WSPR by K1JT released

WSPR (pronounced "whisper") stands for "Weak Signal Propagation Reporter." This program implements transmitting and receiving for a digital soundcard mode called "MEPT_JT", an acronym for "Manned Experimental Propagation Tests, by K1JT". This is the initial release of a GUI-based version of the program. Screen shot.Click here to download WSPR. Then run the resulting executable to install the program. A full manual for WSPR has not yet been written, but a Quick Start guide is available. Program changes since veraion 0.5 are described in the Changelog. A basic description of the WSPR protocol can be found at .
Please send feedback on WSPR and its use to k1jt at arrl dot net.
WSPR Suggested Frequency Matrix

Note: This table reflects current practice. I recently sent out an alternate proposal for 17m and 10m, but that is not reflected here.
Also, please note that many JT65A operators also run WSPR while on JT65A calling frequencies, particularly 7.076 and 14.076.

I'm amazed, I must say. Seldom do I come across a blog that's
both equally educative and amusing, and let me tell you, you have hit the
nail on the head. The problem is an issue that not enough men and women are speaking intelligently about.

I am very happy I came across this during my search for something relating
to this.

What you wrote was very logical. However, what about this?
suppose you were to write a killer post title? I mean, I
don't wish to tell you how to run your website,
but what if you added a headline that grabbed a person's attention? I mean "WSPR by K1JT released"
is a little plain. You should glance at Yahoo's front page and see how they write
article titles to grab people to open the links. You might try adding a
video or a picture or two to get readers interested about everything've written. In my opinion, it could bring your posts a little livelier.
