Looks like ACMA are going ahead with extending the top channels up a few khz. This is to accomodate 80 12.5khz spaced channels. Repeaters will be made to swap to narrow band to. With channels interleaved with the current ones. After 5 years old wide band gear will not be suported. Repeater allocation rules have been relaxed. Anyone know to what exactly? Hope the bashed that 20km rule in the bin. Nice to see some commonscience took place and we didn't get a mixed bag of wide repeaters and narrow simplex channels. What a crock that would be!

Still kicken Kev. Yes most people i would suspect it's just a tick the Narrow box in the software.

You reckon most people are using ham radio's? I heard someone say over the air once that 25% of people already use half channels but I don't believe it. I find 25% of transmissions much more believable as extended conversations occur far more frequently there.

Yeah, when I first heard that, I thought it was incompatible, but I realised narrow transmissions through a wideband repeater would probably be come through to narrow receiver fine.

No it won't as the repeater will RX it as a narrow band and TX it as a wide band with very low audio and it would be RXed by the narrowband radio as low audio and distorted/clipped The QLD Police had this problem when some narrow band radios were installed and used on the wideband repeaters Kev

Technically speaking it will. Narrow in should give you Narrow out too if the repeater is working spot on! You should get the same out as what went in. Obviously in the real world things will not be exact but close. Things like distortion and diferent frequency responses in the gear used to make the repeater can effect this. Commercial comms repeaters regenerate the different CTCSS tones at the tone panel for that customer. Once the RX has picked up the mobile and the tone panel has worked out who it is (or if it's valid) it will be re generated and sent out at the level set by the repeater operator. The voice will be as above. Since CB repeaters aren't CTCSS controlled for acess this isn't a problem. It is an issue for the commercial boys running a mix bag of radios to different customers.

OK, 2010 - not sure if it is accurate, but you asked for a closer date "PJ" <rredbeak@optusnet.com.au> wrote in message news:4c1ddf15$0$17177$afc38c87@news.optusnet.com.au... > someone sais 2011... can anyone give me a closer date please ?? > > Cheers PJ > > > > "Station X" <stationxx@gmail.com> wrote in message > news:6f39dcaf-e9d2-4901-982f-3a0cf52ce758@42g2000prb.googlegroups.com... >> Looks like ACMA are going ahead with extending the top channels up a >> few khz.

If you have a commercial radio and it can do for 12.5KHz steps, like Nike says, just do it ?
