Winlink RMS installation

John Spoonhower
 

I am following the process outlined by N7NIX in order to build a Winlink RMS with a Raspberry Pi 3 and UDRC-II.
I have completed the CORE-INSTALL scripts and everything seems to run just fine after rebooting.
However, if I "manually" stop running services with ax25-stop, and then restart manually with ax25-start, there is an issue with mheardd.
When I execute:
sudo ./ax25-start, I get back the message:
A dependency job for ax25-mheardd.service failed. See 'journalctl -xn' for details.

This can apparently get fixed with a system reboot.
Any ideas what happening here?

John, NX2I

 


Re: 6 pin mini DIN adapter for GM300. Will the radio do 9600?

Richard Hendricks <rickh6155@...>
 

JU551 is for the receive, and does work.  I have the adapter board from Argent and the GM300 receives 9600 baud very well, however, the transmit audio
on the adapter is fed to the MIC AUDIO (pin 2) of the GM300, which will not work.  I've tried injecting into FLAT TX AUDIO (Pin 5) which doesn't work either,
as it distorts the 9600 baud eye pattern.  I've inquired to Argent, and John Cape informed me that I should look at C1 on the board (I requested and got a
schematic from him) as it may be the cause of the distortion, but the eye pattern going into the small amplifier transistor is clean on both sides of the
referenced capacitor.  I just downloaded the schematic for the French version, and see that it does, in fact, directly inject the 9600 baud data signal into
pin 5 without going thru any amplification.  So, I'll do some testing with the Argent Data module and see what I can devise by diverting the 9600-baud
data away from the amplifier transistor and directly into pin 5 of the GM300.

Hi Steve,

Being involved into an EME project with a 10m dish radiotelescope antenna in Paris (France), we are considering using a LimeSDR mini TRX available for 139$ + 10$ shipping.

https://www.crowdsupply.com/lime-micro/limesdr-mini

Device is supported by http://www.sdr-radio.com/Radios/LimeSDR

You may browse the web for "Raspberry & LimeSDR" and will be surprised by the number of projects involved from AMSAT to Ham TV.

I haven't found an SDR that will transmit yet...

That's a good question and even after all these years that's still the
big problem.   While there are some good'ish radios they are expensive
and which they are is not well defined.

It also depends on what you want to do...   APRS, HF, Higher Speed data...

25 years ago we had the Kantronics D4-10 for 9600 baud to 19200 baud.
It used crystals and was about $1000 is 2018 dollars.

Today we have the Kenwood TH-D710 for $600

Others are around $300.   https://groups.io/g/nwaprs/wiki/Radios-for-Packet

Maybe SDR will be the answer.

Re: UDRC-II Suitability

 

We generally are not bringing inventory to Hamfests due to the hassle of setting up to collect sales tax and then remitting it.

If you would like one, it is best to just order it on the website.  http://nwdigitalradio.com/product/udrc/

I have replaced dvrptr boards with UDRC on a couple of repeaters. In my estimation the UDRC works better.

Re: Digi-Pi

Chris - KC9AD
 

Hi Steve,

 

I am a real Digi-Pi noob, but I, and several of my local ham colleagues are using the Digi-Pi for FSQ mode comms. We use the Fldigi software running under Linux on the Pi. FSQ is a very low speed chat mode, keyboard to keyboard, that we use on VHF FM simplex, 145.580 MHz. To address your specific question, I am using a Kenwood TM-V7 dual band mobile radio; it has a mini-DIN-6 “data” connector on the front panel. Elsewhere, we are using a Yaesu FT-8900R; it has a mini-DIN-6 connector on the back panel. So, the UDRC (aka the modem), is connected to the radio data port using a straight-thru cable with a male mini-DIN-6 on each end. You can order that cable as an option with your UDRC-II. Other radios can use different connectors, like maybe a DB-9, so you might need a different cable. The UDRC has two radio port: a mini-DIN-6 connector and a DB-9. You select the one you want in the Fldigi configuration menu. Once the radio is connected, it is controlled by the software. So, you type a line of text and, when you hit enter, the UDRC turns on the PTT and transmits your message via the radio.

 

I realize that there’s a lot more to it, but hopefully this adds to your understanding. 73.

How do you connect it to your radio?

What is he transmitting/receiving?

A lot of the digital mode videos seem to start after the radio is connected and go over the software.  I haven't figured out yet what kind of radio I need or how to hook up after I have it.

Re: UDRC Direwolf Wiki has wrong settings for UDRC2 in dIrewolf.conf

Robert Sears
 

That might work, I recall someone suggesting a database of radios and alsamixer settings before, so we could have a good starting point for most radios.

Oh yeah, sorry group I did not know this was one of those forums that send out an email every time I make a punctuation, or grammar correction from he web interface.


Re: UDRC Direwolf Wiki has wrong settings for UDRC2 in dIrewolf.conf

Gayland Gump
 

Thank you, Robert!  Finally got one of my systems working.  Still having problems getting receive levels to work on the baofeng HT and the BTECH with direwolf.  Both of them were working the last time I checked with fldigi and the current alsamixer settings.  How well is still a question but now that the damned basic direwolf configuration issue has been resolved.   We might be able to create udrc-alsa profiles optimized for each radio type, or am I just blowing smoke out my keester?

This is wrong as the schematic clearly shows the PTT on the 6-Pin DIN is being driven by GPIO 23 and in Xastir to use the DIN-6 you have to set the "Interface" Transmit Port to 2 because that is channel 1 on the UDRC2

The sample Direwolf.conf labels need to be swapped like this
