[wsjt-devel] Low cost WSJT transceiver

[Edson W. R. P. <ewp...@gm...>]

Hello Joe and everyone,

For the last few weeks I have been usning WSJT-X with SDRSharp and an
RTL-SDR dongle (using the R820T chip with the new librtlsdr) on 21, 24, and
28 MHz. The performance is quite respectable. I am now working on designing
a simple 5 Watts companion transmitter for JT65 and JT9 using a low cost
DDS (AD9850) and an Arduino microcontroller. I intend to publish the
project and source code.

I would like insert some code on WSJT-X to interface it with a software
that will drive the DDS. For this I am thinking of writing the TX symbols
to a file and have the file monitored. When a change to the file is
detected the driver software reads the symbols and activate the TX.

Do you think it would it be of interest to have the changes committed to
WSJT-X repository? The only addition will be the creation and update of one
file when the TX is activated. No other changes will be necessary.

73, Edson PY2SDR
