for 2.: Discussed to the end if you stay at 441MHz. If you still want to
have it in, just send  a patch and no more info is needed. (Likely Andy
is giving only examples for more difficult cases, sorry.)

for 1.: I would like to be absolutely sure, that we are talking about
the same tuner. I want to have the exact filters on it at least.

3.: That is what Andy noted. Following the Philips datasheet for TOP, it
should be added for negative modulation, positive modulation and FM
accordingly. (2 and 3 are out of discussion)

If you still have some sort of Secam fire and can improve it, we must
know the tuner you are on "exactly". If it is the original Philips,
without any such TOP suggestions over the full range in recent
datasheets (???), I assume you might have them, I would say you can
proceed, if you have shown that you are really still on the same tuner.

Cheers,
Hermann
