If we have a case on backorder (ordered mine a couple months ago) will we be receiving the Pi4-compatible cases or the old Pi3 case?

FWIW, at this point I'd rather have the DRAWS board in hand and I can wait on the case if I have to. I won't have my Pi4 until July anyway.

Re: Raspberry Pi 4

 

Hi All,

The new Raspberry Pi 4 has some interesting features and we certainly will be looking at it, however, we at NW Digital Radio do not get any advance engineering information from the Raspberry Pi Foundation, so we must also wait for shipments to have test units.

In the short term, we recommend sticking with the currently supported models of Pis unless you are familiar with building software and self support.

We are also looking at updating the design for the production (non-beta) DRAWS™ aluminum cases to accommodate the 2, 3, and 4 Pi motherboards.

Stay tuned.

I’m in the same boat as August! We deserve to be apprised of the situation considering how this has been handled. I travel a lot and have zero comfort level that I’m ever going to see this case!

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

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.

Question HW and SW

Markus
 

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.

I think Data Mode: USB uses the microphone & speaker outputs so I
wouldn't use that.

Have you tried Data Mode: None
This prevents wsjtx from changing your radio mode setting.

Use the measure_deviate.sh script to verify you are able to send a tone
out your radio. ie. Use a second radio tuned to the transmit frequency
of the first radio. Get this working first as it is basic functionality
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.

WSJT-X set to "Data Mode: USB" gives me decode and "open mic". I can not

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.

the tuner will tune if the radio is out of range.

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