Hi all, I just got my TNC-Black and am setting it up and can not get the ax25 working.When I run kissattach command i get this error "tty_speed: tcgetattr: Input/output error"

?

I have my TNC set for UART1 which should be /dev/ttyS0. The command I am using is:

?

root# /usr/local/sbin/kissattach /dev/ttyS0 0

?

Also I the "pitnc_setparams" doesn't work either.

Re: Has anyone used a Raspberry Pi to run Slow Scan Television

 

Hi all. My last attempt didn't seem to post so I'll try again.? I've been trying to get the sstv from www.instructables to install. I get as far as
gcc -lgd -lmagic -o pisstv pisstv.c and it comes back

/usr/bin/ld: /tmp/ccHqMKef.o: undefined reference to symbol 'sin@@GLIBC_2.4'

What am I missing?

AX25 setup help needed for a BBB to support a TNC-Black

 

I was directed to post here for help. I cannot get the AX25 running on either of my BBB using a TNC-Black. I have been to a lot of sites and they just don't help. If some one has done it and can help please email me.

Stan, there is a program called 'xming X Server for Windows' that will allow you accomplish what John mentioned. You can use it with putty to ssh in and grab a x11 session. Here is a link to a pdf that will help you if you choose this route.


As far as your initial question there is some documentation here:

At the bottom of the link you can select the operating system you are trying to connect from and it will go into further detail.

There is also another video output available on your version of the pi with use of a 3.5mm four pole plug to three RCA cable.

Hope this helps and best of luck,

Stan, like Alan I use xrdp also.
XRDP is much easier to setup then VNC but as Alan said make sure you setup SSH so you can use PuTTY or some other terminal program to remotely administer the Pi.

VNC + Audio

 

I am confused!
Should I be able to run a Linux system (RoboLinux) remote with audio from a Win7 computer?

Re: VNC connection problem

 

If you are using linux, you can use ssh -X (pi hostname or IP address ) ?and run the pi's X-Windows session on your linux PC.

The X-Windows runs better on a PC than it does on the pi. ?

I mention this because if you are planning on using VNC on MS-Windows?

Thank you for your very prompt response Alan.

You have given me something to work on. I will have to find the previous posts that you referred to and emulate?a setup with my RPi B+ before passing the info over to my granddaughter.It sounds?like VNC setup is a well trodden path although it doesn't seem to be in the files.

Greetings everyone, I am a new member.

?

I have a problem successfully connecting a VNC (tightvncserver) between a laptop computer and a RPi B.

?

The RPi B and the laptop are my 11 yr old granddaughter's who lives in Cyprus.

?

I have just bought her the B and the problem is that she does not have easy access to a hdmi tv and would prefer to use her laptop with the RPi.

?

We can readily identify the IP addresses but the laptop and RPi don't want to talk to each other. Obviously I must be doing something wrong.

?

Is there surefire way of doing it?

?

I now have a RPi B+ myself and hope to utilise it in amateur related activities.

Re: Raspberry Pi (B) with TNC-Pi not working

 

Have you tried Vox mode on the radio? I read somewhere that it might need to be enabled for certain radios. Maybe that will get things transmitting?


Re: Raspberry Pi (B) with TNC-Pi not working

Gerald Lynn
 

Thanks for the tip on get get_ params. I have not got it working yet. I am copying other stations, but it won't transmit. Xastir says it is but the ptt lite doesnt come on. Frustrating!

You are getting further than I am. Still haven't gotten the pitnc_getparams to work right. I do have it setup in Xastir however, and it will let me start the interface, configured as serial device, as you have above.?


Did you see this, about later model boards, needing a 1 0 to get pitnc_getparams to work right?



I wish Xastir had better Digipeating capability, since that is what I really need. We do public service events in rural areas, and while I can setup an Igate for efficient traffic passing, I really need to be able to Digipeat those same packets back a fair distance to reach the Igate. There are not a lot of Igates in rural areas.

Hopefully I can find a Digipeater software that works well with TNC-Pi, as I would rather do it this way, as opposed to a USB audio soundcard.

Hi Jim,

I'm sure you're aware of the WSPR Forum, otherwise it seems this is the place.


I just installed WSPRRY on a model B. I connected it through a
commercially-made 20m band pass filter to a large loop antenna.

I have not seen any reception reports even after transmitting for
several hours on 14097000. I decided to monitor it on my HF receiver,
and can clearly hear when the transmission start and stop.
It sounds like you've got what it takes - but I've found the antenna to be all-important with R-Pi-level power (40mW). I don't know if you mean you're using a magnetic loop or a larger loop that is tuned to 20 meters, but I suspect either will work if resonated and fed with low-loss feedline. I have a mag loop halfway completed that I was going to try on WSPR but can't speak from personal experience (yet). .

But having put my WsprryPi beacon bask on the air again just yesterday I can report that I am getting between 2 and 6 spots from US reporters every transmission, using a 3 element SteppIR at 55 ft. In the past when I used my HyTower vertical antenna, the spot rate would be significantly lower but it was still heard. If you still get no spots, I'd try a simple 20 meter dipole, even if it's not very high, as this would provide a basis for comparison.

I expected to hear some varying tone, perhaps like those I hear when I
operate WSJT. What my untrained ear hears sounds more like a constant
carrier, with the tone not seeming to change. Does this mean
something is wrong?
Probably not, the frequency shifts are so small (around 1.5 Hz) that it's very difficult to detect them by ear.


I tried 2 different packages. The screen displays are different, but
the results seem to be the same.
"
and "git clone

Suggestions appreciated.
I use the JamesP6000 verision exclusively due to the brilliant self-calibration feature he created. It has eliminated the #1 source of frustration from my earlier attempts and I recommend it, otherwise you'll have to come up with the required frequency correction factor using one of the other methods described. WSPR requires a high degree of frequency accuracy and real time synchronization, and this version can do both automatically from the command line. I also like the "-o" or Offset feature, which changes your transmit frequency slightly to increase the odds of being heard.

It's amazing to know that an I/O pin on a computer can generate a signal that can be heard all around the world. Keep trying and I'll look for your call on the WSPR map soon!
