It is all ready to be installed and last night I did some tests which showed that it will tune from 21 MHz [...] During a week of very changeable weather in Wales I managed a couple of /P sessions. Setting up in an NT car park right on the coast produced some very good results. Tuning around the SSB section of 20m produced BH7PFH,VU2DK,VK4TUX,VK2IR,W6CCP,W8XH and on CW W7VV who I think was in QSO with [...] I have completed the Smallwonder SW+ 20,it is now in a diecast box and just needs the controls labelling.
