The Australian Government recently approved the UHF CB 40 Channel allocation to be “Expanded” to 80 channels.

This was achieved without extra bandwith by interleaving the extra 40 (minus one Ch#80 ) at 12.5Kc spacing between the original 25 kc spaced channels.

The last channel #80 seems to be added on top of the original 40 Channel allocation  at 477.4125.

I have operated on UHF CB since day one, at first with a Phillips which I converted to 88 channnels within 3 days of release just to see if I could.

Goldie loved it as his own as he didnt think it was possible. Sayonara Ham Ticket. Anyway got Sawtron 880 UHF CB Mobile replacement from Greg at the Importers, Imark.

We were both from same country city and I had first chance at Sawtron 200 Base console that plugs into remote head attachment on Sawtron 880 Mobile body.

Has many advanced features of the time and I added a thumb switch controlled digital tone decoder to go with the sender for selcal each way to home from my Phillips 900 in my panel van at the time.

Only has 5 watts from the 880 body but the Audio from the base console electret top mounted microphone is crystal clear and booms out!

Even with only 213 coax and a 6db coaxial colinear mobile antenna most think I am running 25 watts. I wish! When I lived in Northcote on top of the hill with LDF450 and 12 db antenna it kicked ass into Tassie sometimes.
