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.
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.
These details are as follows:
Up Link (MHz) | RX | Internal Link (MHz) | TX | Down Link (MHz) | QTH | Status |
---|---|---|---|---|---|---|
29.58→ | JP1YEY | —Any frequency between 438.00-439.00 → | JP1YEE | →29.68 | Ogasawara | Abolished: June 1, 1986 - 1991 |
29.52→ | (no call sign) | (—WiRES→) | JP3YHY | →29.62 | Hyogo | Oct. 25, 2008 - |
29.57→ | JR6YU | —1200 band→ | JR6YT | →29.67 | Okinawa | Abolished: Aug. 29, 1990 - |
29.55→ | JP8YCW | —439.00→ | JP8YCV | →29.65 | Hokkaido | Abolished: June 16, 1990 - 2005 |
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.
