Hi all,

The DRAWS board arrived yesterday evening, and today I picked up a new
Raspberry Pi 3 to connect it… so far things seem to be working but I'm
yet to hook up a radio.

Now, with the predecessor board (which has seen some use as a packet
radio station), I had to make a small modification to get audio on the
FT-897/857…

https://stuartl.longlandclan.id.au/blog/2016/11/20/getting-the-udrc-ii-to-play-nice-with-the-yaesu-ft-897d/

I've also used this same board with an Yaesu FTM-350AR and a Icom 706 MkIIG.

For the DRAWS, I intend to use it on my bicycle, which runs a FT-857D.
The plan is I'll set up two transceivers: a Wouxun KG-UVD1P I have
laying around set on 145.175MHz for APRS; and use the other port going
to the data jack on the FT-857D. I'll use the DRAWS auxiliary port to
control the CAT interface.

With the Pi acting as a WiFi access point, I should be able to use a
Mumble VoIP server to allow my mobile phone to connect and act as a
"cross-band repeater".

Thus when operating a check-point (like I was for the Yarraman to
Wulkuraka bike ride¹ last year), instead of being tethered to the
bicycle, I can plug my headset into my phone instead and still have
80m-70cm all-mode capability.

For this to work, I still want to be able to use my radio normally, so
basically be able to plug the headset into the microphone/speaker jacks
on the set, and use it like I do now -- as Queensland road rules
preclude me from using a mobile phone whilst in transit *for any reason*
(unless I want an AU$1000 fine for my troubles).

Do I need a pull-up on the SQL lines like I did for the UDRC-II in order
to have normal audio on the FT-857D/897D?

Well, got it down, and now I see why it's 2.6GB in size… it's a
full-blown desktop image. I usually like to start with a minimal image
and add what I need rather than starting with a big image and having to
slim it down.

I might have a look at this and see if a smaller image can't be
produced… I think a more "compact" image would be a little easier to handle.

Not difficult to have a small image which just downloads "the
essentials", then asks some further questions to install the rest
(including a full-blown GUI if needed).

I might look into this as I'd like something built on the Buster release
of Debian rather than Debian Stretch as some of the software I'm writing
will require it (or rather, require Python 3.6+; Buster ships with 3.7,
Stretch with 3.5).

Is there a mirror of the Compass Linux for the new DRAWS board? At the moment I'm downloading the "draws_beta13.zip" image off of nwdig.net.

Re: #Draws used with #WinLink with #BTech 6X2 #DMR radio..... #winlink #btech #dmr #draws

 

At first blush, what you are describing isn't practical.

DMR uses the AMBE vocoder to pass voice communications and it will not reproduce tones for the modems typically used for Winlink communications.  Winlink typically uses AX.25 packet or Ardop (and possibly other) analog modems.

DRAWS™ supports AX.25 and Ardop, so in analog mode, you may be able to do Winlink communications with that radio.

Also amateur radio DMR does not provide private communications.  It will do radio-to-radio routing (not connections), but it can be monitored by other stations using promiscuous mode.

Maybe folks will have some ideas for you.

To add to the collective knowledge, I had to run rpi-update to get the latest firmware (working on 4.19.66-v7l+ #1253 SMP Thu Aug 15 12:02:08 BST 2019 armv7l).

I'm running otherwise stock Buster and installing only those apps that I need at present which for the time being is Direwolf for an APRS Digipeater/Igate.

Currently using RPI4, and yes, it does need a fan! I'm going to move the DRAWS hat to an idle Pi3.

Just wondering, I know people have gotten wsjt to work with cat control or usb control, but has anyone gotten a work around to use the gpio pins for the ptt?

the main reason I ask is that when i switch radios I don't want to try to mess with cat or usb control, and some of my rigs have neither. it would be nice to be able to switch between any radio w/o extra control cables.

I haven't played around with hamlib enough to know all its features yet, but has anyone added gpio support to it?

paclink-unix that you are using ... unless he is using paclink-unix.
I have only tested p2p with Airmail & Winlink Express.

With this information we'll run some more tests.

I don't know. Expand the columns so I can see all the information.

paclink-unix is SMTP compliant and uses postfix to set the required
email headers. The email that you compose with paclink-unix will be
accepted by any other SMTP compliant email system. Try CC'ing your gmail
account when sending messages either with wl2ktelnet or wl2kax25. For
p2p it only makes sense to have a single 'To:' destination address.

This is getting very very close. It's going to be very helpful for

(nearby winlink machine), telnet (CMS) or ax.25 (winlink RMS

To send a message via p2p use wl2kax25 & drop the SSID from the call sign,
that's all there is to it. ie. wl2kax25 -c n7nix

You are using an unqualified email address. If you did this using mutt

Send me the file you are about to send from /usr/local/var/wl2k/outbox.
Looking at that file I can tell you whether it has a chance of being
sent properly.

Exercise for you:
Compose a single message to k7rmz@... and copy it to a temporary directory.

Send it using: wl2ktelnet

Copy message from temporary directory to /usr/local/var/wl2k/outbox
Send it using: wl2kax25 -c k7rmz-10

Copy message from tmp directory to /usr/local/var/wl2k/outbox
Make sure k7kmz is set to receive via p2p.
Send it using wl2kax25 -c k7kmz

Cut & paste the console output from those 3 transactions in a regular
email to me.
