It may be worth noting that "You MUST make sure to upgrade your Raspbian operating system install to the latest version so that the firmware can support the new chips! Old SD cards from previous releases will not work without a upgrade!", per the Adafruit web site announcement.

Hopefully Anna's kernal update for the DRAWS chip drivers makes it into the Raspbian image soon.

Re: Question HW and SW

okiejim
 

This sounds like my weather voice system. The second radio is a ctually a repeater and no need for the second rpi or udrc. It converted the text from a weather station to wav file and sent them over the radio to the repeater. I have just now started re-coding it for the DrawsHat in Python. It will take some time as I am not dedicated to it just wanted to play around, and get it running again. I originally wrote it in visual basic on windows. Keep us informed. When I get going on it I will post something here. I have a dtmf decoder I used but hope to incorporate direwolf to reduce the hardware requirments. The DTMF was what triggered the weather report to go out to the repeater.

Hello community,

I have a question whether such a constellation would work?

Linux -- RPI -- UDRC HAT -- (Radio equipment)

<------->

(Radio equipment) -- UDRC HAT -- RPI -- Linux

How the radio equipment would wire now with the HAT UDRC?
I would like to make a BASH script from the console an send some text.
As software MINIMODEM is supposed to run the tool. http://www.whence.com/minimodem/


Software steps in the Script:

- Text convert to WAV (audio file)
- wait
- push the PTT
- wait
- play Audio
...

Thanks for help.

Bye Markus

I have the data cable plugged in and I've used data/pkt successfully before.  This is why this is so frustrating... it used to work and now nothing works.

I'll have to see what I can rig up to run with the measure_deviate script and report back.

This prevents wsjtx from changing your radio mode setting.

Use the measure_deviate.sh script to verify you are able to send a tone

you can build on.

Re: DRAWS Video #4

Steve McGrane <temporarilyoffline@...>
 

All very good answers so far.  But since you specifically asked for my opinion, I guess I should oblige...

HAM is "A hobby of a thousand hobbies", so even though your radio has a built in sound card, and wasn't really built for mobile operation... DRAWS might be a "cheap" GPS option.  With the capabilities this Hat offers, the community might offer better features in the future that you can't live without.

For me, I'm looking to build out a mobile station with "DC to Daylight" and all the apps that go with it.  Eventually I'd like to do APRS, FLDigi for transmitting both data and files, chase satellites and even some CW in the park.

If you find value in using the Pi platform for Rig Control and WSJT-X digital modes only, then you probably won't need the DRAWS hat.

I can't really even begin to list off all the things that could be explored through this platform.  Would be great if there was an open Wiki were we could contribute some documentation and experiences.  How long would the list be?

I already own a signalink and I got the hat to use in place of the signalink... but in my defense, none of the radios I own have a built in soundcard.

>Debug?" thread?

It was running fine after I ran my ft-891 script a few weeks ago, and it got better after I ran it again... but doesn't work 100%.

From the audio debug thread, I thought I had it working, but I didn't... I can either decode or I can transmit (by switching modes in WSJT-X), but since I can't do "both", I can't have a successful QSO.

The measure_deviate script runs, but other than putting info on the screen, doesn't actually do anything.

alsa_show results are above.

This is a continuation of the audio debug thread with some new information and a picture of the waterfall.  Since I closed out that thread early, I wanted to start a new thread.

DATA MODE: OTHERS
PSK TONE: 1000Hz
OTHER DISP: 0Hz
OTHER SHIFT: 0Hz
PSK/OTHERS: Don't appear to have this one.

I would imagine that you guys don't have every radio, but I was hoping to be of some help with audio settings and providing a script that works (used to anyway) for future releases.  I sent in the details from Yaesu and my interpretation of translating them for the setalsa-X script after the contest a couple of months ago.

For grins I did a factory reset of the radio, nothing changed.  I can reload the DRAWS SD card, but I'm not sure that would really have any effect either.

I'm at a loss of what to even attempt to change/fix next.

Symptoms:

WSJT-X set to "Data Mode: USB" gives me decode and "open mic".  I can not transmit successfully in this setting.  PTT opens, but no carrier/signal is sent.  I can tell this by my external signal meter not moving, the SWR meter on the radio doesn't move and the tuner doesn't budge.

You can see the difference in these two modes in the waterfall pic I sent before.

Not for any particular reason, but these are just my observations.

Could you be more specific about what your are expecting.
