Hi all,
Been looking at the diagram again and it looks like L09 is actually just a preselector extender for the 160 and 80m bands. If you look at wafer S1-J (i think it is) this coil is shorted out for all bands except 160 and 80. Its just allowing the preselect coil to cover these bands more easily and improve the position on the dial.
The other thing is, and if anyone is interested, the FT101ZD which has a very similar PA circuit does not have any coil like this in it. I guess when they did the 901 later, they extended the range of the preselect using this coil.
My guess is, there is no real adjustment to do with it, other than make sure 160 and 80 are covered on the preselect dial. I think!
Like i said before, your very fine LCR meter (which it is) may not be able to accurately measure inductance of dust iron RF coils. RF coils should be tested at RF, not audio like 1khz.. Its a different world and my theory in advanced magnetics is limited... Maybe the manual value is even a mistake. Either way, simply short it out and rule it out. Just like the 101 does.
Take care everyone.
Sorry for your loss AF6LJ, i know what its like, like loosing family isnt it.. Had so many pets over the years.. Now these four are a real handful, around 10 months old and a mother cat
