Here is an idea for a self-contained low cost transceiver.
Ingredients:
1. Raspberry Pi $35
2. 3.5in LCD display with composite input $15 (available for car back-up cameras)
3. Peaberry SDR from AE9RB $130 (shipping included)
4. Wireless KB/mouse $15 (available from Fry's/Walmart locally)
5. 12V to micro-USB cable to power RPi $5 . There are also 12V/5V power supplies available.

So far $200 + shipping. No USB sound card is necessary, because Peaberry has ADC for RX I/Q that is routed to USB and handles the rest (TX I/Q, mic) onboard.

KM5H case for the Peaberry ($25) and Adafruit case for the Raspberry ($15) bring that to $240 plus some shipping. It would be nice to have a case that holds everything together: display, Peaberry and Raspberry.

The missing piece (other than the single case) is the SDR software to demodulate the RX I/Q, to display the waterfall, to control the frequency/PTT, and to generate/demodulate digital modes. It has to work on a low-res display. Connecting an HDMI display defeats the low cost and the self-contained goals, but may be an option.

John,

It looks like you are missing cmake - try sudo apt-get install cmake

I also had to install libusb - sudo apt-get install libusb-1.0

I had to cd .. before running make.

It all compled and installed - I don't have a dongle to test it with,

I have used this script with Ubuntu successfully but not with Wheezy latest
(updated today).



Got source with

git clone git://git.osmocom.org/rtl-sdr.git
OK (after installing Git)

cd rtl-sdr/ ok
mkdir build ok
cd build ok
cmake ../ Fails cmake command not found
make
sudo make install
sudo ldconfig

Thanks C my forte, Linux still learning.

All links work fine and the project looks great. Looking forward to a final outcome and the possibilities this brings.

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
. 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


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.

Good evening,

I've been wanting one of these for some time, but the idea of waiting who knows how long to get one when ordering from the normal sources wasn't my idea of fun. Last night I decided to bid on several that I saw on eBay; I won one auction today and am waiting to see how the other one goes. Will enjoy having one (or more) of these tiny wonders.
