I haven’t played around with WSPR for a while, so this morning while I was revising for my Intermediate Exam I thought I’d leave WSPR running on 20M.  I’m much more comfortable with the Yaesu FT-817ND and LDG Z-817 autotuner now, and understand the differences between long and short button presses, so I am able to keep my SWR ald ALC nice and low.

The only issue I am having is getting the RX noise dB correct.  On the WSPR chat page people have told me it should be as close to 0dB as possible, but the only way I can close is to turn the RX down on my SignaLink USB and when I do that I don’t hear anyone. If I have it around 25, I hear plenty, but the RX Noise bar is red!  Anyway take a look at the propagation map for this morning.

I think the next digital mode I’m going to look at is JT65A.  From the little I have read about this, it seems like another WSPR-like piece of software.
