This bandplan, first adopted at the IARU Region 1 Conference in Torremolinos (1990) and revised at the 1996 Tel Aviv conference, is recommended for use in those countries in the European part of Region 1 which allow amateurs to operate in this part of the radio spectrum. In many countries in the African part of Region 1 (see footnotes accompanying the ITU frequency allocation table) the 50 - 54 MHz band is allocated to the Amateur Service on a primary basis, and in some cases, like for instance in South Africa, an adaptation of the Region 2 bandplan is used.
The current revision was adopted in Cavtat (2008).

1. Notes
a. Telegraphy is permitted over the whole band; Telegraphy exclusive between 50.000 - 50.100 MHz.
2. Usage
c. The intercontinental DX calling frequency 50.110 MHz should not be used for calling within the European part of Region 1 at any time.
d. Channelized equipment: On this band the FM channel spacing is 20/10 kHz.
e. For the specification of FM telephony see section 8.2
f. This segment is for simplex use only with no Digital Voice gateways permitted.
Embedded data traffic is allowed along with Digital Voice. DV users should check that
the channel is not in use by other modes

In those countries within the European part of IARU Region 1 where it is allowed to set up FM
repeaters on 50 MHz, the indicated channels are recommended in order to establish a commonality.

In those countries where the National Authorities do not permit repeaters to operate with
output frequencies above 51 MHz, repeater output frequencies may be 500 kHz below the
repeater input frequencies.(Tel Aviv 1996)
