WSPR Upgrade

Thanks to M1AVV for news of the latest upgrade to the superb WSPR beacon mode software, which can be downloaded from here (15.7Mb.)

Whilst I've only run WSPR 4 for a few minutes thus far, it's immediately clear that it's a big improvement on the WSPR of old.

For starters, received signals are processed and displayed within a couple of seconds, rather than the several tens of seconds it could take the old version if used on older PCs and what now seem like the very anachronistic 'netbook' computers.

The new WSPR also seems to decode pretty much all it hears; sometimes, the old WSPR struggled with signals afflicted by strange propagation effects.

Adjusting the RX noise is cleaner and easier now, and a handy new 'make the next cycle a TX cycle' button avoids having to slide the TX slider to 100% and then back again.

All in all, almost perfect.  It even adopts the existing interface settings, though it did take a couple of tries to get the TX to work properly - for some reason, RTS had changed to VOX.
