Headphone/Microphone break-out?

Stuart Longland VK4MSL
 

Hi all,

Silly thought just occurred to me… one sore point with the Raspberry Pi
is that the device provides no audio I/O apart from the PWM audio output.

Now, the UDRC/DRAWS is a big improvement on that, with a decent audio
CODEC chip capable of 192kHz audio. There's 3 line-in channels, a
MICBIAS output, a line-out and a headphone output, all available on the
audio CODEC chip. The mixer is able to do all kinds of routing voodoo.

With such a set-up, whilst of course you won't drive a headset and two
radios off the two ADC and two DAC channels, you could conceivably drive
one radio and one headset with the right routing settings, or use the
headphone output as a monitor.

In applications where you just want something to connect a headset to
your radio for SSB/FM voice, that can be facilitated through the mixer
alone (no latency as it's purely analogue): e.g. if the microphone
hooked to IN3[L+R], you could route IN3L→LOL and IN1L→HPL; or IN3R→LOR
and IN1R→HPR.

You'd then just need a switch to connect your headset either to HPL or
HPR (or both if you want to use the UDRC/DRAWS as a sound card for
music, etc).

Anyway, it was a thought that occurred to me. Maybe in a future design,
a small pin header could expose those pins for those who choose to use them.

Regards,

Re: Fans, Pi4, and the DRAWS case

Chris Metcalf
 

FWIW, the “Pi-Fan” brand fan that came with my case is _extremely_ quiet and can barely be heard even from a foot or two away.

A big passive heat sink could possibly help, but the “hat” standard makes that difficult since the hat sits right on top of the Pi and doesn’t leave much room for a heat sink. Perhaps a later generation case could include a riser or some sort of heat pipe system to dissipate heat outside the case.

Key learning though is that it looks like the Pi4 is impractical without some sort of cooling for the CPU. I’ve still got my 3B+ and may reconsider it if the power and cooling requirements are too high, but right now I’m _loving_ the extra memory and CPU.

Orienting heat sink fins vertical and given that warm air flows up, makes the best use of passive cooling. Can you tell that I am an engineer? Apologies. Probably good that there be a little air space around below and above the heatsink. 

On the other hand, the specs for fans include the dB noise level and a very quiet low speed fan can greatly improve heat exchange in any orientation. Just read the specs and investigate.

JT Croteau <jt.tobit@...>
 

I am hoping the Pi 4 draws less than 20W.  I run completely on solar power and looking for a desktop replacement with DRAWS.  Fan noise can be mitigated.   I have a 2n1 laptop/tablet that draws about 25W but I'd much rather have the DRAWS and some other apps in one device.

The extra power (and the 2 GB or 4 GB of RAM) of the RPi4 is nice, and
I plan to have at least a couple, probably as standalone workstations,
but on the DRAWS, I haven't seen / heard / read anything that
indicates that the additional power of the RPi4 would be of any
benefit to a DRAWS unit above and beyond what the RPi3 does. Thus, the
RPi3 which doesn't need a fan, is preferable to the RPi4, which does
seem to need a fan, for use on DRAWS.

I plan to have at least a couple, probably as standalone workstations,
but on the DRAWS, I haven't seen / heard / read anything that
indicates that the additional power of the RPi4 would be of any
benefit to a DRAWS unit above and beyond what the RPi3 does. Thus, the
RPi3 which doesn't need a fan, is preferable to the RPi4, which does
seem to need a fan, for use on DRAWS.

Thanks,

Steve

Re: FLmsg does not launch on DRAWS

Basil Gunn
 

Library libjpeg9-dev is installed from the HF programs install script.

~/dev/github/n7nix$ find . -iname "*.sh" -print | xargs grep -i "libjpeg"
./hfprogs/hf_install.sh:PKG_REQUIRE_FLDIGI="libfltk1.3-dev libjpeg9-dev libxft-dev libxinerama-dev libxcursor-dev libsndfile1-dev libsamplerate0-dev portaudio19-dev libusb-1.0-0-dev libpulse-dev"

We found the fix. Ironically NWDigital sent out this fix in April, but
never put it on their own image.
Not really ironic. If you search udrc group.io messages 'libjpeg9' is mentioned 9 times
since 12/23/18. Maintaining an image with 25 apps that are changing
regularly is challenging some things fall through the cracks.

I just loaded the latest image for DRAWS and have things working, however when I attempt to launch Flmsg, I get an hour glass that runs for a while and then nothing happens. We all use FLmsg weekly in Whatcom County. It runs just fine on my UDRC image. Has anyone else seen this problem?

Re: FLmsg does not launch on DRAWS

Hi Budd,
I'm assuming you launched flmsg from an icon or menu item. If you want
to look at what's going on start flmsg from a console.

The most common problem with flmsg not starting is that library
libjpeg9-dev has not been installed & is required by flmsg

ldconfig -p | grep -i libjpeg
libjpeg.so.62 (libc6,hard-float) => /usr/lib/arm-linux-gnueabihf/libjpeg.so.62
libjpeg.so (libc6,hard-float) => /usr/lib/arm-linux-gnueabihf/libjpeg.so

To install libjpeg9-dev

sudo apt-get install libjpeg9-dev

Now ldconfig should display libjpeg.so.9

ldconfig -p | grep -i libjpeg
libjpeg.so.62 (libc6,hard-float) => /usr/lib/arm-linux-gnueabihf/libjpeg.so.62
libjpeg.so.9 (libc6,hard-float) => /usr/lib/arm-linux-gnueabihf/libjpeg.so.9
libjpeg.so (libc6,hard-float) => /usr/lib/arm-linux-gnueabihf/libjpeg.so

Let me know if this fixes your problem.

Sure thing! Ran a little test this morning:

21C (69F) ambient temperature

- 2019-07-31 7:15:45: WSJT-X, Fan, 4% CPU, 39C
- 2019-07-31 7:16:52: Fan off
- 2019-07-31 7:19:15: 50C
- 2019-07-31 7:35:14: WSJT-X, Fan, 10% CPU, 68C (Likely throttling)
- 2019-07-31 7:35:57: Launched CubicSDR
- 2019-07-31 7:37:56: 56% CPU, 78C
- 2019-07-31 7:38:31: 55% CPU, 80C
- 2019-07-31 7:40:35: 63% CPU, 83C
- 2019-07-31 7:41:06: Fan on
- 2019-07-31 7:41:40: 56% CPU, 72C
- 2019-07-31 7:44:32: 56% CPU, 56C
- 2019-07-31 7:45:42: 40% CPU, 52C

This is running on a stock Raspbian image with apps and config set up via the n7nix scripts. Connecting via VNC.

Thanks,

Could you document what SW you are running and what is your ambient temperature?

Also what does top show for cpu utilization?

Re: Point to Point (P2P) email transfer #draws

Basil Gunn
 

For P2P mail using paclink-unix that I've tested with both airmail &
Winlink Express I use a call sign with no SSID. ie. on the listening
side I add an entry in /etc/ax25/ax25d.conf that looks like this:

#
[N7NIX VIA udr0]
NOCALL * * * * * * L
default * * * * * * 0 gunn /usr/local/bin/wl2kax25d wl2kax25d -c %U -a %d
#

To understand what the %args are type: man ax25d.conf

On transmit use: wl2kax25 -c callsign_without_an_SSID
wl2kax25 -c n7nix

In your email client address the Winlink message exactly as you would
when using a gateway. wl2kax25d mimics how a gateway interacts with
the client program.

It's pretty simple & if you leave your client side station powered on it
will always be listening for P2P connections to your call sign.

The only thing you should be mindful of is when composing messages to
send via an RMS Gateway you need to clear them from the outbox using
wl2kax25 before composing any messages that you want to send with P2P
and vice versa.

Hi there,
So after a lot of help from this Group.. (Thanks again Basil !) I have Winlink email setup. I'm learning that other than my email address ( N7KJK@... ) I'm not really using Winlink software. I have both Claws, and Rainloop working as the email client. I tune my radio to the proper frequency for a nearby gateway, then I call it with wl2kax25 -c {callsign of gateway}. There's a modem style handshake process then the gateway accepts my outbound message(s) to whomever, and then checks with Winlink.org on my behalf for anything addressed to me. Works like a charm. This is all dependent on the Gateway having an Internet connection. I'm laying this out very simply in hopes that someone really new is helped out by this brief run down.

So now after a bunch of searching here and on the Internet I'd like figure out Packet P2P.. The scenario is I compose an email to some other Winlink address , but instead of a gateway I know that person has their computer and radio on (and I know the frequency), and I'd like to send the email directly to that station. I'm trying to figure out how I would do this.
In Winlink Express there's a specific session option for "Packet P2P" I just need to emulate that. I'd also like to be the station waiting for inbound email.
Thanks in advance for any guidance.

Re: No WSJT-X transmission with FT-891 #ft-891 #draws #ft-8 #wsjtx

Matt N7ROO
 

Hello Tim,

Sorry about the delay in my response, life took priority!

I've set my width to 3000 Hz and noticed no difference in my ability to send FT8 transmissions between the DRAWS and my radio.

The LAP on the upper left of my radio screen is showing as my LDG Z100 tuner is connected and I believe that the FT891 needs to have the tuner setting (16-15) set to LAMP mode to utilize it. I've attempted to communicate without a tuner as well, but alas, no luck. 

Cheers,
Matt  - N7ROO

Matt,

Also make sure your width is set to 3000Hz
I notice on your radio it says LAP on the screen, upper left
Do you have an amp connected?
Maybe try the radio without a tuner or amp connected.
