Great idea for those lucky enough to have more than 1 four wheel drive

Same unit as I have in the troll but not the same bracket. Good little uhf:D

Is yours a suction bracket??? I've never been found of window mounted suction brackets had one on the gps and didn't take long before it wouldn't stick any more.

The gov have had a huge overhaul of the frequencies and have halved the band widths. So more channels per hertz. (think that's right)
With new digital technologies the units are a lot more precise with sending and receiving.. so I'm yet to try a 40 channel and a 80 channel, but it sounds like say channel 20 on the old units is 40 on the new.. so I'm hot sure how its all going to work with emergency channels etc threw the change over period.

And some radios are upgradable. We just had our radios at work done.. probably cheaper to just buy a new one..

G'day Westy,
Close enough... minor thing tho, Channels 41 thru 80 are interlaced into the 'old' 1 thru 40. That means that channels 1 thru 40 are the same on both an old 40 set or a new 80 set. The order by frequency is essentially 1, 41, 2, 42, 3, 43 etc but as the band is 'channelised' the freq's allocated to the channels do not need to be in any order just the same for everyone.

The emergency freq's work fine with either channel plan as there will be a significant period for the emergency repeaters to be upgraded before the interlaced freq's of 44 and 45 either side of the existing channel 5 are released for repeater licence use.

Bottom line is essentially that the difference between 40 and 80 sets when operating on channels 1 thru 40 is bugger all other than maybe the need to up the volume a tad

Mine is the traditional drill bracket but same uhf

I pick up one yesterday from a local shop was 20 bucks more than eBay but I thought what the hell good little unit the aerial is good for 2 km range apparently and if you want to later it can be hard wired in and a bigger aerial attached. I am pretty happy with it all round


Just tap it in just tappy tappy tappy

Sweet as. Good to get some clear data on it.. tbh I haven't read much about it, just talked to others about it.
Cheers

Why does it need to be hard wired? cant you just run a bigger aerial on your main vehicle and just use the small aerial when swapping between vehicles

[93patrol]

I believe you can but you couldn't go too big because of the magnet but you could get a mounted aerial and just leave there
