Do you need a linear with your 706 Mal?   I run WSPR on my 706mk2G barefoot, about 20 watts out the back withclearly only a few milliwatts radiated due to the inefficient vertical here at G7NKS. (7m/30m inv L, with marginal earthing)

 

I still get reports out to 1200km plus and at SNRs not dissimilar to yours

 

My record was Lubos @ some 1600km about 3 years ago!

 

The 706 series are great radios for 475kc wspr

Looks like 17 dB QRO. What have you done? A simple class A amp stage (2N3053 et. al.) behind the IC706 ?
