and nixtracker with a fresh image a third time but that won’t
happen until tomorrow. Claws mail and the wl2k commands work.
I will do some testing over the next couple of days.

Re: DRAWS hat + PiJuice

Michael WA7SKG <wa7skg@...>
 

Not the PiJuice specifically, but I am using the MoPi 2 (https://pi.gate.ac.uk/pages/mopi.html). This does not include a built-in battery like the PiJuice, but has two inputs that accept 6.5-24VDC, a charger input and a management system. It gives you a push button to start/stop the RPi, monitors voltage and will initiate automatic shutdown for low voltage, on-board LEDs as well as on-screen notifications. Each input can configure for different battery chemistries. It also has a relay connection if you need to switch higher current sources.

In my configuration, I am not using a DRAWS hat, but a TNC-X. I think the DRAWS configuration would be similar. The whole package is mounted on the back of a SmartiPi Touch case. It seems to work quite well. I am mounting it in my vehicle connected to the vehicle 12V supply.

Has anybody successfully incorporated a RPi UPS board like the PiJuice (https://uk.pi-supply.com/products/pijuice-standard) to prevent corruption based on power loss, especially while operating mobile? I've got automatic backups to a USB thumb drive set up with RSnapshot now, but it'd be nice to have the PiJuice there to automatically shut down gracefully the RPi when power is disconnected.
It looks like it interfaces using spring pins on the 40 pin connector, and everything is pass-through except power and I2C: https://github.com/PiSupply/PiJuice
Does that conflict with anything that the DRAWS hat needs? My only other concern would be being able to power/charge the PiJuice from the 12v connection on the DRAWS.
