Could someone email me and see what i'm doing wrong?  I can't seem to get the hotspot to work on my pi, with or without the draws hat.  I used the instructions that julian linked to.

I'd be happy to help you troubleshoot Douglas. For this sort of thing whether you have the DRAWs hat or not won't matter, this is simply a rpi/linux networking configuration.

Do you have access to your rpi on a monitor and are you able to troubleshoot the networking configuration?

Re: Using a PiDrive with Draws HatUsing a PiDrive with Draws Hat

I'm not an expert but I believe it will work on the PiDrive as long as you use the PiDrive power instead of the 12 volt supply. My new Pi3B+ should be in by this weekend. I will try my draws on it and see if I still has troubles. As far as my PiDrve it is working just fine. So the draws hat is what may have been what was damaged. If you can wait awhile I will update with further details.

ThumbDV - AMBEServer #thumbdv

andyw999@...
 

Hi

I have a ThumbDV running at 460K.

It runs fine with AMBEServer in half duplex mode sending either SPEECH packet or CHANNEL packet.

I am sending companded 160 byte audio packets and get back the AMBE packet OK and this runs at 50 packets per second as expected.

 

If I then loop the AMBE packets back I only see ~34 packets per second being looped back and if I stop sending packets it keeps going for quite a while as they have been buffered.

 

It also will do an internal hard reset when it gets really upset -

 

Received Serial data packet with type 0 and length 1:

0000:  61 00 01 00 39

 

I know the chip is supposed to do full duplex but has anybody tried it successfully?

As at this point I do not know if it is a limitation of the AMBE chip in packet mode or something stupid I am doing!

Thanks

Andy.

John,

I have a Kenwood TM-D710G and several ICOM HF rigs.  None have a 6 pin jack.  So you recommend that I fabricate a plug to match the pin config with of the supplied 6 pin cables.
Did you supply a pin configuration for your supplied cables?  Also, the ICOM seems to have a common 8 pin ACC connector but does not have the PTT, DISC or AFOUT, AFIN, and SQL (plus GND) you list.  However, the mic connector has all but a DISC.  Do you intend to use the mic connector and what is DISC?

Mr. Hirsch,
 
Please check out Ham Made Parts at hammadeparts.com.  Les, WY0GTR, has many of the cables already.  He adds more as they are requested.

Re: DRAWS

 

Hi Fred,

The mini-din 6 connector is common interface across vendors who provide a packet radio interface.  Here is a diagram of the pinout from http://www.wa8lmf.net/6-Pin-MiniDin-Data-Connector/index.htm

image.png

DISC is "DATA out 9600" this is audio from the discriminator (in an FM radio).  It is what some call "Flat Audio" with no pre-emphasis filtering.
AF is "Data Out 1200" this is shaped audio which has been filtered and would be typical of what one would hear on a speaker or headphones.

AF is fine for analog and many of the HF data modes and traditional AFSK packet.  DISC is used in more sophisticated modulation schemes such as GMSK.  If your radio doesn't have a one-to-one matching socket, then a cable must be made to go to equivalent points on your radio.  One would look at available connection points on their radio, usually a socket of some sort, and make a cable that matches them up.  There are diagrams for various radios on the Internet and there are people who make them, like https://hammadeparts.com who will fabricate them.

You will note on DRAWS™ Manager (http://localhost:8080 on your DRAWS™) a tool to help select AF/DISC connectivity for a radio.

BTW, the discussion group https://nw-digital-radio.groups.io/g/udrc/ is the correct venue for DRAWS™ and UDRC topics.

The TM-D710G does have a 6-pin DIN jack compatible with DRAWS. It's on

Thank you found it and it is compatible.  Which app would you use with the TM-D710G running APRS with a weather station?

Re: DRAWS

john.chabalko@...
 

What do you want to do with the D710G? If you want to run APRS you don't need to do anything, just plug your weather station into the radio, configure APRS in the D710 menus and you're rolling, no PI required. 

If you want to run echolink, or another digital mode with the radio, then setting it up with DRAWs is a good option. You'll need the right wire from the kenwood round serial connector -> DB9 -> USB, or one that goes direct from the round connector to USB.

You'd use the RPi to control the radio via USB and connect the "DATA" port from the kenwood to the DRAWs. Then i think any of the digital mode apps would be an option providing there are other users on 2m/440.

If i'm misunderstanding what you're trying to do let me know.

Re: RPi / DRAWs Connectivity in the Field and at Home #draws #field #networking #avahi

The instructions Julian provided were excellent. Easy to follow and worked the first time. But if I read correctly, the original poster is needing a way to connect wirelessly to the home network, and then when in the field, have the Pi realize that there is no home network and start the wireless hotspot. That is exactly what I need also. I really don't want yet another box (network extender), power cable, and LAN cable taking up space.  That is the whole reason I wanted the DRAWS in the first place, to eliminate clutter. Why did I go ahead and try Julian's recommendation? Because even though it wasn't what I needed, I needed to make sure that I was actually capable of following instructions! I have tried 3 different tutorials and none of them have worked.  After 3 failed attempts, I was truly beginning to think it was operator error.

Re: fldigi with DRAWS #draws #fldigi

My guess is you’ve got the PTT configuration incorrect. Some of the apps I checked had it defaulted to VOX mode, once I changed to CAT it worked fine (you could also configure your radio to accept VOX too if that’s an option)

it sounds like otherwise everything’s working. I bet it’s that or something related.

EDIT: do you just have audio? Or do you have a rig control serial/usb cable connected? If you only have audio you’ll have to see if VOX is an option

Re: DRAWS

Fred Hirsch <Hirschfh@...>
 

John,

I primarily want to monitor the radio and its APRS function.  I would like to access the APRS Log and be able to change APRS parameter to include
the embedded greeting message.  I do not want it to anything more on 2 2 meters.  Now HF may be something else.  For example, I would like to do RTTY with it.

Re: DRAWS

john.chabalko@...
 

You'll probably want to hear from someone who's doing this but i think if you want to do that you'll want to use Xastir - which is part of the DRAWs image i think. but to monitor the APRS packets i think you'll essentially be using the DRAWs to do APRS and effectively bypassing the TNC on your D710.

If that's actually the case you could probably use any 2m radio with sufficient power output. Curious to see how you get it sorted out.

Re: Using a PiDrive with Draws HatUsing a PiDrive with Draws Hat

okiejim
 

Howdy all,
Here's an update. I received my pi3B+ and hooked up my draw hat. I did not use the 12 volt power I used the Pi power instead. I have a working Xastir station now. So not sure if I really did any damage when trying on my pidrive. I just don't know what the smoke was from and I am gun shy now of trying the 12 volt input again. I really want to but I really wanted to play first. I'm using a Yeasu ft-847 as I want to try the ft8 digital format. I left the new pi and draws hat powered up overnight with the radio turned off just in case. All seems well today. More to come.

Re: RPi / DRAWs Connectivity in the Field and at Home #draws #field #networking #avahi

john.chabalko@...
 

I've got this working, it does exactly what i was looking for. It will join my home Wifi when i'm at home, and if my home wifi is unavailable (eg: i'm out somewhere) it'll configure a static IP address on the RPi wlan0 interface, fire up a hotspot and i can connect to that from my computer/tablet/phone and use the Rpi as a standalone device.

Here's the link i ended up following.

It's a little bit fiddly in that it seems to take a while to bring up the access point after reboot. I was debugging the autohotspot script and all i can see is that it fails while provisioning the interface due to device busy, but then after ~2 minutes it works (i run the pi headless so am looking at the logs after the fact.

SSid's in range:  ++ iw dev wlan0 scan ap-force ++ egrep '^BSS|SSID:' command failed: Device or resource busy (-16)

The next thing i'm going to mess around with is if i can get it to join the "personal hotspot" from my phone/tablet and let me connect to it and have internet access from the RPi while i'm not at home.
