I'm discussing with the maker of the TNC-X the possibility of him making and selling the boards. If that doesn't come off, I'll at least make the PCB and software availabale, so you can build your own. 73, John --- In Raspberry_Pi_4-Ham_RADIO@..., ve2hom Pascal <ve2hom@...> wrote:

Re: PI TNC - progress report.
开云体育I wasn't really thinking of direct user access. More a well
sited dual (or more) port node, with?normal?user acess port(s), and a
link back to a base site, using directional antennas if necessary I'd expect a
range of several miles - I've seen reports of these things being used in high
altitude baloons, implying a line of sight range of several miles.with wire
antennas.

I hadn't come across that one. I'll see if a board?which
could be fitted with?either is possible.

It alive!
My Raspberry PI arrived in today's mail. Hooked up a 5V;2A brick, a SDHC with Wheezy, and a USB to 2XPS2 with PS2 Keyboard and PS2 mouse. Once I actually connected the HDMI cable, worked as designed on my 23" monitor. Won't be able to play any more until Sunday. We are leaving for the Spokane Hamfest tomorrow.

PI TNC - progress report.
开云体育Hi,
?
For
those fairly 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've
now received the first PCB's, and built a couple. There are photos at ??and
.
The TNC is largely based on the TNC-X, but I've replaced the serial port with an
i2c connection, so more than one can be connected to the PI. The current board
has?a mini-DIN? radio connector, but I find mini-DIN plugs very
difficult to wire, and the connector is just too high to stack properly, so the
final version will probably have a DB9. I've written a linux driver that takes
the i2c data stream, and converts to a pty that can be used with the normal
linux ax.25 kissattach program. All this seems to be
working.
?
I've a
couple of developments in the pipeline. One is to replace the MX 614 modem,
hopefully with a PIC based solution. Although the 614 works very well, it is
relatively exensive, and only works at 1200 baud. I hope to be able to run at
300 for HF use. I've also bought a couple of RFM22B modules. These are
tiny 100 mW 434MHz data tranceivers - see .
I plan to do a version of the TNC using this module.
?
A
version using the FX 489 modem for 9600 baud links is planned, nut I haven't
started work on that yet.
?

wifo support
开云体育I
found this on the pi site today. I haven't tried
it, but am running a RTL8188 CUS based dongle, installed
manually.
?
WiFi is now supported out of the box If your WiFi driver is supported by the default linux tree, or is based on the popular RTL8188CUS chipset, then WiFi should work out of the box. Boot the image with the WiFi dongle plugged in (a powered hub is recommended). Run startx and select “WiFi Config”. You can scan for wireless networks and enter your wireless password and connect from the GUI. No need to install additional packages or scripts. See .
? The post is mainly about performance
improvements.?

Moderation Turned on
Jerome K
This site membership sure has taken off. It is surely good to see so many Ham Interested in using their Pi for Ham Radio..
I am most interested in being a Responsible Group Owner!!!! I have turned on Moderation for all member posts. No offense to anyone. I just want better control over these types of unintentional and all intentional spammer posts.. I get notficiations on my CellPhone, I can quickly reply too.. So there should not be a long delay between your writing a post and it apearing here.. Unless its while I am sleeping... Thus my request below for moderators.. Many Thanks.. I am open to sugestions that others may have tried.. :) I know other groups have went dead due to spam and I just want to nip it before it can gain control of our group. I know being hacked can happen to anyone!! It has happened to me before.!!! Would like to get a volunteer moderator or two on board.. if any one is interested... 73 Jerry N9LYA |
