Re: Equipment.




Hello Tony,
                "Takk for siste" (thanks for the last time, as the NOG's say).

Great !! re: Itune being able to tune 2 x rigs using 2 x parallel ports.

Being as *THICK* as 2 short planks I never even considered putting both parallel ports  into one PC. GM1SXX is ther "brains" of the team, I'm just the one with the "mouth" who takes the credit.

Actually, two old 386's help warm up the shack in the winter but it  *WILL* be nice to  cut out at least one of the noisy fans ... sounds a bit like a southbound from Charring Cross on the underground.

Thanks Tony.

73 John.   <la2qaa@amsat.org>
