Update: I have fldigi and flrig working. For some reason I needed both to get both CAT and transmit working. Rig is IC-746 which has a CAT command for TX. I have VNC working and can remotely connect to my raspberry pi 3B+. From what I understand the new MFJ-1234 uses a program called mumble for VOIP. Do you know of any how to videos to install it on my pi and on a windows laptop? I plan to use a cheap USB sound dongle to get TX/RX audio to USB. Ken
I'm running two raspberry Pi's on my desk, the ambient temperature in my office is 28 - 29 C. The consequence of this is I've burned out both of them. Be sure to install the heat sinks and duel fan on the CPU to keep it cool. Just a small caveat. After I replace both of my Pi's I'll do this configuration. Thanks, very much. 8P6RC
Where do you buy your cables. To connect my 706 to my new pi I need a din 12 pin x usb 2.0 correct? Then I think I can use a pi program instead of a signallink, correct. My ģoal is to operate very portable and soon replace the 706 with something very light weight. Thanks John
No, you still need an interface to convert the audio to digital samples. Like a USB sound card. But before you buy a signal ink, look up DuinoVOX. My USB interface you can build for around 25 to 30 bucks.
Can you recommend a site with Ham Radio projects using a Raspberry Pi. I am looking for something like a Heathkit approach. All software written with simple download to sd card and run similar to the MMDVM hotspot project using Pi-Star. I always wanted to try some Raspberry pi projects but held off due to the software instructions. Every time I look at a project its always at a level above what I know software wise preventing me from moving forward with the project. The only project I have every done is the MMDVM hotspot which worked perfectly first time. If your good on QRZ I can email. Thanks, Ken
I have my pi, flrig and mumble all working great. What I would like to know is of a way to connect not using VNC but any web browser and a IP address making the pi a web server for the connection part. I am hoping this would also work on a cell phone offering a better viewing experience. flrig on a cell phone using VNC is difficult to use.
Well, if you're SSHing into them, then you have the IP address. Hook up a monitor and go to the VNC icon up on the menu bar and check it's settings. There's one setting for verifying an attempted connection. If that's on, then you can't connect until someone at the pi clicks ok. That would stop remote connection. That's my guess as to why it's not working for you. You also need to be running the latest raspian.
Great vids, all sorts of useful info! Question. . . have you tried using VPN to connect to your home site remotely from the outside world? Connecting via VPN and using Remote Desktop works great over here; fun to sit in a park and connect back to the house and play radio.
I followed the instructions in this video and got the connection from my Win10 machine and tablet to work. I also have Linux Mint set up on the same machine but could not get gnvcviewer or vinagre to work at all. They connected and then instantly disconnected. Only after going to the realvnc website and downloading the deb64 version of the linux client and installing that could I connect to the PI. If anyone runs into the same problem perhaps they should try this solution.
Nah, just open your ssh with keys configured. There absolutely no problem. Also you can do SSH tunnel and use ssh from that, so you get encrypted connection.
Hi. Please can you let us know whether VNC tunnels audio to and from the pi? I would like to be able to use a headset on my local computer for 2-way audio to/from the remote radio. I propose to use grig or wfview (for icom) to control frequency, ptt etc. Thanks.
VNC just does video. There are ways of moving audio over a network connection using Jack or Pulse Audio. Wfview will bring the audio across when you're remote controlling an Icom though.
I've decoded the Teletext POCSAG systems of the nearby hospitals. They need to train their employees on what type of information they shouldn't send over these cleartext systems! Addresses, phone numbers, and even the occasional SSN. Not good.
*Another cool thing you could do with this is to connect the rpi and sdr off a battery and put in up in a tree with the antenna plugged directly into it with no lossy feedline going from the tree outside into the house. I have been asking people on electronics forums how to do this for a while (remotely control mySDRPlay with it plugged into a raspberry pi) Can I use VNC with a windows computer into the raspberrypi on the other end? VNC is just a program that is kind of universal isn't it? I was trying all sorts of ways to wirelessly control the pi and none were successful.*
You can also try VNC Viewer for Android phones and tablets. I'm working on a uBITX, RasPi and an 8" Android tablet as a portable option for camping etc.
Thats awesome! You could put it in a little fold out case with tablet on top. Do you have a youtube or website documenting it? If not you could set up an account on www.eevblogforums.com And people would help you trouble shoot as you do it. The people on those forums can collectively fix make everything.
If that was directed at me Dave, I don't have a website and don't do videos for TH-cam etc. but would gladly answer any questions that I can. So far I have the RasPi up and running with the HAM related packages installed as well as the tablet connected through VNC over Bluetooth. I've just received my uBITX kit and will start assembly as soon as a few other parts arrive....still waiting on a Nextion 3.5 display, case and power supply. Slow boat from China thing...lol
So VNC can go over something as low bandwidth as blue tooth? I always thought blue tooth was limited in that respect needing at least an internet connection. Doesn't VNC look for an IP to connect to? What does a Bluetooth connection "look like"? I thought in the video he talks about DHCp servers so they are wifi not blue tooth. Can you point to any site or videos on general info? Thanks this is something I have been playing with for a while but kind of gave up thinking it wasn't possible or not for the average hobbyist.
I saw a board that goes under the Pi that will do 2 hard drives. Is there a real need for this? I looked around and found enough boards to make it almost as strong as a laptop. How much of this is needed to make it work with my radio?
The default filesystem is EXT4, which is journaled. A journaled file system will greatly reduce the possibility of corruption with an unexpected power down, but not prevent it entirely. The way flash memory works, entire blocks of the storage are re-written, even if only a few bytes are changed within that block. If power down occurs during a re-write of one of those blocks, all of the blocks contents could be corrupted or lost, destroying several parts of the filesystem.
They probably wrote some html and othe custom code to wrap up several open source projects. For example, pulse audio can be used with jackd to route audio over networks.
RemoteRig, have You heard of that. It's a swedish Remote control box. Just suggesting and I have nothing to do with the manufacturer! 73s de Gunnar sm6oer >>\
Love seeing things about the PI (though I don't have one - yet). Thanks! Have you checked out Q4OS for the PI? www.q4os.org/downloads1.html Altho it is Orion instead of Jessie.
No, I hadn't heard of it. Surprising to see it's using the KDE desktop. Not very many still running that. I tried KDE once and it was really buggy. I'm sure it's better now, but development has nearly stalled on it. I'm not sure what it would offer over the current raspian.
I really couldn't say about the advantages/disadvantages since I don't have a PI. I do run Q4OS on my desktop. Some of the people that try different os's say it is lighter weight that Mate and other "light" versions of linux. Being debian it of course has synaptic. Just thought you might want to check it out if you ever get the time.
Any will work, with the exception of the Pi Zero. Although it might be usable with a USB hub. Performance will be best on the most recent, but I have run fldigi on the earliest version with success. The latest versions have wifi built in, older versions do not.
Bout 3 months old. Running Raspian and Ubuntu both. Ended up keeping Ubuntu due to it's default use of the analog audio port. They were both clean installs on a C10 SD card. My biggest issue was that it sat idle for more than a few minutes there was quite a lag before it responded to any mouse clicks. Decided to give it to someone who is more into experimenting.
It's headless because there is no monitor, or keyboard, or mouse attached to the pi. It's remotely accessed over the network via screen sharing. That's a standard description in the I.T. world for such a configuration. So I'll not be following your orders and will make no changes.
Looks like you installed the GUI version Of Raspian. Most similar videos show this in the command level version. Glad you showed it this way.
Incredibly useful and clear run through Kevin, thanks very much.
Thanks for sharing your journey with the rest of us !
This would also be awesome to add a community HF radio to a HAM Mesh network. Thanks for the video, this is great
Thanks for another superb and informative video Kevin. We share an interest in RasPi, IC-7300, Ubuntu and RVs.
This is fantastic. Great content. Now I know what I am going to use the raspberry pi I have sitting on the bench. Thanks
Great, as usual!
I've seen articles on using the Raspberry Pi to make any printer a wireless printer.

Great value video!!! This is gold. Thanks a Lot!! 73 CX1GU
Excellent video! Thanks!
Excellent. SSTTP. Thank you for the video.
Def VPN and use anywhere. They work great. Get the Pi 4 its faster.
, , , great , GREAT STUFF ! ! ! Thanks Kevin . .
Thank You VERY MUCH Kevin =)
Hi Kevin,
Great informative video. I'm going to have to teach myself about Linux, after I solve my dad's problems. 73 WB3BJU
Thank you for making this video. I have 2 remote pi’s running via ssh but I never go VNC working. I will try a fixed IP address and see if that helps.
Well, if you're SSHing into them, then you have the IP address. Hook up a monitor and go to the VNC icon up on the menu bar and check it's settings.

Hi Kevin Thank you for the video enjoyed it
Another great video, very informative. Now I need to make an interface for my 818. Thanks Kevin. 73 VK4YST
They don't cost much. Have a look at my DuinoVOX.

Nice demo.
Have you thought about DMR or POCSAG decode with a RTL-SDR dongle as the receiver?
I've decoded the Teletext POCSAG systems of the nearby hospitals. They need to train their employees on what type of information they shouldn't send over these cleartext systems! Addresses, phone numbers, and even the occasional SSN. Not good.
Yes, POCSAG is like running WiFi with no encryption.
I meant to add earlier decoding DMR or pagers with a Pi and dongle(?)
Can you do a video on this? I have been trying to do this for a while but don't know where to start.
I just did a video on decoding pocsag recently.

RealVNC is a free VNC viewer for windows. It works fine for connecting to a Pi.
You can also try VNC Viewer for Android phones and tablets. I'm working on a uBITX, RasPi and an 8" Android tablet as a portable option for camping etc.

None. Just a pi, sd card, and radio interface.
Can't you change your file system to a journaled system to prevent file system corruption during hard shutdown?
The default filesystem is EXT4, which is journaled.
A journaled file system will greatly reduce the possibility of corruption with an unexpected power down, but not prevent it entirely.
The way flash memory works, entire blocks of the storage are re-written, even if only a few bytes are changed within that block. If power down occurs during a re-write of one of those blocks, all of the blocks contents could be corrupted or lost, destroying several parts of the filesystem.
Have you any info for a do it yourself RigPi? (MFJ-1234) I would be surprised if no one else has tried making one of these using VOIP.
They probably wrote some html and othe custom code to wrap up several open source projects. For example, pulse audio can be used with jackd to route audio over networks.
I bet someone comes up with an open source project similar in function soon enough.
RemoteRig, have You heard of that. It's a swedish Remote control box. Just suggesting

Kevin Loughin mine is one of the generations
Good info but I must have a bad RP. Takes about 30 seconds to boot. Oh well...
How old is it? How much is running on it? What os? Have you tried a clean new os?
Bout 3 months old. Running Raspian and Ubuntu both. Ended up keeping Ubuntu due to it's default use of the analog audio port. They were both clean installs on a C10 SD card. My biggest issue was that it sat idle for more than a few minutes there was quite a lag before it responded to any mouse clicks. Decided to give it to someone who is more into experimenting.
So this is headless coz you use GNU/Linux desktop but without a monitor ?. Change the title or redo the vid and use CLI
It's headless because there is no monitor, or keyboard, or mouse attached to the pi. It's remotely accessed over the network via screen sharing. That's a standard description in the I.T. world for such a configuration.
So I'll not be following your orders and will make no changes.
