Re: [New post] DRAWS™ Cases Have Shipped!
The Barrel Connector was incorporated into the latest Boards. There is a PowerPole to 2.1mm DC Coax Cable available from Powerwerx
If you have an earlier board you can terminate the supplied JST XH Pigtail to anything you like, wether it’s coax, PowerPole, or whatever works for your application. Of course most of you have already done this. These pigtails are available from Pololu and others if you need another one. MAKE SURE TO CHECK POLARITY! as they are not all the same.

May I ask about the power connections. On the original case you said you were including a barrel connector for power. I still the case with the newer cases?

Great News. Will the the "early adopter" case work with the PI 4? The website photos are not displaying with an image of the case. Looking forward to receiving it. Ordered it back when I running it on Pi 3. Thank you. JJ1PJI Kevin

new membership and NW DRAWS with Codan NGT and/or 9360
Tino HB9DUW
Hello from Switzerland (HB9DUW, op. Tino) and happy new year! Thank you for letting me in. I became aware of DRAWS HAT only recently and find it a good option for my project : Setting up remote HF ARDOP station on a Raspberry and Codan NGT SR(x) and/or 9360. Does someone know the NW DRAWS pinout for these particular TXs? I'd like also please to get some of your experiences in choosing the best "clothing" for Pi3/4, considering this remote setup with 12v solar pannels, regulator (about 19v to 12v battery) and a fan to extract heat and/or humidity from a "sealed box".---> Waiting for the new NW aluminium case HF destroyed one of my first solar regulator but a 30ish USD Amazon unit seems to be less sensible. Where shall I place ferrites (or other protections) ? Any hints welcome. 73 frm HB9DUW

Re: #support Low transmit audio

Hey Basil,
Thanks for replying. That is the 6-pin MiniDIN adapter that I have.. I even tried my spare with no success. It's had this issue from the start and I did get frustrated with it and gave up. Just decided to pick it back up and give it another shot. I've only ever had it out in the open without a fan. It does have the heat sinks on it as well. Luckily I've been on the list for a case which as a built in fan so hopefully that will work after the fact. What would be the process if I do have a defective DRAWS hat? It's had this issue from the start and I did get frustrated with it and gave up. Just decided to pick it back up and give it another shot. Kyle

With a little digging you can find the unique identifier for the plugged in CT-62 cable and create a udev description to give it a name that remains consistent between plug-in instances. It makes link at /dev/ThumbDV regardless of which ttyUSB# the device is plugged into.

An example for the ThumbDV™ is found at https://github.com/nwdigitalradio/ambeserver-install/blob/master/etc/udev/rules.d/99-thumbdv.rules It makes link at /dev/ThumbDV regardless of which ttyUSB# the device is plugged into. Also doing a ls /dev/serial/by-id will provide a direct path to the plugged in USB serial device.

Re: NWDR18 image release announcement
Re-stating your problem to see if I have it right:
toggle quoted messageShow quoted text
CAT control is not working between an RPi 4 and and a Yaesu FT-100D which is a multiband HF/VHF/UHF radio. Connection is through a Yaesu CT-62 cable which is an 8 pin mDin to USB serial device connection. This has nothing to do with the DRAWS hat! The most common problem is finding the correct Linux serial device name for FLdigi/FLrig. # With the CT-62 disconnected from the RPi find all current USB serial device names: ls /dev/ttyU* ls: cannot access '/dev/ttyU*': No such file or directory # In my case their are NO USB serial devices plugged into the RPi. # Now plug your CT-62 cable into your RPi and execute 'ls' to find the # name of the serial device. ls /dev/ttyU* /dev/ttyUSB0 # In this case the USB serial device name is /dev/ttyUSB0 # This is the device name to use in your FLdigi/FLrig configuration for # CAT control. Note if you unplug/plug your CT-62 cable in your RPi while it is running the device name will change. Eric Williams <kf4yep@gmail.com> writes:

Thanks Basil for the rapid response,
That's good to know. So, how do I get the frequencies to show up in the display and/or flrig? The cat cable is CT-62 with USB end. No serial-to-usb converters in the middle.

Re: NWDR18 image release announcement
Eric,
Placing A Hold On Kernel UpgradeYou do NOT need to place a hold on kernel upgrade. That procedure was to fix a problem that affected the DRAWS overlay last summer. I will take this reference out of the 'Getting Started Guide' later on today because that section was "For reference only, the current Linux kernel is safe to use with DRAWS" The drivers in the current kernel, 5.4.79-v7l+ #1373, works fine with DRAWS. kf4yep@gmail.com writes: Hi team, --------------------------------

Hi team,
I've been having issues with the Draws hat and it is installed on a Pi4. I first tried getting it to work on KM4ACKs Build-a-Pi (Ham experimentation right?). Then I formatted my sd card and followed the getting started guide https://nw-digital-radio.groups.io/g/udrc/wiki/8921 for image nwdr18.img.xz 2020-Dec-05 08:36:33 1.8G and got as far as the fldigi configuration. ax.25/direwolf appeared to work and sent/received appropriately. fldigi keys the radio (yaesu FT-100d attached currently to 1 watt to dummy load) but it appears my cat cable is not reading or setting the radio frequency so I also tried fiddling with flrig to no avail. I stopped here. Reading further: Placing A Hold On Kernel Upgrade
and n7nix's verify_config guide 'sensors' fails to show ads1015-i2c-1-48 so I try
I formatted (again) and haven't connected to network or configured anything. First check of uname -r gives me 5.4.79-v7l+ Help, please and thank you! Eric Williams de KF4YEP

Re: #support Low transmit audio

Use deviation guide here:
toggle quoted messageShow quoted text
https://github.com/nwdigitalradio/n7nix/tree/master/deviation Running measure_deviate.sh will allow you to output a tone so that you can use alsamixer to change the 'Lo Drive' & 'PCM' alsa controls. I used the Argent Data 6-pin MiniDIN adapter for the Moto CDM 1250 https://www.argentdata.com/catalog/product_info.php?products_id=169 You have to be careful how you plug that into CDM 1250 It looks like you are using the right hand mDin 6 connector. Channel 0 is the left hand mDin6 connector which is the default connector for using scripts to set up packet. If you can't get enough volume using the measure_deviate.sh script you may have a defective DRAWS hat. The soft temperature limit bit is set in the get_throttled register. The current temperature, 59C, is fine but at some time your RPi over heated. kylemcdonald87@gmail.com writes:

First off thanks for creating such a versatile board!
I've ran through the setup a few times and I'm still having the same low transmit audio problem. I've tried it with 2 radios (FTM-400 & Motorola CDM1250). I have to have my HT turned up all the way and I can still barely hear the data bursts. I've tried adjusting through Manager as well as alsa from ssh and I'm not able to get much change. Here is the output from my showudrc.sh: https://pastebin.com/raw/krbtCAm8
