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. 73, Mike

New member Introduction...
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.

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.

Just wanted to make sure anyone interested in the Pi for D-STAR is aware of this project? ?(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.

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.
?
That's a long-established callsign. 1970? Mine dates from June
75.

The default

are pi/raspberry. You can’t log in as root, unless you set a root
password, via sudo passwd. Sudo doesn’t need a

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 All!
?
Just a few lines to tell you what I'm up to.
Having mixed results with my Raspberry Pi.
?
A colleague helped me to load my OS insto a 4Gb SD-HC card. I was having problems because the card slot in my laptop was only good for SD, not SD-HC. Once we'd sorted that out and used an external card reader/writer the OS went in OK.
?
Andrew then told me that we should connect it to the Internet before powering it for the first time. So, with everything connected (composite video monitor to the phono socket) we fired it up and it worked! Andrew went through the initial set-up, downloaded any available updates and made it go to the desktop every time it's switched on. So far, so good!
?
Back at home I tried using it with the HDMI input on our oldish LCD TV. It isn't?Full HD?and the text at start-up is incredibly small and hard to read. When the desktop appears the icons are small, too. Connecting the same TV via the phono socket the text and icons are a reasonable size, but the bottom of the?picture is lost ("off the screen"). This makes playing some of the Python games impossible.?I was able to browse the web, though. I've also downloaded Geany, Python and Xterm following the instructions on a YouTube tutorial.
?
Yesterday (Andrew on holiday) I decided to load the OS into an 8Gb card I had spare. That went OK. Last night I went through the same set-up procedure but didn't want it to go automatically to the desktop. I downloaded Geany, Python and Xterm again (so the Internet connection is working). After doing this I found it was asking for a password, and I hadn't set one. Now I'm locked out of it and I think I'll have to reload the OS.
?
Going back to the previous card, I find I can't access the Internet with it (not found). Grrrr....
?
I've ordered an HDMI to VGA converter which I hope will give me a good, complete picture on my PC's monitor. It cost more than the Pi so it had better work! I've also ordered ten 26-way IDC sockets, five 26-way box headers and 100 feet of 26-way ribbon cable so when I know what I'm doing I'll be able to try interfacing the Pi to something - 100 feet away. No, I'll make a batch of leads for myself and others to play with.
?
I'll let you know when I make any more "progress".
?
73,

I just received a couple Raspberry Pi units and got a couple of cases from Adafruit.
My first plan is to get a DE-SWADJ3 switching regulator from Dimension Engineering so the Pi can get what it needs from a 12 volt battery pack. I will be combining this with a HSMM-MESH node to run as a portable web, D-RATS, and TeamSpeak server. I'm not sure how many users it will support at the same time, my guess is that TeamSpeak will be the bottleneck.
If things go well, I want to move the Raspberry Pi to a dedicated 3 GHz access point for regional HSMM communications. For the price, it can't be beat!
Sincerely,
Chris Arnesen, KU7PDX

Hi!
I've just joined this group. I got my first Raspberry Pi yesterday and with some assistance from a colleague, got it working today. I know nothing about it except how to connect it and switch it on. Lots to learn.
On the radio side, I've held a full UK amateur licence since June 1975. Main interests are 40m CW and RTTY, not that I'm very active at the moment.

Hi. ?I'm John Hays and hold station license K7VE.
I've been porting some D-STAR related software to the Raspberry Pi with good results. ? I have a couple of sample Debian install packages at ?? -- source and project information can be found at?? -- G4KLX just moved the project(s) into this repository and we are modifying the makefile system to support more architectures and packaging systems (RPM and DEB). ?Native builds of ARM are possible with the basic makefile, but I've also been doing cross compilation from Debian 64bit which gives a much faster turn around.
I have used the Pi on a half duplex network gateway for D-STAR for a couple of months and it works well, though may have some floating point issues under Raspbian, I just haven't been able to dig into it yet. ?I plan to put NW7DR repeater's gateway and controller on the Pi soon (at which time I'll probably rehost the packages elsewhere).
Besides the ultimate coolness of the Pi, I am also working on another ARM based board for this code and the armel builds run on both. ?The other board is part of the forthcoming ?platform radio (Disclosure: I am involved with the company behind the UDR56K).
Interested in other projects using the Pi.
