My LF Upconverter is a narrow band one with about 400Hz of useable spectrum http://www.g4jnt.com/ThirdMethodUpconverter.pdf   , so if WSPR-15 were placed at, say, 137604Hz at the lower end of its proper allocation,  with WOLF at  137630Hz it could be persuaded perhaps.   Will ponder and think about the best way of mixing them.  And, more to the point, generating them simultaneously.

But....

Priority first really ought to go to undoing the bodges and short cuts on the old Linear LF PA that I did back in the dark ages.   Like feeding LM317 regulators with 50V !   But, to be fair, the old circuit diagram found in the archives here did label Vdd  "28 - 40V" so was probably aware of that issue back then.  

I also noticed that when running it the other night, it rained during the last couple of hours which detunes the antenna slightly.   The resulting reactance caused the PA DC current to increase from 9A to ~13A.  It survived happily enough, but I have no current limiting or automatic overload protection.

Can you transmit DSB? 
LSB = WOLF-whatever-speed 
USB = WSPR-15
That would be interesting!
