A number of years ago I designed and made this very simple TX for 10m WSPR based on low cost GQRP Club crystals on 14.060MHz. If you have suitable crystals you could easily duplicate it. There is still plenty of WSPR on 10m. If you want more power just add more PA transistors in parallel! 

On my main website is the circuit (untried as I recall because of my stroke) of the full transceive version.
