What happened to 27 MHz SSB?

I had a look at Prestigecom.net.au for some scanners and cordless phones, and see that although 27MHz AM CB radios are still made, there is no sign of SSB units. Doesn't anybody use these anymore?

Yeah, they're still made. We're at the bottom of the 11 year solar cycle right now so the conditions are very poor. No skip means no interest.
27Mhz AM is used like most UHF radios these days - car to car chat in convoys

all the tards moved from 27Mghz to UHF a few years ago, HOPEFULLY they will all move back there and stay some time soon...

As someone said; we are at the bottom of the cycle, in about 5 or so years we will be hitting the peak and be picking up distant skip stations. This will coax more people into getting back on the air
LSB is still used regulary by radio clubs that are set up in perth. 27 megz is not dead, still relitivly active!

Yes, AM-Amplitude Modulation, FM-Frequency Modulation or at least it used to be
An example
When i used to have a CB in the metro area many years ago....if conditions were good you could talk to the North and South West WA, O/S to Indonesia, Bali etc.
On my brother in laws farm at Beverley , again when conditions were good, early in the morning you could recieve AM radio stations from Melbourne for at least a couple of hours.
When using the UHF on the farm it worked best by "line of sight" and limited to about a 20km radius from base at the farmhouse.
