Fairite 43 mix is very good at HF as long as you use the correct size and 
amount.

Try to contact W3JN at the Athens US Embassy, maybe he can help with getting 
what you need shipped from the USA.

If not I can ask my son with the USAF in Germany, his wife is Greek!

If i use some turns at the end of pll's audio coax cable on a ferrite bead 
#43 it will helps, to reduce R.F interference from linear amplifier or 
antenna to pll
unit? Or i must use ferrite toroid only? I have only #43 material ferrite 
beads.
see my schematic
