[comp.std.internat] Frequency Synthesizer Tuning Increments

bjorn@alberta.UUCP (01/09/87)

A friend of mine is about to buy a stereo system which he
plans to take with him to Europe when he finishes his studies
here.  He is debating whether or not he should buy a frequency
synthesizing (eg. Quartz Synthesizer) tuner.  I seem to recall
a discussion here a while back about the tuning increments used
on European tuners of this ilk being different from those in
North America.  As far as I can tell the tuners here have the
following characteristics:

	FM:	increments:	0.2 Mhz
		start-off:	0.1 Mhz	(eg. 90.1 Mhz -> 90.3 Mhz)

	AM:	increments:	10 Khz
		start-off	10 Khz (eg. 630 -> 730)

I presume the following:

	2) The increments are tied to the conventions employed
	   in assigning radio station frequencies.

My questions then, are:

	1) Are the increments and start-off points the
	   same in Europe?
	2) If answer to (1) is no: Will a tuner with the
	   above mentioned tuning increments be able to
	   tune in all FM stations in a given area in Europe.
	3) Does it matter? Are there frequency synthesis
	   tuners that will lock in stations more finely
	   than their displays indicate?.  Do most of them?

As an example the frequency of the AM station at the Iceland
Defense Force base in Keflavik, Iceland is 1485 Khz, so even
the AM section of a made for North America tuner may not be
able to receive it optimally, even if you'd have a hard time
hearing the difference B-).
