LF,
 
Is there a fairly simple interface unit which will enable me to
transmit WSPR signals using my home built MF TX ?
 
My TX has a VCO / FSK facility but no audio inputs.
 
I've had a search of the internet but haven't yet found any suitable circuitry.
All the articles I've viewed so far assume that one has an SSB transceiver...
