VHF/UHF FM Repeaters

The club operates a number of repeaters, on 2m and 70cms  as follows:

VK2RBV Sydney City 438.1125 -5.4Mhz FM 91.5
VK2RBV Sydney City 438.1125 -5.4Mhz C4FM
VK2ROT Paddington 147.025 +600 FM 91.5
VK2ROT Paddington 438.575 -5MHz FM, AP25, IRLP (#6250), Echolink (#725953),



VK2RBV Sydney City 438.775 -5Mhz DStar

IRLP-Currently offline due to software issues

IRLP allows hams to talk through their local repeaters to other local or international hams using their repeaters through the Internet connecting via simple DTMF tones. For example, to link to node 2050 in Halifax, Canada, just key up our VK2ROT 70cm Repeater and send DTMF tones representing that node’s number, *8002050. This allows two-way voice communication to Halifax  but of course, you will need to call CQ to see if anyone is around! To disconnect, just key DTMF *73. Check  the detailed usage notes here:

You can also join voice chat rooms called Reflectors. Many repeaters can link through one reflector such as 9050. To disconnect, just key DTMF *73. For hams to contact us, our node number is 6250 and it’s status can be checked on the IRLP status page

General information can be obtained from the official IRLP site.


Echolink enables hams to contact each other through the internet and via repeaters. The facility is available on our VK2ROT 70cm Repeater. It operates in a similar way to IRLP except for node numbers, when calling through our repeater, must be preceded with *3 while the use of DTMF *73 will disconnect both Echolink or IRLP services. For those wishing to call us, our Echolink node is 725953.  Check the detailed usage notes here:

General information and the node status can be obtained from the Echolink site.

If you are planning a visit to Sydney, give us a call on IRLP or Echolink.

Sydney CBD Repeater Stack
VK2RBV DStar and Gateway

Besides the P25 Services also available on VK2ROT at Paddington. Waverley Amateur Radio Society is working with other groups to expand the Digital Radio Services available for testing by the Amateur Community.

C4FM Repeater

The club has installed a 70cm Yaesu C4FM repeater, VK2RBV, this unit is currently co-located with the D-Star in Sydney CBD on 438.1125 MHz with a -5.4MHz offset. The repeater is configured as AUTO-AUTO, in Yaesu speak this means that an FM signal will be repeated as FM and a digital signal will be repeated as digital. It also covers most of the Sydney basin.
