I was trying to finish the hf radio before the birth but could only finish the balanced modulator and the 9Mhz filter preamp. To do are: the output mixer and the HF PA.

Crystal filter preamp (not yet finished in this photo):

The crystal filter part is not yet tested....use at your own risk...as allways!
