What's the CD band there? We have 2 CB bands. The good old 27 MHz, which uses exactly the same specs as the USA and UHF, which has 80 channels (75 available for voice use) from 476.4250 to 477.4125 MHz at 12.5 kHz spacings. Originally, there were 40 channels at 25 kHz spacings, but the specs were upgraded in 2011. UHF CB has been here since CB was legalised in the 1970s. Originally, the authorities wanted to have UHF only, but the sheer popularity of 27 MHz forced them to legalise that band too (which was an amateur band here at the time). 27 MHz was originally 18 channels on a unique bandplan, but the specs were quickly changed to the US 40 channels. Ph> That's amazing to be able to do that on UHF. Yeah, tropo is good fun. :) At home at the time, I used to run a pair of stacked 11 element Yagis, which was a pretty potent antenna system (there are no restrictions on antenna gain here). :) .... An unbiased opinion is always absolutely valueless. === MultiMail/Win v0.51 --- SBBSecho 3.10-Linux * Origin: Freeway BBS Bendigo,Australia freeway.apana.org.au (21:1/109) .
