QRP Labs...will the wonders never cease?!

Hans G0UPL announced today that he is using new (not yet released to the masses) firmware that allows the QMX+ to emulate one of his first kits - the Ultimate 3S.

The U3S is a many-mode beacon transmitter that offers some amazing functionality, especially given its low price.

It is primarily used as a WSPR transmitter but is also capable of Hellschreiber, Opera, QRSS, all of the JT modes and more; plus automatic band-switching and GPS control of frequency.

I built one about 14 years ago and I still have it today; in fact, it's operating on 20m WSPR as I type.

The QMX+ has become the QSX and now the U3S.
