Re: Fans, Pi4, and the DRAWS case

Steve Stroh
 

It's a personal perspective, but I don't want a fan on an appliance
like a DRAWS. Fans are noisy. They suck dust in and spray it all over
the board. They're non-static hardware that will inevitably fail.

I hope to build up my DRAWS units as (silent) appliances, and tack
them up and out of the way on a shelf, or wall, or ??? and access them
remotely.

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.

Thanks,

Steve

Re: FLmsg does not launch on DRAWS

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.

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.

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@Winlink.org ) 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

Do you have an amp connected?
Maybe try the radio without a tuner or amp connected.

Fans, Pi4, and the DRAWS case

Chris Metcalf
 

Not to throw a wrench in things, but will there be a provision for adding a fan to the DRAWS case?

I've been experimenting with my Pi4, and unlike the Pi3, it runs quite hot - hot enough that the little Pi3 style heat sinks aren't enough to keep it from going into thermal throttling mode and slowing itself down. This has been documented in early reviews: https://www.jeffgeerling.com/blog/2019/raspberry-pi-4-needs-fan-heres-why-and-how-you-can-add-one

I bought a cheap plexiglass "ice cream sandwich" case (https://www.amazon.com/gp/product/B07T3DRB1C/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1) and modded it with taller risers to accommodate my DRAWS hat. But even its open design didn't allow the Pi4 to cool itself when it was loaded up, and I quickly hit 80C and started seeing performance degradation. 

I zip-tied the small fan that came with the case to one of the risers, blowing across my heat sinks, and the temperature quickly dropped down to 40C and stayed there. 

I'd still rather have the protection of the full case, but I'd be worried that it'll turn into a little metal sauna...

Re: APRS Messenger

Don--AE4DW <dwinflorida@...>
 

I own multiple Atomic Pi boards, having joined the kickstarter and then acquiring a couple more later on. I'm not an SBC guru (nor a linux development guru) by any means, but I have no complaints about the board thus far.

From a marketing perspective, putting the "Pi" name in there did them a disservice, as it is in no way a pin for pin replacement for the RPi.

While the hackaday article is a bit over the top, IMHO, its a solid board, but should be understood that its a "repurposed" board, not a ground-up design, so its not like they set out to rival the RPi with an Intel chip. It also explains the whole adapter board controversy and why the board is how it is. It seems like that was the Hackaday beef..that they didn't clearly put it out there that these were boards intended for another application, surplused, and then sold to the kickstarter entrants. To me, that speaks to good business sense, not some deep dark conspiracy and a planned scam. For what its worth, the group running the kickstarter ran one of the most efficient and responsive kickstarters I've ever been involved with.

I'm just becoming acquainted with the DRAW, but at first glance, getting it to work with the APi might be possible, but most definitely not, plug and play.


Re: APRS Messenger

Steve Stroh
 

Donald:

Wow - that was illuminating! The Atomic Pi did sound too good to be true, especially when you needed an adapter board to power it reliably. 

OK - take the Atomic Pi out of discussion. 

Scott Currie NS7C said it best. Paraphrasing, some basic Amateur Radio software runs only on Windows. Get over it. Buy a cheap Windows tablet, or laptop, or a basic cube (one was recommended in the referenced article) and just treat it like an appliance. Scott is a smart guy.
