WSPR TX setup tools ?

Does anyone know of any tx setup tools ?

I have a TX kit here which generates the tones, but trying to setup the desired FSK shift
and seeing if the data is being sent correctly is very difficult.

At the end of the day, attempting to see if homebrew equipment is sending the right tomes
relies upon making a transmission and relying upon the WSPR software to see if a decode has been
possible.

Very long and tedious !

It would be so much nicer if it was possible to just send some test data without the hassle
of waiting for the correct time to transmit, sending 2 mins of data only to find something is not working.

Not like testing other modes like rtty or similar where you can test and decode the data in real time
until you know something is working.

Ideas anyone ?
