If you are looking to do packet, many major brand VHF/UHF radios work with the "Packet Din-6 Connector" on the radio.  The Yaesu FT-8x7 family is pretty much plug and play with the level setting script(s).

APRS digipeater doing fine with compass beta-5 version

f6bvp
 

Hi,
I downloaded last available compass beta version today and installed it (beta 5).
Just plugged DRAWS hat on RPi 3B+, connected Din6 cable into left din6 plug and YAESU FT-7900 and set APRS frequency.
Starting direwolf -t 0 allowed immediate display of APRS trafic.
After editing direwolf.conf for BEACON to advertize my location and direwolf started digipeating APRS packets.

Some remarks about CARD name and din6 identification labelling:

aplay -l displays harware plugHW: CARD=udrc, DEV=0

Same for direwolf and n7nix/deviation/measure_deviate.sh in the menu and at various places
instead of DRAWS.

measure_deviate uses by default LEFT din6 (audio channel 0) that he advertizes as connector hd15 and PTT gpio 12
Same with option measure_deviate -c hd15 
Starting measure_deviate -c din6 
activates RIGHT din6 plug  (audio channel 1) using PTT gpio 23

Using HD15 may confuse new DRAWS customers for there is no such plug.

Re: (longer) DRAWS power cable? #draws #power

I do not recommend large gauge pigtails.   You don’t want the connectors on the board to be the point of failure.  What we need is a case design that has a securely mounted powerpole or barrel connector.  Then the pigtail won’t matter.

Internet in the field for your DRAWS™ System #mifi #draws #internet

 

I gave a talk about using the amateur radio IP network and a VPN at DCC this year.  See:
https://www.youtube.com/watch?v=OxsmGaFZ2MM&t=5s

With or without the VPN, I like to operate sometimes away from the WiFi or a wired Internet connection.

I often use this little router https://www.gl-inet.com/products/gl-mifi/ with Google Fi service (US ATT model) -- I just saw they have a 25% off holiday special. (This model should also work with T-Mobile and ATT networks with the proper SIM and plan).

If you want to check out Google Fi (who will provide free SIMs to customers for this type of device, sharing the data plan with the account) -- use https://g.co/fi/r/C622J1 and get $20 credit after 30 days.   (I do get a referral credit, if you use the link or they are offering an equivalent 30 day free trial)                                                                                            
Neither I nor NW Digital Radio are affiliated with GL-INET or Google Fi.  I am just a satisfied customer of both of these products, and passing along the information.

Re: (longer) DRAWS power cable? #draws #power

Gayland Gump
 

John,

Thanks for the input.  I am pretty much a rank amateur on the hardware side of things.  I've already managed loose an inch or more off the pigtails trying to put some Anderson Power Poles on them.  Hadn't occurred to me to simply solder longer wires to the pigtails.  I assume that I could go to a larger gauge of wire which would allow me to have a somewhat more robust termination to the connectors I want to try.  That 28 gauge wire in the pigtails is awfully fragile to a fumble thumbs like me.

If you have a part number for the pig tails and a source I'd appreciate hearing more from you.

If that's not how it works, then how does it work?
That’s exactly how it works. The TLV320AIC3204 has three inputs that can be connected to the ADC. Each input also has an inline resistor that you can select from the mixer. We suggest that you use 10k, because that’s been shown to work in all the situations we’ve tried, but if you need to do some advanced configuration you can use the 20k and 40k values. Please also note that it is a valid configuration for the codec to hook both input 1 and 2 to the ADC at the same time. The signals will merely get mixed. So, if that’s not something you desire, remember to turn off 1 when 2 is in use and vice-versa.

Also read the entire mixer description. There are indeed switches for things like “IN1L to Right Mixer” where you can cross things up.

The “ADC Level” analog control determines the input gain for these. Left and right are separately controllable.

I’d love to be able to pare down these options to be more specific to udrc/draws, but the alsa code doesn’t really allow you to do that very easily.

On the output side, it’s quite a bit simpler. There’s one right and one left output off of the DAC. They are hooked to one of two amplifiers, LO and HP. LO is line out, and HP is headphones. UDRC/Draws only brings out the LO amplifier to pins. There’s an “LO DAC” control that should always be on unless you never intend on transmitting. This hooks the output of the DAC to the LO amplifier. There are then two output controls, one for each of the left and right pin. These are brought out to the output pin on the DIN6.

The trickiness here is that there are two level controls for the output. The first is the PCM control. This controls output from the DAC itself. The thing to note about this control is that it’s a digital control, which means it’s really just multiplying input values to the DAC by a scaling factor. That means that the lower you set it, the less effective bits of the DAC you’re using. This can cause more quantization noise in your output. The other control is the “LO Drive” control. This controls the gain of the LO amplifier. Because of the lack of quantization issues, you would prefer to use this one for the bulk of your setting if possible.

With regards to the “LO Drive” and “PCM” controls, my experience has shown that 0dB on both controls is pretty close to clipping the outputs, so use caution when adjusting them above 0dB.

If you need more output than the defaults can provide, there’s a secret device tree overlay called udrc-boost-output that’s in our repository that you can use to change the power source of the LO amplifier. How to use such is an exercise for the reader since it’s rarely needed.

Re: TODO list? Re: #draws #compass #dstar

Basil Gunn
 

@ Basil – which copy of direwolf.conf does your start up script
modify? I am missing the obvious as usual…
Linux configuration by convention lives in /etc or /usr/local/etc
direwolf config is here: /etc/direwolf.conf

With Beta2-

So wsjt and fldigi were a slam-dunk here, they just worked without
mods (I still need to adjust the screen parameters to get wsjt on the
7 inch touch screen)… I used the audio setup that was in audio setup
routine and did not try to use the original audio setup script.
Just my preference:
I found 7 inch screens, even the superior Sunfounder 1024x600 display
are too small to be usable for most of these applications.
I use the 10 inch Sunfounder 1280x800 display.

This was the first time I was able to reliably get a waterfall on any
program!

Basil’s solution for the activation of direwolf worked (and YACC, but
Xastir was still being goofy). When running direwolf as a system
process, there is not an active monitor terminal as is the case when
run directly from commandline or the GUI menu. In my attempt to get it
to work by playing with the .conf file, I messed up something and lost
the GPS. In process of trying to fix that I lost the PTT. Since Beta4
is available, I am just going to flash another image and start up slow
again.
Look here for my notes on bringing up a working Xastir
Note: The gps notes are NOT for the draws board.

https://github.com/nwdigitalradio/n7nix/tree/master/xastir

You can look at direwolf output this way:

tail -f /var/log/direwolf/direwolf.log

draws_beta5.zip is now available.
