Hi, I am Andy G0SFJ, have a Pi - computing isn't really my line, wasn't too impressed by the Pi really, and am now looking at using it for ham radio applications only:

* tnc / aprs
*cw keyer
*gpredict (could not load it!)
* sound card and then some modulation/demod.


I think it is underpowered and I found the Composite video unreadable on a small tv set when I was messing around with Python, so am now going to use DVI.

BTW there are free Python courses at Coursera and elsewhere.

Also I hope to use a wireless access point from D-Link.

I am afraid I get lost with Lunix-speak and I hope towards an easy step-by-step soluton to installing these applications.

I have also just bought an rs232 interface off ebay (For the tnc) and understand that the vendor is interested in a top-ten of ham radio pcb add-ons.

All in all I don't think I'll be contributing much, but reading and hopefully learning...and asking for help sometimes!

Re: No help? Wireless D-LINK DWA-131

 

I'm working on the same issue have you contacted D-Link support yet? I installed wicd which is a network manager but it still won't connect I have a few more things to try but if that dosen't work I will be contacting there support center.

I tried both ways. ?Seemed to work better when I plugged it in direct.

Pascal,

The PI GPIO pins operate at 3.3 volts, and the PI is likely to be damaged by applying 5 volts from a normal TTL port. You will need a level converter on the TNC to PI lead. I used a simple resistor divider. Most TTL inputs are happy with the lower voltage from the PI.
Normally the PI linux kernel allocates the serial port as a console. You need to disable this to use it for packet.
I've used the linux ax.25 and netrom code, and the linux node. I haven't tried jnos.

Hello all,
I have a raspberry pi and I want to use it for making a packet radio server. I have think to use jnos2 and I want to connect it with my mfj-1270c tnc. This one have a ttl port on the back, can I connect it directly to the GPIO port of the raspberry pi?

Other question, if I try to use a usb to serial adaptor when I attach the port an arror says "protocol error", don't know if it's because jnos don't like usb serial port. Any clue?

The standard rasbian distribution now includes the ax.25 and netrom modules. You no longer need a special kernel. Yesterday I created a new image from , ran apt-get update and apt-get upgrade, and the new Kernal (3.2.27) had all the packet modules.

Steve here,

Use to run an AX25 mailbox sometime ago for many years (GB7RUG), and I might bring this back to online status, access via just the internet for starters, if I could run this all on a PI? So really I am appealing to Paula PZT and John BPQ to write some stuff for the PI to support the application. I would also like the software to be user friendly, not hours of trawling through to make it all work! Yes, I am getting a bit older these days and don't think as quick as I did when we ran these FBB based systems 15 years or so ago.

Have not invested in any units yet, as I am a bit confused what main version of Linux is going to be the main supported one for Amateur Radio operation etc? I guess thought seeing that CPC/Farnell now have stock I will be buying a couple of units to play with during this Winter.

I also have interest in using the PI with WSPR and PSK31, and driving a few rigs like the FT2000 etc, so plenty for folk to go at and get it over onto the PI system.

Hi John,

I am using the Debian wheezy image and found the screen to small



This shows settings for the configuration file
I plugged my card into windows machine and edited with programmer's file editor which recognise linux end of line unlike notepad.

Select a lower resolution for larger text and try different settings to get a full screen.

If you want more on this I'll post my file so you can see the changes I made. I assume these settings are valid for various versions of the operating system not just debian.

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.

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?

Hi Paula,



About a month ago I ordered one from Farnell, and despite being quoted 6 weeks it arrived in two days. This may have been a fluke, but the waiting list seems to be disappearing..



If your ax.25 code (like mine) is largely in assembler, then porting to the pi won't be easy, but C shouldn't present too many problems. But linux already has ax.25 and Netrom stacks, so you can take the higher level stuff, and hook it into the existing stacks.

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]
