Well, after a bit of hair tearing, I have managed to get my WSPR encoder running on the propeller platform.  I am doing some cleanup of the ...

In my previous post , I was thinking out loud about my WSPR encoder for the propeller-based beacon project.  Dave, G4FRE posted a couple of...

I have been pondering why my WSPR encoder routine could be giving me incorrect results.  When I encode my message "KO7M CN87 27" a...

After letting the new power amplifier run on the Propeller WSPR beacon today, I see a much more lively WSPR map: I expect as the sun as...

This morning I finished up my beacon power amp by putting in the low pass filter.  I had a bit of a struggle with that however, as I had no ...

Um...  Ok...  I lied...  It is just plain ugly construction... But, hey...  We are trying to prove a concept, right?  :)  Well, time to...
