Never mind that nonsense, Tony - I'm still waiting to hear if an FM signal
strength of '55 dBf' as per:
http://www.apah69.dsl.pipex.com/show/Signal.JPG
Is reckoned to be 'good' (or 'good enough')...???
(Certainly sounds OK!!)
Keith:-
If I haven't pressed any wrong tits on my calculator,
55dBf means 55dB above 1 femtowatt, or 10^12 watts
55dB is a power ratio of 3.16 x 10^5
so 55dBf is a power level of 0.316 microwatts.
Assuming a standard 75 ohm antenna, that translates to 4.87 mV, so I'd say
that was a pretty good signal.

What staggers me is the references they give. Do Abbey Road *really* use
stuff like this, and do they know their name is being use by these people?
Glad to see there isn't a single Broadcaster amongst their references.

They probably sent a free one there, and have based their claim on the
fact that it may, just possibly, not have actually been thrown in the
bin.

That tuner uses a common place audio demod chip just to drive the sig
and deviation meters!. They use a totally separate pulse count
discriminator for the audio .. and excellent it is too  )
