Special Operation — Auxiliary Stations (Internal Links)

In Japan, the authority restricts the use of an internal wireless* link between repeaters only for the following two cases:
(1) An RX→TX link for a 10-meter repeater, and
(2) A bidirectional link between D-STAR repeaters in the 10GHz or 5GHz band.

The authority consideres them a kind of a repeater, and assigns a call sign from a block which is allocated to 'normal' repeaters.

*: An Internet or wired link is permissible.

  1. 10 Meter Repeaters
  2. In the past, three auxiliary stations relaying signals from a 10m repeater receiver to the repeater transmitter existed as JP8YCW, JP1YEY and JR6YU. But currently, the only one 10-meter repeater JP3YHY chose "WiRES" — a wired IP connection — for the RX-TX link.

  3. Digital Repeaters' RF Gateway — "Assist Station"
  4. Second, another internal linking system called as "Assist Station" appeared in the JARL's D-STAR (Digital Smart Technologies for Amateur Radio) project in 2004.
    Assist stations — i.e. RF gateways — rely signals among repeaters which have both digital and analog capabilities for 23cm and/or 70cm.
    An assist station is directly attached to a repeater by wired, and is connected with the other(s) using a multiplexed digitalized mode on 3cm (10GHz)* split frequencies for a 10Mbps duplex link.

    *: 5cm (5.6GHz) is also permissible if necessary.

    Locations

    Currently, five linking systems — i.e. "Zones" — exist in Tokyo, Ueda, Nagoya, Kyoto and Osaka.



    RF Gateways Locations — Restricted for upto Four Stations (Three Hops)

    Stations' Physical Configurations

    Their physical configurations are as follows:
