[hpsdr] Standalone WSPR beacon

[Phil Harman]

Hi Berndt,

I did solve that issue by reading the date and time from the GPS receiver.
I also built a standalone 2m beacon (VK6RIO) using this technique which I
hope will go in service shortly.

One item that prevents the code from becoming more useful is that the WSPR
data is hard coded into the FPGA. In which case you have to compile the
code using Quartus for every callsign etc.

A better solution would be to add the WSPR data to the code stored in the
EEPROM. We could store the data at a specific address in the EEPROM and
merge it with the FPGA data.

So the steps would be:

1. Modify the FPGA code to read the WSPR data from EEPROM.
2. Write PC code to generate the required WSPR code (already available),
read the .rbf file and merge the files.

Nice little 'weekend' project :)

Thanks to Bill, KD5TFD, for writing the original WSPR FPGA code.
