Ah.

My femon (dvb-utils on my Gutsy Mythbuntu) does not have the -H option.
It's probably too old.

I shall look at the hg sources.

The first script created a nice baseline and comparaison tool for the
before and after masthead amp installation.

A 26-dB masthead amp + associated in-line power supply gave me 20-25%
better signal strength, and most importantly brough all the BER to zero.

I'm happy :o)
