TX500 is not supporting WSPR or Opera
Opera is a single frequency on/off CW key replacement mode , if it can
send CW or QRSS , then it can send Opera via the com-port keying
facility, as many of the MF/LF stations are so doing.
WSPR on the other hand is FSK based and requires , either audio>Rf
translation or DDS excitation , each has its own uses , the design
requirement / concept of Opera was a 'Data mode' ' To be sent via a
normal CW Tx'

Uwe,
here an Email from Juma from 2/2012 1regarding further developments:
Hello Clemens,
Thanks for your interest in JUMA TX500.
TX500 is not supporting WSPR or Opera. We will consider new transmit modes
in the future.

Uwe,
The Juma 500 is a FB little transmitter, lots of built-in features
(synthesizer, keyer, swr bridge, receive preselector, receive
converter) in a very small package. It is capable of more than 60W
out, I have run it with 15vdc (which is in-spec) and with a 30 ohm or
so antenna impedance you can get 100W out all day and all night with
no complaints.

What do You think about the JUMA TX500 TransmitterI
In my eyes a small Rig with 60 Watt and built in Converter.
By the way, have a look at the filters in use – easy to built an
duplicate
