update on 23cm Repeaters as of 5th December, 2022

 a recap on 23cm repeater systems centered around Sydney as of  5th December, 2022

Here are the operational 23cm FM Analogue repeaters I can work:

OUTPUT / INPUT    CALL          Location

1273.100 / 1293.100 VK2RTZ  Mt. Sugarloaf  - working,  it idents every hour, requires 91.5Hz ctcss

1273.200 / 1293.200 VK2RWC   Chatswood  - working

1273.400 / 1293.400 VK2RAG  Somersby - working, has beep on the tail

1273.500 / 1293.500 VK2RWI Dural  -  yes, it is working again.

1296.850  VK2RMP FM Simplex analogue parrot repeater at Maddens Plains - working, it idents regularly with a CW message

There is also some wide band or frequency  hopping digital signal that comes up occasionally, can be any time of the day, however, it only runs for approximately 30mins, then disappears,  it seems to come from direction of the city,  I won't call it interference, as it maybe a legitimate user of 23cm, as we are secondary users. It just annoying when you scanning. I see this signal down at 1250 MHz and all way up to 1296MHz, sometimes it will keyup Chatswood rptr and also keyup the Maddens Plains parrot rptr. 

1294.000 FM Simplex, not heard anyone since July 2022.

There are other known 23cm Repeaters, i.e VK2RRR Razorback and  others at Blue Mtns, Walcha, Muswellbrook, Lismore and Jervis bay,  all these have been unfortunately been cancelled, scrapped or never completed.
