Hi Pete,

an older version of WSPR was able to generate the data. I don't know if it is
still available but there is an alternative. You can use the following program
from K1JT to generate the WSPR symbols:

http://physics.princeton.edu/pulsar/K1JT/WSPRcode.exe

Download the program, open a command prompt window, go to the directory
containing wsprcode.exe and type:

wsprcode "SM6LKM JO67 20" > symbols.txt

Press enter.

The output from wsprcode.exe will be saved in symbols.txt. Open this file and
look at the last table labeled "Channel symbols". This is the data you need -
the 162 WSPR symbols. This table should be identical to my example in the file
mjb002ug.pdf (I haven't checked). If it looks OK, just replace callsign, locator
and power with your own numbers.

Write a new text file similar to my "Example download file" on page 6 in
mjb002ug.pdf and replace my message (the table under command character T) with
your own 162 digit message from symbols.txt.

The ugly "HyperTerminal" in window$ can be used to download the file into the
PIC. Set it to 9600 baud, 8 data bits, no parity, 1 stop bit, no handshaking and
use "Send text file" to download the data. Please note that you must start the
download within 5 seconds after PIC reset / power-on (while the green LED is
still lit).

If you don't have a 5V <-> RS232 converter to put between the PC and the PIC,
you can try a one-way download by connecting the PC's TX line to the GPS input
on the PIC board (the transistor will do the necessary logic inversion).
However, you will get no confirmation of download success..
