Mosfets, with a clean LO and H-MODE first RF Mixer and Roofing filters at 9MHz (the basic project is by G3SBI, G3OGQ,G8KBB in RADCOM).   Antenna changes in sept 2008: 2 different stepper motor antennas SteppIR (USA) 2 element with 40-30m "trombone element" 40m to 6m  and  Ultrabeam (Italy) 3 el. beam 20m - to 6m.  Unfortunately the back moulding inside the trombone motor in the STEPPIR has broken and I had to take the 2 element Steppir down and substituted with only a 30meters aluminum rotary dipole  MB1 30m. by MOMO Antennas.
