Thanks to this post I was able to get fldigi updated to 4.0.18 on my machine.

I am new to the digital modes and to Linux, a combination that has caused much head-scratching and muttered expletives. 

These instructions saved my bacon! Thanks and 73s

Hi Dave,

This is correct. In fact, I now have fldigi open (radio on, linked to the Pi/fldigi via CAT) and Chromium with three tabs open (including the one I am using to type this message) plus htop to monitor the system. The CPU is running at 22% average load. 582MB of memory out of 927MB are used and Load Average readings are 0.97; 1.49;1.33 - pretty good. Only 10MB are used out of the 1GB swap file.

The system starts feeling some pressure when I open pages such as pskreporter.info and aprs.fi. When I do that, the CPU load goes up considerably and it can remain at or close to 100% for prolonged periods of time, with consequent CPU temperature increase. I don't know if it is the demand for graphic processing power (screen resolution is set to Default, Preferred Monitor Settings, judging by the image quality I think it's pushing it to 1080) or the slow-ish WiFi connection from this point that causes this or if it is something else. I have somewhat improved things by increasing the GPU memory from 64GB to 256GB, I could go higher but how much can the GPU memory be sensibly pushed on a Pi?

Meanwhile I am looking at the Latte Panda suggested by KD6IL and also see if I can install a dual boot Mint Linux on my old laptop - I won't be using the old Dell laptop for this purpose but it will still be nice to have Linux on it.

There's a snazzy device called a Latte Panda. It's a pc and an Arduino on one board. 

Mouser sells the boards. DFrobot sells the wood case (or plastic). Get the ballbearing fan. Or not. I have the 2G RAM version and it runs Windows 10 just fine.

Good morning Raul,

Let me share a very recent purchasing experience at the Huntsville Hamfest.  I purchased a Lenovo ThinkPad notebook E540 i5-4200u for $175 (US).  The machine specifications included:
  • 2.5 GHz 64 bit i5 processor
  • 4 G Ram
  • 640 GB SATA drive
  • Windows-10 Professional
  • 3 USB ports (2 @ 2.0, 1 @ 3.0)
In less than 4 hours I
  • installed Mint-Xfce / 64, distribution 18.3 in a dual boot configuration
  • followed the fldigi wiki for Mint builds, installed and tested
    • fldigi
    • flrig
    • flamp
    • flmsg
    • flaa
    • fllog
    • flcluster
    • flwkey
  • installed and tested the same programs on the Win-10Pro partition.

Mint-18.3 recognized all of the Lenovo hardware including the onboard wifi and blue tooth.

My transceiver is an IC-7200 with a single USB port (hub) for both serial CAT and Rx/Tx audio.

I build and test all of the programs on a Pi3 and I never experience the 100% cpu load that you reported.  fldigi usually runs between 15% and 40% depending on which modem is selected.

73, David, W1HKJ

Thanks everyone, David, Ed, Marty, et al.

I haven't shelved all this, it's just that my week has been quite busy with little time (and enthusiasm) for computer work. My conclusion from this conversation and the experience I am gaining from using the RasPi for ham radio use, which in my case consists of using fldigi, the browser pointing to some content-rich pages on multiple browser tabs, is that the Pi 3B+ tends to feel a bit stressed, with the CPU often running at 100% load and warming up to about 72 C when in constant use.

I believe I could make an improvement through some configuration tricks, however my general impression is that the hardware is somewhat near its limits. But I like the idea of having a Linux machine running and to be used to experiment and learn, so I am looking at alternatives and the options I have in mind are either a more powerful SBC such as the Odroid XU4 or a barebones PC such as a Gigabyte Brix BXBT-2807 (the latter's specs would include 4-8GB RAM and a 128-256 GB SSD drive for speed). The cost, within reason, wouldn't be an issue and given that I'd like to have some more oomph and flexibility, barebones are what I am really looking at.

When choosing, is there anything I have to avoid, which would prevent me from installing well supported Linux distros or limit the performance? I trust that fldigi and accessories can be compiled and installed on pretty much any distribution and my concern is hardware compatibility. The final configuration would be the PC, wireless keyboard/mouse, HDMI screen, direct USB connection to RTX and if the required supply is 12V I have plenty of Amps available from multiple power supplies so it would have its own dedicated PSU. I have no idea about what Linux distro to install but I worked with both Debian-based and Red-Hat based so I would be happy with either, though by browsing the web I see that most amateur support pivots around Debian-based systems so that could be the best suited choice for these applications.

P.S.: you were right about the power supply, there was a voltage issue too as it produced 4.98V. I now plugged in a more robust unit - so far so good, no crashes under the most demanding conditions I managed to create.

Hello group,

I'm running 4NEC2 through WINE in Lubuntu, and the program works great.

I'm having a "duh" moment though, and can't find where in the program I set what material the elements are made out of. I'm designing a bunch of VHF and UHF antennas where some elements will be copper while others will be aluminum.

Hello Raul, Marty,

I have tried on my Pi2 B+ to use the pi user and found that I had some
issues I was able to get around them, but found it easier to leave the
pi user as the Root id and to create my own id, such as my initials
or my name, to log in the create my build environment.

There is no reason why getting the fl-suite running under the "pi" won't work but I *would* argue that it's a good security practice to NOT use the "pi" account.  It's a well know username (kinda like root, admin, Administrator, etc) which are accounts that all attackers will start with first.


Like David I believe you need a better more capacity power supply to power your Pi 3 +, I also have bought and use with mine a powered USB
4 port hub to use with mine to relieve the stress on the Pi's power

An excellent recommendation with the key point being that the hub is powered (aka.. comes with it's own power supply). 

Btw.. not all USB hubs are equal.  Some improperly made units do "backpower" which can confuse the powering situation and even damage your Raspberry Pi:

Hi Robin

Another thing I do which I learned way back in the good old days of
Unix admin, was to allow twice as much swap space as the amount of
memory in the system, so with 1GB of memory on my system I allow
2GB of swap space. I know the Ubuntu instruction say same size,
I just don't see why not a little extra.
All of my PC's have over 300 gig of disk drive so allowing for
at least 2 times 20GB for two root partitions isn't a good thing to have.

I also like to have a bootable DVD for each of the two OS versions
I have to allow for a reload if needed.

Back in the day we had two rules:
One - back up your system regularly.
Two - Don't break rue one.
And those were the days of tape real to real system backups. Time
consuming yes, but in the long run a real time sayings if a reload
of the OS was done from scratch.

Ok I am going to jump in briefly. If you are using fldigi then the

Correct. I have done this and it works well.
On the Raspberry PI you maybe should create a user and put that id
in the dialout group. The pi user will work but it has root control
I believe.
I do have another user available and would be happy to transfer the use of fldigi/flrig to that user. Does this mean that if I add the other user to the dialout group I'll then find the fldigi configuration in the new user profile?
Yes, when that new user has logged in under that environment the build
will be done under that file structure with that users ID and permissions. With this new user ID and following the build instructions
for the PI from the wiki on the web site:

http://www.w1hkj.com/doku/doku.php?id=howto:main

under the "Building from source header, the first one for
"Building on Debian, Ubuntu, Mint, and Pi3"
I have used these instructions for many builds, they are very complete.
They work for all of the Fl-suite of applications.

I believe David as said that starting with Flrig first and getting it
to connect with you rig and functioning fully before moving on to
Fldigi.

I have tried on my Pi2 B+ to use the pi user and found that I had some
issues I was able to get around them, but found it easier to leave the
pi user as the Root id and to create my own id, such as my initials
or my name, to log in the create my build environment.

There are instructions as a wiki on Dave's web site for building on
Debian and Raspberry PI that gives the how to very well. I can't
remember if you said you had those or not.
I am going through one bit at a time. The problem is that I probably need to read from the beginning to the end, which I haven't done so far as I was trying to patch the system on the fly.
Thanks for the comments.

Like David I believe you need a better more capacity power supply to power your Pi 3 +, I also have bought and use with mine a powered USB
4 port hub to use with mine to relieve the stress on the Pi's power
supply. My supply is a 5v at 2.1 amp, but if I use the four ports on
the Pi for things requiring power I thought it wise to relieve some
of the stress by putting my sound USB card in the powered USB unit
and use the on board USB ports for Keyboard and Mouse.

I hope this gives some more information, and is a help.

I will now leave you in the capable hands of David he has helped me
in the past getting started with my Pi2B+.

Hello Andrey,

Ok, understood.  NO, the TNC-Pi cannot do PSK31.  To do PSK31, you only need a an inexpensive USB sound device such as:


DIY:

   - Syba SD-CM-UAUD :: https://www.newegg.com/Product/Product.aspx?Item=N82E16812186035&ignorebbr=1&nm_mc=KNC-GoogleAdwords-PC&cm_mmc=KNC-GoogleAdwords-PC-_-pla-_-USB+Converters-_-N82E16812186035&gclid=EAIaIQobChMIhOKbpPH53AIVBMpkCh0V5wlmEAQYAiABEgIRX_D_BwE&gclsrc=aw.ds

   - To key up the radio, you can use one of the GPIO pins on the Raspberry pi and a simple transistor circuit


If you want something more pre-built, consider:

   Signalink
   RigExpert
   West Mountain RigBlaster Advantage  (I don't recommend the PnP or any other unit that doesn't include it's own sound device)
   Timewave Navigator

   Many others:  https://www.gigaparts.com/products/software-and-pc-interface


All of these are complete units with sound card isolation and other nice features.

KLog 0.9.4 is finally[1] here and it brings one interesting new feature and one important bugfix.

Now it is possible to send QSO data directly from WSJTX to KLog and KLog will update it in the QSO entry or log the QSO sent from WSJTX.
It will really save time for those of us using WSJTX!

In addition the translations for Catalan, Croatian, Danish, Spanish and of course English, have been fully updated.

Find below the Changelog.

August 2018 - 0.9.4
- WSJT-X support to receive logged QSO and realtime data.
- Check bool DataBase::updateTo012() / it was always returning true without any action.
- Syncronize RX Freq with the satellite downlink combobox.
- Focus is back to search line edit when right click on the list of found QSOs.
- Update process has been improved.
- Some warnings removed from compilation time.
- Bugfix: Date was not properly calculated and UTC settings was not applied. That may create wrong date QSO when date changes due to UTC (TNX AC1DW).
- Bugfix: When adding a QSO, if the QSL is marked as received, KLog showed a SQL error.
- Bugfix: Table qsl_via needed to be renamed (TNX EA6ZS).
- Bugfix: Some DXCC status were nor properly calculated.
- Updated translations: Catalan (TNX Josep), Croatian (TNX M0NKC), Danish (TNX Joe), Spanish (EA4TV).

You can download KLog from:
http://www.klog.xyz
Please wait some time if the browser returns a file not found error. It may be caused due to the mirrors need to update. The process could take up to 24h!

[1] KLog 0.9.4 took around 7-10 days to be released due to the fact that my laptop was broken. Today my development laptop has a broken screen and it is quite difficult, event to write this email so just imagine doing the final testing and packaging X'DDD

(VERSION EN ESPAÑOL)
KLog 0.9.4 ya está aquí [1] y trae una nueva funcionalidad interesante y el arreglo de un error importante.

Ya es posible enviar datos de QSO directamente desde WSJTX a KLog y KLog actualizará esos datos en la pantalla de  entrada de QSO o bien, enviar los QSO realizados directamente desde WSJTX.
Esta funcionalidad ahorrará tiempo a aquellos que usamos WSJTX.

Además, las traducciones a catalán, croata, danés, español y por supuesto inglés, han sido actualizadas completamente.

El Changelog con los detalles está únicamente en inglés más arriba...

Puedes descargar KLog desde su página web:

moderated Re: fldigi and rigCAT on Raspberry Pi

David Ranch, KI6ZHD
 


Hello Raul,

I tried both options, i.e. I tried using rigCAT with the file in the wrong place which caused fldigi and flrig to lose configuration,

I don't know how to put it any other way to make you understand... RigCAT support in the Fldigi program and Flrig are COMPETITORS for rig control.  I personally recommend to use Flrig.  If you agree to that approach, STOP trying to use the RigCAT support in Fldigi.


I tired to put the xml file in the right place, which makes fldigi work as intended but flrig not to sync with the radio;

See above.  You cannot have two competitors trying to control the same radio


This is what I have done now. Open fldigi, set it to use flrig, saved, closed. Open flrig, set all the transceiver variables as required, i.e. Rig IC-7100, port as the correct one as instructed by you and Ed, 19.2k baud (which works fine) all the rest as default i.e. RTS/DTR 12V and PPT via CAT - could it be this last bit via CAT that upsets the system? Or can it just be a silly thing such as having to press "save" somewhere?

There is no such thing as "save" in Flrig as it saves everything once you exit the program.  If it's not saving your config, I bet you have a file permissions issue.  Try running the command:

   ls -la $HOME/.flrig

On my system, this is what I see (your results will be different as I've modified my Flrig setup) but the important thing is the ownership details:

The whole Pi. I now have replaced the PSU with something else and a better cable, I doubt it can supply 2A, it probably can push 1.4A, I will measure it sometimes over the next few days. However I had no more crashes since, even when I open very challenging web pages (for the Pi and the slow network it can use in the shack) such as pskreporter.info.

1.4A will *not* be enough to run a Raspberry Pi 3B+.  The Raspberry Pi documentation is very clear about this and you should count on getting more crashes.  Please note that crashes on the Raspberry Pi can corrupt the SD card.  At that point, the OS might become broken and not boot/function properly.  You'll then need to start over.


Ultimately, I see that Linux works quite well with these applications. I am now thinking of installing it on the old laptop, it looks less resource-hungry than Windows 10 and this element well "rejuvenate" my old machine.

Absolutely!  Different Linux distros have different resource requirements but depending on the old laptop resources (CPU, RAM, video card, disk), I'm sure you'll find something to your liking.

Hello Andrey,

I have Raspberry Pi 3 B+ and got TNC-PI 2

When you say TNC-Pi 2, do you mean the TNC-Pi9k6?   Regardless of which version, this won't work.  Both the TNC-Pi unit as well as the Fldigi program acts as the modem and you can't have two modems.

What are you ultimately trying to do?  Do AX25 packet or do other various data modes (PSK31, RTTY, MFSK, etc)?
