Re: DRAWS Hat GPIO Pins

Hi Jeff,

Additionally I want to point you to WiringPi PIN based GPIO access library written in C.
We are using it to access via GPIO a 24 bits multiplexer HAT in a project for controlling our radio telescope at La Villette in Paris.

Re: DRAWS™ and YAESU FTM-100 for analog and digital modes

The best thing to do to set transmit levels is to use John's DRAWS
Manager web config.
https://github.com/nwdigitalradio/n7nix/blob/master/docs/DRAWS_ALSA.md

Also know that script setalsa-default.sh changed at some time as the
initial values used were way too hot.

Hi John,

Here my FTM-100DE is quite new and I just ran setalsa-default that made audio receive and transmit levels adequate.
For the moment I did not try any deviation measurements.

FTM-100DE is an interesting mobile VHF/UHF FM rig that I am using at

As a transition device it has both "analog" and new digital C4FM modes.
Data plug is a 10 pin mini DIN while UDRC II and DRAWS have mini DIN 6

Hi Jeff,

Just try:

Re: Brief Introduction and Some Generic Information #ft817 #din6 #audio

 

There are two ways that Raspbian (the operating system for the Pi) can boot up, one is to a command line with a login prompt, the other is with a GUI (either already logged in or with a login screen). 

Current beta images default to GUI, already logged in.

If you look at the solder pads under the white power connector, you'll see that one is square (the one nearest the GPS). Square = positive.

Dave N20A,

I checked-in a fix to the problem that you reported with beacmin.sh.
Fix GPS to APRS position format: Degrees Minutes.m
https://github.com/nwdigitalradio/n7nix/commit/5821f4ff36b3ca976439c9325f484664476e839a

To get the new script:
I you modified the beacmin.sh script in n7nix/debug then you need to remove it.

cd
cd n7nix/debug
rm beacmin.sh

# To get new script
git pull

When you first run beacmin.sh in may take some time to install the bc program, an
arbitrary precision command line calculator. It will run much more
quickly the next times.

When you get a chance please run beacmin.sh and let me know if it meets your
expectations. You should edit the script to set the SSID to what ever
you want. You should also set the beacon_msg string to use a different icon

Thanks,
/Basil

Re: +12V polarity? #12vsupply

 

Thank you sir, that clears up everything. And copy on the 2A fuse. I have my pigtail sorted now but thanks for the kind offer to send another. I WILL buy one of those nice looking cases when they come online!

David KE7RGP


Re: +12V polarity? #12vsupply

 

Red Lead Plus is on the right on all DRAWS Boards. They were opposite on some prototypes that were never shipped. Hence the documentation.

Some pigtails arrived reversed so we had to swap them. This has been a problem, so we have a new dedicated supplier that builds to our spec,

If your cable is BW let us know and we will ship a replacement.

There is a reverse protection diode but if you haven’t fused the link (2A recommended) the diode will short out.
