Matt et al, the existing ax25 utils are good but confusing, I am working on a simpler interface and hopefully can produce something useful in about a month. I am also planning to include a 44net option if possible.

Hello, all.

I'm Matt, KC2O, from San Francisco, and I've been interested in developing a platform for a low-cost, low-power packet-based emcomm BBS system.

I have a fair bit of experience with PIC and Arduino-based projects, but neither of those seemed to be sophisticated enough to do what I think is needed. Combining RaspberryPi with a TNC-X (or customized equivalent) will be perfect.

(Incidentally, I just rebuilt the AX.25-including bootc kernel to support my wifi usb dongle, by following Dominique Gallot's excellent notes here: http://www.gallot.be/?p=150.)

While I have a fair bit of experience with Linux, I'm new to packet, and look forward to getting help from this group.

Database of RPi Ham Radio Applications

n6ws
 

All,

I'm new to the group, but I would like to suggest beginning a database of ham radio applications for the Raspberry_Pi_4-Ham_RADIO Group. The database could contain information on various applications that have successfully or unsuccessfully been ported to or installed on the Raspberry Pi platform.

Application - Name of the application
Type - A descriptor of the application (Satellite, RTTY, JT65, etc.)
Website - URL of the application
OS - Flavor of OS & Version (Debian Wheezy, Android 4.0, Arch 13-06-2012)
RPi - Version of board (B-256, B-512, C-1G, etc)
Successful - Yes, No (Successfulness of installation)
Members - Members having installed application
Additional Instructions - URL for RPi installation instructions
General Information - General information

Would the group members find this information useful?

73, Bill

Hi all, I'm Paula G8PZT and I don't yet own a Pi but would very much like to :-)

My interest is in writing software for data-over-radio networking, VOIP, and SDR. Also have emcomms in the back of my mind.

I am hoping to port my applications to the Pi, so I can junk the power hungry and space wasting PC's that power my packet systems and VOIP repeater. I'd also like to develop new applications to take advantage of this exciting little device.

I have very little experience of Linux, being mainly a spare-time DOS and Windows programmer (asm/c/c++), but I'm hoping this device will finally give me the push I needed to get my apps ported to Linux.

Now I just need to buy one, or more... ;-) [I was told there was a big waiting list, so I waited for the rush to die down]

Yet Another Welcome message

Jerome K <JKutche@...>
 

The new members has been growing rapidly...

I try to check several times a day to approve if you know anyone who believes they have waited too long pop me an PM here...

I wanted to drop a hint and others are welcome to do same..

Todays Hint for anyone new to the RPi... Never plug anything into the USB portthat draws more then 100mA or any combination... Use a POWERED HUB instead.. You should also go here and check the Peripheral Compatability list... www.raspberrypi.org

Happy experimentation to everyone...

73 Jerry N9LYA


PS I am looking to use my 4Pi as Ham Radio tools. Like Nodes, possibly even some RF Networking linking... anything that can be imagined.. I would even consider owning a dozen or so of these if I could do some really cool things.. The RPi sounds like its only limitations will be the imagination..

Anyone needed a SD card Imaged for their Raspberry... I would be glad to do so just for return shipping charges... I use USPS Priority Mail. There is software available for anyone wishing to do so themselves.. Some is Linux Based another (the one I used is Windows Based. I did it and I did not know the first thing about it... That same info can befound on the Above websites download page.

Hello, My name is Mike, VE3YXA. My situation is opposite to Eric's, I am in Arizona right now.
I've got my RPi in July, too, and now playing with Raspbian and RaspBMC.
The project I have in mind is meteor radio reflection monitoring (see www.rmob.org). At the moment I have a setup with a VHF Softrock and an old laptop. It is running 24/7/365, so power consumption is a real concern and RPi is a very attractive option for this kind of project.

Hi All,

My name is Eric, I'm KC7KLZ. I recently acquired a Raspberry PI. When I found out about it, I had been playing with an Arduino uno. I was doing simple things like flashing morse code on LED's and other things just to learn what it can do. Then a friend of mine from work showed me the Raspberry PI web site. Since then I was drooling over it. I put in the purchase request for it last March. It finally arrived at the end of July, and I was able to pick it up a few weeks ago. I've currently successfully placed an OS on an 8 gig SD card. I've got SSH working so I can remote in via my Mac or Ubuntu box, and I've got tightVNC working so I can run a remote desktop on it. (I can hook it up and run a GUI via my Ubuntu box.) Both of these took some time and effort.

My first project I'm looking into is to set up TCP/IP over the AX.25 protocol. I would like to see if I can get a small e-mail server, HTTP server, and a IRC chat server going. The goal would be to create a small form factor packet interface that I can plug into a router, and be a backbone to communicate with a similar setup via a packet link. You will not be able to send huge stuff, but simple text messages, e-mail messages, and small web stuff would be perfect for ECOM usage. The nice thing is the whole thing is DC and can be set up to run off of batteries.

Introduction, new member

Juan A. Bertolin
 

Hi to all,

First at all, thanks to Jerome for accepting my request to joing the group.

I was aware of the Raspberry Pi through a friend and now I am waiting to receive it. I think it will help me to achieve my project.

Due to personal location restrictions, I need to control remotely my ft817 (it will be located in another room of my house... I lost my ham radio room!), Automatic Tuner will be coming later on (I know that Elecraft T1 is managed by means an Arduino, I hope RPi will be able to make the role too).

I am using now a Ubuntu distribution in one of my laptops close to the ft817 and connected using hamlib (rigctld) and the audio with SJPhone for linux. On the other side, a MacOsx Mountain Lion with hamlib, fldigi and SjPhone too connected to Linux environment by LAN (wifi). The goal is being able to control and operation (just CW) of my ft817.

The second phase is replacing the Vaio with Ubuntu Lucid (10.04) distribution with a RPi. If it works, I will be able to move the whole station further away to a better position to make radio at lower cost as possible.

Thanks to your comments, I am preparing all the minimum stuff list to setup the RPi (I hope moving from UBuntu to RPi will not be a pain, once all the programs will be able to run -now there are some troubles yet-)

I hope, I will be able to share with you my experiences and results.

D-STAR and Raspberry Pi

 

Just wanted to make sure anyone interested in the Pi for D-STAR is aware of this project http://developer.berlios.de/projects/opendv  (The Repeater and Gateway run on a Pi just fine, though the soundcard version hasn't been tested by me.)

Be aware we have found that it's important to have user built software use the same floating point (hard - armhf or soft - armel) as the distribution (kernel and libraries) they will run on.  Otherwise you get bad calculations.

Re: Some progress

 

Also, the Raspbian has a built-in tool to extend the partition on first boot up.  It works fine and saves the multi-step manual process if you are running something bigger than 2 GB.

Hello John,
 
Thanks very much for the explanation. I'm not sure whether I can overwrite what's on the card with a new installation of the OS, or whether I should load Linux into an old PC to get at it that way, or just buy another SD card. Last option is quick but not very educational. I'm a Linux novice and not finding it at all intuitive. Can you recommend any literature?
 
I'm interested in your packet node project. I have a KPC3 (bought new) and a KAM (bought at a rally for £25 - bargain!) but never got into packet radio when it was new, which I now regret. I have VHF radios and laptops to spare, so I ought to try again.

John,

 

The default user/password for the standard PI distributions (wheezy and raspbian) are pi/raspberry. You can’t log in as root, unless you set a root password, via sudo passwd. Sudo doesn’t need a password.

 

The SD card has a small boot partition, formatted as a FAT partition, so can be seen by windows. The rest is ext4, which windows can’t see, So a freshly loaded image appears to windows as around 55 MB. When first booted, it will only use the first 2 GB. The first time you log in it should run a utility raspi-config, which allows you to resize the root partition to fill the card.

My main interest is in using the pi as a packet node. The prototype TNC is shown on the front page of this group. This is a standard TNC-X, with a bit of stripboard superglued to the edge to carry a 26 way connector. I’ve designed a board with the connector on board, and the same size as the pi. I’m waiting for the boards to come back from the PCB factory. The board is stackable, so more than one TNC can be connected, and uses the i2c bus to communicate with the pi.

Hi again,
 
Having somehow locked myself out of the second OS installation (it's demanding a password, which I didn't set) I decided to format the 8Gb card and reinstall the OS. My laptop now reports that it's a 55.8Mb card. Any suggestions?

My box of bits arrived yesterday. The HDMI-to-VGA converter works a treat. I can read all the text on the computer's monitor (when it's not moving too quickly) and have a full view of the games screens.
 
The 26-way connectors and cable arrived too, so I can start making leads for the P1 GPIO header. First job; flash an LED. Second job; flash it in Morse!
