RPi-zero 2 W heat issues

Vic WA4THR
 

I have had a Raspberry Pi-zero W for a while for portable digital ops...nice and compact and runs forever with low battery drain, but it is a bit slow. FT8 doesn't get decoded before the next cycle most of the time, making for repeats, and Fldigi just won't run. So, when the zero 2 W came out, I was eager to swap it in the same little case. It is fantastic, FT8 decodes right away and Fldigi loads and runs well...except for one thing. Running only Fldigi and Conky to monitor the processor the heat steadily rises relatively quickly until somewhere past 134F it shuts the thing off. Adding a heatsink helps, but the rise is inevitable and happens within 20 minutes or so, depending on ambient temperature, even with the Pi out of the case.

I could add a small fan, but now I am defeating the size and power use benefit. Note that this problem seems to be only with Fldigi, not any of the other programs like WSJT-X or LinPSK that run cool and work well. So my question is whether there is something I could do like underclocking to control temps when running this program? Any other ideas?

Xiegu G90 + PAT Setup + Rig Control #pi #tnc #pat #flrig

Mérlin
 

Hi Everyone,

I have been trying to get PAT Menu setup with my HAM Pi image on RPi-4 which is hooked up to a Xiegu G90. I have watched these series by KM4ACK to get everything going. Here is the part 3 of it, which talks about Rig Control:

https://www.youtube.com/watch?v=ZCMHeuNjhK0

Unfortunately i not able to get rigcontrol to work properly with flrig. I have made sure i entered everything correctly especially in the .json config file  found here: ~/.wl2k/config.json

I also double checked my settings with the url here.

I also made sure i for the right model(According to Xiegu and many other websites, this model G90 works well when Icom IC-7100 is selected @ 19200 Baud). And this trick of using IC-7100 works no problem with wsjtx and other related software. This model comes out to '3070' when the output rigctl -l is printed to the terminal.  The following is the command i use to start the daemon.

rigctld -m 3070 -r /dev/ttyUSB0 -s 19200

The PTT doesn't work and i dont see any interaction by Pat to flrig when i hit Conect.

So the question i have is, should i try a different model number with rigcontrol?  Has anyone had luck trying to get  rigcontrol with flrig and using pat? I checked hamlibs supported radios page, there is still no official support for the Xiegu G90.

The latest version of flrig does seem to have the Xiegu G90 added in its list of Transceivers, but i wonder if its worth the update if in the end rigctl is not going to support it.  Attached(below) are the relevant screenshots.

There was a QST article a couple of years ago using No machine.  Which allowed two way audio and CW IIRC. Also used Flrig for radio control.

Easy fix.  Re-flash your Teensy.  Everything you need his here: http://www.wvcarc.com/p/tnc-96k-resources.html

Slide JP4 and 3 over and you should be good to go.

Mat,

The lights no longer cycle when powering up (they did before I tried to re-flash).

I’ve attached a photo of the top. 


Thanks!

The solutions for remote amateur radio are enless and simple, using off-the-shelf free software.

Since this is a raspi reflector, ill suggest some ways to do it using a Pi.

Audio in/our for Remote?  Use Mumble or Discord.  Dirt easy, flawless, low latency, and multi-platform.

Rig control?  Use your favorite raspi ham radio control software on the raspi desktop.

Then, use Anydesk to remotely connect.

Boom!  Full remote without a line of code or expense.

Ive been doing remote like this gor years.

This would be used with both FM and HF radios, so the stream to the user
may have noise floor audio all the time.

My thought was to use something like a Pi Zero for the purpose, the
stream would have to be full duplex and use some I/O pins for the PTT.

The remote user would open a web page in a small window with a clickable
on/off PTT button (on a timer for safety) and hot key option. That
should allow use with a smartphone or computer.

This is a minimal budget project (aren't they all?) I don't need
anything fancy like a RigPi.

Thanks for any ideas or suggestions.

Re: Raspberry Pi OS Bullseye has been released..

I think the big point is the Raspberry Pi Foundation actually released a 64 bit OS that isn't Beta.  The link provided was the 64 bit version, not the standard 32 bit build of PiOS.  I'm running it now on 2 Pi Zero 2's, 2 Pi4B's, One 8g and one 4g, and a Pi CM4.
It's not "crippled" with missing drivers and incompatible graphics.

unless he's trying to say that the "No GUI" distro (command line only) accidentally included the GUI interface. But he could have said that.

You can flash it while connected.  Do the lights cycle when you power the TNC up?   Send me a picture of top of the TNC.

Can I program Teensy when connected to Pi

Alan Whitman
 

I had been struggling with getting the Pi and TNC Pi-9k6 (Teensy 3.6) to talk with each other.  I have researched this quite a bit and tried every combination I could find.  BTW, I did enable serial ports on the Pi and they are listed, but they would not connect. 

In desperation, I tried re-flashing the Teensy 3.6.  I did it when it was in circuit with the Pi.  I think that I may have completely stopped it from working by doing this.  Is it possible to do this or am I just reduced to buying a new Teensy?  I will remove the Teensy from the board to re-flash or to replace it with new board.

Any advice will be appreciated.

Hello Michael,

A solution on both client and server is actually more complex than you might think but fortunately, there are several options available for analog FM "RoIP" (Radio over IP) setups:

   - Allstar
      - Server: https://allstarlink.org
      - Client: Any SIP app or the DVSwitch app (https://play.google.com/store/apps/details?id=org.dvswitch&hl=en_US&gl=US)

   - Echolink
      - Server: https://github.com/sm0svx/svxlink/wiki/InstallBinRaspbian
      - Client: https://play.google.com/store/apps/details?id=org.echolink.android&hl=en_US&gl=US


There are other solutions here like IRLP, etc. but they are intended either for repeater to repeater linking or solutions that don't offer a compatible client that offers a simple client solution.


Btw, full time streaming for one client on a Rpi Zero might be manageable but not multiple users.  I would highly recommend to use a faster RPi to give you some performance and RAM headroom.

So you want to commission someone to write your code when it’s already been done? 

Or you want something easy turn key like the MFJ solution?

Or the blog post suggested with step by step instructions? 

Good luck 73

All I want is a window with either a transmit click on/click off or

Re: Simple Remote Radio

duplex audio plus on/off control? like a nice intercom? seems simple enough. 73
