Hi Philip

I do not have a raspberry (yet)... but I plan to order one for exactly that
(remote sdr on the raspi acting as i/q server) ... may I ask you some
questions if I have my raspi and have trouble with the setup ?!?

Hi folks, thanks for having me...

Names Philip (G4JVF), ex TV service engineer, wrong side of 65, not the
sharpest knife in the drawer nowadays and to cap it all, a total noob with
Linux.

Anyhoo, I like tinkering with QRP beacons on WSPR and QRSS so I had
thoughts of maybe getting a Raspberry Pi to somehow integrate with all
this.
Last night, following instructions on the HamRadioScience site, I got my
Pi to serve via TCP, data from an RTL dongle to SDR# on my PC.
Works very nicely...

Holy grail to me would be to get something like ARGO running on a Pi for
low power usage QRSS grabber sessions but maybe that's not possible....I
don't know..

OK, off to read through all the posts and files on here...

Regards
Philip G4JVF

I agree these will sell fast, even as a "Kit" especially when word gets out to the general Ham community.

Looks Great!

No, I was having a problem that looked like noise on the board, so added an extra reservoir capacitor. The problem turned out to be software, but I left the cap in place.

I'm hoping to get someone to make and distribute the boards, either complete or as kits, but if that falls through I will as a minimum supply the PCB,s

Nice job, they look great, just one question, I notice that the lower board has a capacitor in the R6, with what looks like two wires leading away from it.
Is this part of stacking the boards for some special confirguration?
Again, nice layout.
Are you going to selling these units?

Hi folk,

The production boards have now arrived, and I've built a couple of them,
Here are some photos of a pi with two TNCs attached.

As I mentioned in a post earlier today, the RFM22 prototypes are
working, and I hope to have the production boards in 2-3 weeks.

Hi,

For those new to the group, I have been working on a TNC for use with
the pI that is the same size as the pi and plugs into the expansion
header. The prototype was a TNC-X, with a 26 way header superglued to
board. There is a photo of it on the home page of this group.

I now have two TNC's running, and can connect between them. See photo at
https://dl.dropbox.com/u/31910649/IMGP0573.png. This show the prototype
- the production boards will have a DB9 instead of the Mini-DIN radio
connector. A batch of production boards has been ordered, and should be
here in 2-3 weeks.

I've also built a couple of units using the RMF22B 100 mW 434 Mhz
tranceiver model. They both transmit - I now need to get the receive
side working. There is a photo at
https://dl.dropbox.com/u/31910649/IMGP0575.png

I looked at the higher powered (500 mw) RMF12BP, and ordered a couple
for experiments. But when I looked into the module in more detail I
found it was not compatible with the RFM22B, and is less flexible and
more difficult to program. I've since found the RFM23BP, which is a 1
watt unit that is compatible with the RFM22B, so I've ordered a
couple of them for testing, and designed a board that will take either
the 22B or the 23BP. Although it is primarily indended for use with the
PI, it will also have an async port, so it can be used as a standalone
KISS TNC/Radio.

Hi Philip there is no version of Argo that runs under Linux, though it does run with WINE I think this might be too much for the raspi. There was a recent query about a Linux waterfall program that you may find in the archive at the web site.

Nice photos and good job on this project. I would be interested in obtaining a PCB if you make them available. Can you share some details of what software you used to generate the graphics for the boards? I just received my RPi and have it running. Will load up jnos later today perhaps to see how that works out. The TNC would be a nice addition.
Thanks. Ken

I wonder if the RFM23BP could be hooked to an Ardrino with Ethernet
shield that's readily available from Radio Shack here in the US. That
might be an even quicker and cheaper path to get on high speed UHF .

Hi Steve,

I have a couple of prototype boards using the RFM22 modules communicating
across the room with a bit of wire hooked to the module, and have designed a
board for a proper version with an SMA connector so I can try them with real

take the higher power (1 watt) version, the RFM23BP.

Nice job, they look great, just one question, I notice that the lower board has a capacitor in the R6, with what looks like two wires leading away from it. 
Is this part of stacking the boards for some special confirguration?
Again, nice layout.
Are you going to selling these units?

- the production boards will have a DB9 instead of the Mini-DIN radio
connector. A batch of production boards has been ordered, and should be
here in 2-3 weeks.

I looked at the higher powered (500 mw) RMF12BP, and ordered a couple
for experiments. But when I looked into the module in more detail I
found it was not compatible with the RFM22B, and is less flexible and
more difficult to program. I've since found the RFM23BP, which is a 1
watt unit that is compatible with the RFM22B, so I've ordered a
couple of them for testing, and designed a board that will take either
the 22B or the 23BP. Although it is primarily indended for use with the
PI, it will also have an async port, so it can be used as a standalone
KISS TNC/Radio.

Hi folk,
 
The production boards have now arrived, and I've built a couple of them,
Here are some photos of a pi with two TNCs attached.

working, and I hope to have the production boards in 2-3 weeks.

Hi,
 
For those new to the group, I have been working on a TNC for use with
the pI that is the same size as the pi and plugs into the expansion
header. The prototype was a TNC-X, with a 26 way header superglued to
board. There is a photo of it on the home page of this group.
 
I now have two TNC's running, and can connect between them. See photo at
https://dl.dropbox.com/u/31910649/IMGP0573.png. This show the prototype

Hi folks, thanks for having me...

Names Philip (G4JVF), ex TV service engineer, wrong side of 65, not the sharpest knife in the drawer nowadays and to cap it all, a total noob with Linux.

Anyhoo, I like tinkering with QRP beacons on WSPR and QRSS so I had thoughts of maybe getting a Raspberry Pi to somehow integrate with all this.
Last night, following instructions on the HamRadioScience site, I got my Pi to serve via TCP, data from an RTL dongle to SDR# on my PC.
Works very nicely...

Holy grail to me would be to get something like ARGO running on a Pi for low power usage QRSS grabber sessions but maybe that's not possible....I don't know..

OK, off to read through all the posts and files on here...

Regards
Philip G4JVF

Hi Steve,
 
I have a couple of prototype boards using the RFM22 modules communicating across the room with a bit of wire hooked to the module, and have designed a board for a proper version with an SMA connector so I can try them with real antennas. I should get the boards in a couple of weeks, and they will also take the higher power (1 watt) version, the RFM23BP.

John

John,

Have you made much headway with the RFM modules?

This is of interest to me.

We are using cheap usb audio fobs and the soundmodem software.

Hello

I have very little experience in posting.
I am new to linux, but I did see a small problem with all the digital modes. The sound card chews up most of the usable CPU on the PI.

1) Is there a digital program that will work without the shell? Dose the sound card need the shell?
2) Would there be a programmer that would build a miniature or competition digital program for the RaspberryPI?

Re: JNOS

Rick
 

Thanks, John.  I tried to follow the instructions, but received a message that the binary would not run.  Obviously I didn't pay attention to something.   I'm sort of a nubie at this Linux stuff.  Will go at again.

Has anyone implemented JNOS on the PI ? I've tried without success, but then I'm more of a Linux "appliance operator." Have managed to get simple programs like minicom to work, but nothing that is what one may consider outside of the box.

Additional option to VNC (for LAN type connections)

 

The base Raspberry Pi image have X11 --- Linux desktops have X11, MacOS has it (or you can do a quick install of Quartz X11 (http://xquartz.macosforge.org/landing/)  and Windows use something like http://www.straightrunning.com/XmingNotes/
