WSPR-X v0.3 r3058

Today I downloaded the latest WSPR software onto the new Win 8.1 PC. At first I could not understand why it refused to TX. Doh! Then I remembered to input VOX, the callsign, grid and audio interface details! All now seems to be working but no Es spots  yet.

An advantage of the later software is the waterfall is in real time (it moves DURING the 2 minute time slot so activity is instantly visible rather than having to wait 2 minutes to see. It also supports the slower, but even more sensitive, 15 minute version WSPR-15 as long as the TX stability is good enough. I tried this on LF before but my LO drift was too poor (old PC and old QTH).

I shall stick with this latest version today to see how it performs. I expect the RX sensitivity is unchanged unless it uses improved algorithms for decoding.

    I like wsprx but it is a dead end experimental branch. The latest version is WSPR4. https://groups.yahoo.com/neo/groups/wsjtgroup/conversations/messages/12797
    But neither works cleanly with DAX audio from the Flex-6300! And I can't bring myself to use wires at the moment.

    Thanks for your report.

    Nobody is presently working on WSPR-X. It was developed as an
    experimental offshoot of WSPR, while I was exploring some different
    programming techniques and tools.

    As it see it, the only good motivation for using WSPR-X right now is
    that it offers an extra-slow mode, WSPR-15. As far as I'm aware, there
    is little or no use of WSPR-15, on any band. (Perhaps I am wrong?)

    Is there some reason why WSPR 2.12 does not do what you want?

    At present the active development branch is WSPR 4.0. Quite a few
    people are using this version, having compiled it for themselves.

    Thanks Bob. Sounds like I should go back to the standard version then.
