Selecting the standard

With this softkey, the following standards can be selected: B/G, D/K, I, L, M, M - jap (Japan)

and N. See also audio carrier table.

Audio carrier table for IF reception

The given audio carrier frequencies are based on the respective video-audio carrier spacing.

The video carrier frequency is 38.9 MHz without the return path option for each standard and can not be changed. With equipped return path option, the video carrier frequencies* are freely selectable.

Standard	Video carrier fre-			Audio carrier1	Audio carrier2	Stereo	NICAM
	quency *			(sc1)	(sc2)	(sc1+sc2)	(nicam)
	in IF position
B/G	38.9	MHz		-5.50 MHz	-5.74 MHz	sc1: -5.50 MHz	-5.85 MHz
						sc2: -5.74 MHz
L	32.7	MHz, (38.9 MHz,		+6.50 MHz AM			+5.85 MHz
	39.2	MHz)		(-6.50 MHz)			(-5.85 MHz)

	38.9	MHz				sc2: -6.26 MHz
I	38.9	MHz, 39.5MHz		-6.00 MHz			-6.552 MHz
M	45.75		MHz	-4.50 MHz	-4.72 MHz	sc1: -4.50 MHz
						sc2: -4.72 MHz
M (Japan)	45.75		MHz, 58.75 MHz	-4.50 MHz
N	45.75		MHz	-4.50 MHz

The display in the third field is dependent on the previously selected FS standard.

By pressing the third softkey, the following audio transmissions can be chosen:

￿￿Audio carrier 1 (sc1)

￿￿Audio carrier 2 (sc2)

￿￿Stereo (sc1 + sc2)

￿￿NICAM (nicam)

Level-dependent acoustic signal

In the function, „level beep,“ a acoustic signal is generated, whose pitch is propor- tional to the received signal level. With this signal, it is possible to optimally align the receiving antenna to a transmitter.
