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 NW7DR -- source and project information can be found at Berlios -- 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 UDR56K platform radio (Disclosure: I am involved with the company behind the UDR56K). Interested in other projects using the Pi. I occasionally put related information on my blog. 73 de K7VE

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. 73, John G4EDX

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

I see we are up to 27 members.. Please post something about yourselves and what you plan for your Raspberry Pi projects or what interests you about the Raspberry Pi.. Thanks have a nice day.. 73

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. John D. Hays K7VE PO Box 1223, Edmonds, WA 98020-1223

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! 73, John

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. 73s de Juan, EA5XQ

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. '73 Eric Scott KC7KLZ PS Even though I have an American Call sign, My current QTH is in Richmond BC. I'm working on getting my Canadian call sign. '73 EES

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.

Hi, everyone, I am Michael. I live in Nanjing, China. Have been license since 1990, active in HF DX/Contesting, Satellite, and EME. Experienced in Linux/BSD and Java/C programming. It's interesting to play around with Raspberry Pi.

Hi everyone. I ordered my RPi from Allied Electronics in June and was told it would "despatch" within 11 weeks. I hope it is sooner than that. Anyway, I envision first trying to set it up to run jnos on linux. Currently, I use Ubuntu 12.04. So far, it appears this forum has some really good experience on board and should serve as a valuable resource. 73 ~ Ken

I am running Raspbian with the latest firmware and software updates as they come along. I have WSPR 3.0.1 compiled and running reliably with full CAT control and internet access. I have tried installing several applications using synaptic package manager (if you don't have it get it "sudo apt-get install synaptic"). The amateur radio section of the package list is quite large and I have tried several of them:- gpredict works very well. fldigi works but cpu is maxed out on all modes except wefax. I can't get good decodes of PSK31 with fldigi using portaudio although they are clearly on the waterfall but decodes work and CPU load seems lower if I install pulseaudio to handle the USB sound card. Cat control via hamlib works fine. WSJT as installed by synaptic or apt-get does not work. I have download the code as recommended by Joe K1JT but get a load of errors during make and it does not run. This may be due to me using gfortran instead of G95 which I don't have. I have installed some other psk31 and QRSS packages such as glfer, gmfsk, gpsk31 and phaseshift but these mostly expect a device at /dev/dsp which is not set up on the Raspberry Pi. It seems that not all amateur radio software that uses the sound device for input handle audio the same way. Some require portaudio, alsa, labjack, or OSS and this becomes a minefield with which I am not very experienced! It is also almost essential to alter /etc/modprobe.d/alsa-base.conf to allow the external USB sound device to be grabbed first. I have yet to find any USB sound card that works perfectly although cheap devices using the CM119 chip seem to be the most reliable. One lesson that I have learned is not to use USB->RS-232 adapters. I tried most variants and all were unreliable (although this has improved with the latest RPi firmware). I finally used the UART /dev/ttyAMA0 which comes out as 3.3V logic levels on the GPIO connector. This is utterly reliable for CAT control or connected to a TNC or GPS via a MAX3232 chip interface. There is a lot of other stuff in the repositories and elsewhere but I have tended to look mostly at low speed data modes using sound input. I'm not sure what is getting most of my attention these days - the raspberry pi or the new puppy but the XYL says it is not her! Dick G4BBH

Hello I have just downloaded the wheezy-raspbian.zip using my Window 7 machine. I unzipped it and copied it to my SD 4 GB card using Win32DiskImager. I was surprise to see the Raspberry Pi load up! My first try! My monitor had a DVI connector, so I had to purchase a DVI to HMDI adapter. I also have connected to my large flat Samsung TV. This is were I would like to keep it. I now want to purchase a WIFI dongle and a wireless keyboard and mouse. I would like advise as to which make and model of dongle, keyboard and mouse that will work with the Raspberry. Is there a list of compatible hardware anywhere? Thank you Don VE3HOL

I loaded it up on my RPI and I plugged in my Microsoft Wireless keyboard. It was no great surprise that it doesn’t play well. This isn’t about that particular problem but it sets the context for the following. I keep getting USB resets with this release. I did not get those with other versions of OS. The system recognizes the devices and labels them Ok but the keyboard randomly repeats typed input until stopped. For those who will suggest USB power, I did plug in a powered USB hub and hung the wireless off it. No difference in behavior. 73, Alan – W6ARH http://mobokits.stormwarning.org/ http://wb6dhw.com/For_Sale.html

According to: http://elinux.org/RPi_VerifiedPeripherals ...the wireless USB Adapter D-Link DWA-131 is compatiblem with the Rasp PI. Here is what the above website says about it: DWA-131 USB ID 07d1:3303,Realtek RTL8192SU, 802.11n Wireless N Nano. Works out of the box on Raspbian "wheezy". Verified with direct USB : no powered USB hub needed. Also verified when Nano used in powered USB hub. Someone had trouble configuring SSID/Passphrase in etc/network/interfaces file. But no problem & very easy to configure using wicd : wicd is a gui interface on LXDE for network configuration. Install it using command-line : apt-get install wicd. Once configured ith wicd to auto-run on boot, no need to turn back to LXDE. Recommended. I install wicd but no sure what to do next. How do I configure it with wicd? Don VE3HOL

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. -Matt KC2O

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 N6WS

Hi Iam Ian M0BXR. Have worked with windows computers for a number of years. For modes like WSPA and QRSS which run continuously the Raspberry Pi should be very useful. Much better too leave on all the time amd no noisy fans in the shack. Should be an opportunity to learn more about Linux and programming and to get some interesting projects working. At the price they are they can be built into dedicated systems. Also interested in hardware projects which interface with the pi.
