So far Mr B2 your theory seems to be holding valid
I have been scanning the CB frequencies off and on for the last couple of months and am still trying to get my head around what is happening on Channel 7 in particular.
It is like a war zone interspersed with the occasional lull in hostilities
Colourful personalities with handles such as "001", "004", kevin, rocket, shorty etc seem to get the most vocal interjections and carrier-dropping, to the point where the repeater crashed bigtime a few weeks ago
In addition the power on the repeater seems to go up and down .... one wag called it the Blacktown intercom
On one recent evening the Channel 7 ident and repeater even showed up on Channel 1 (476.425Mhz)
It can be entertaining at times but at this rate i can't see it as a going concern longterm.
It is a pity CB in Sydney has become the way it is, as I use to enjoy listening to the conversations, especially late at night on nightshift at work
I even listened to Mr B2 while he was driving his bus late at night and maintaining a commentary
