Sorry everyone, a serious question! Well to me anyway.

I have been fortunate enough to receive from Santa a UHF radio. It has been fitted and is working perfectly as far as I can tell. Now after reading the instruction book. I know something we don't do until we have to I was looking at the channel scanning. There are two choices, Open scan and Group scan. I realise that as a rule caravans are on channel 18 and trucks on channel 40 except the East Coast where the trucks are on channel 29, for reasons best known to them. My query is which is best? Open scan or group scan and for what reasons? Please keep the replies, if any in a simple language too much techno talk gives me a headache!!!!!!! Thanks.

Terro

Happy New Year.

Quite simply put Sir Terro..................Open scan means you scan all the channels and group scan means you scan the group of channels that you are interested in only. I always have it on open scan when we are away. I don'y use scan around the city................too many F/wits on the air. Is that simple enough for you??? :)

However.......if you were to turn the attenuator 180 degrees and line it up with the modulator then the scan driperlator will work inversed which would cause the duo do-grinder to overheat.....thus increasing the chances of phase lock loop to break down. So take care to keep the two parallel. .......alright mate??

Thanks Mr Duck. I knew I could rely on you to give me the most important details. Fortunately I have my alfoil Moose ears on and the headache has been negated. My attenuator has been attended to and the modulator that came with the set is very modern!! As for the driperlator I have run out of coffee to fuel it. Also with my set I received a free discombustulator which is able to be attached to the froozerhooter for better sound effects. This negates the 180 degree turn on the aforesaid attenuator allowing it to do its task of translate the signals via the scrimwasher. Do you think I have got the hang of this thing yet?

Yep, tried it out around here the other day. The airwaves were a certain colour!!!! Is that the colour of F/Wits?........... At least I found out it receives but haven't tried broadcasting yet.......... I don't have a broad that I can cast!!!! What channels in your thoughts,(with or without alfoil beanie) do you suggest?

Terro.

For once the duck is right open scan picks up every F Wit for miles. better off putting it on the channel you want to monitor and keep it there.

Disco Duck said
06:28 PM Dec 30, 2009

Mate as I said...............when I go away....I scan them all.............don't want to miss out on anything!! So I open scan on the road and around the city...I don't even turn it on unless I absolutely have to!! You'll find once the novelty wears off then you'll be the same!! There are just too many morons on the air!! The language ...as you said....is very nice!!

Disco Duck said
06:33 PM Dec 30, 2009

I am amazed that you recieved the free discombustulator with a UHF. They are normally used with VHF radios only. I guess it is something they had to try because they had so much trouble with the scrombleone. Hope it has fixed the problem......otherwise you could take out the Brinklevalve. Other than that.......yep............I reckon you just about got the hang of it. Ibbo and DaveO would have more of an idea than me though. I don't know much about them!!

We keep ours on channel 40 on the open road...thats where the truckies can be heard warning of problems ahead or whatever . Hadnt heard that they use channel 29? maybe we are out of date, but they were using ch 40 on the South Coast NSW last month.. If anybody calls up to speak to us individually we both switch to a different channel.

A word of warning.... there are lotsa f/wits out there, and theres lotsa stuff on the airwaves you wouldnt want your children to hear. Similarly if you want to have a strongly worded private chat with anybody, remember theres lotsa people listening.

It can be very entertaining!!! biggrin

Terro said
06:58 PM Dec 30, 2009

Yeah, the discombustulator has been upgraded especially for UHF. They were experimenting with a Mk 3 discombooberotor but found the straps were too tight.

Just been out to have another look and I've found the fearnshuller has been disabled and that has allowed the scromblebone to flex and pick up the resonance that the brinklevalve was missing. That in turn takes away the poppetfry caused by the delay in the sploden sprocket. Also the microphone that came with the set is right handed. No good for me!!!!!

I have never in all my 22 years of existance heard so much dribble, the man asks a decent reasonable question and gets flambayed with utter rubbish I'm so sorry Terro, I will endevour to correct this craziness, you asked what is the difference between "group scan" and "open scan" open scan is when you are out in the wilds in the "open" nothing around you and very few things to interfere with your signal, when you choose "open" just quickly jump out of your vehicle and place your index finger on the antenny, you will feel it go up slightly, straining itself in an effort to gain a signal for you! it will find even the weakest of signals, some have been known to be recieved at up to 40 feet away! now group scan is when you are about to have a yak with 3 or more people, like a "conference" call, you can sync your handpieces together and have a "group" talk dont try to use this setup out in the wilds though as the aerial actually shrinks just a little, makes itself a little fatter to allow more signals to be caught! please excuse the ingrates, one day they will learn all this techy stuff!

A couple of other hints....

Most (but not all) of the "f/wit" talk is on channels 1 to 8 as these are the repeater channels, ie they are retransmitted by a fixed location base station (a "repeater") in order to get wider coverage. These are also known as duplex channels. They are (generally) not suitable for vehicle to vehicle (convoy) communication. Note that channels 31-38 are set aside for duplex (repeater) operation in conjunction with channels 1 - 8 so these channels (31-38) should not be used at all. It is a good idea to set set up your radio to skip 1 - 8 and 31 - 38 when scanning - refer to your instruction manual on how to do this. This is also a good way to avoid the f/wit channels

40 (primary) and 39 (secondary) are usually the truckies channel and 18 is the caravanners channel but for convoy use it is often better to use some other pre-arranged channel. To the best of my knowledge these channel allocations have no legal status so that no one can (in a legal sense) tell others to "get off our channel"

The operation of the radios varies from model to model so it's a good idea to note the brand and model type and to quote this when seeking advice on its use on forums such as this one.

PS I started typing up this post before smokeydk posted his table of Channel "allocations"

Dont listen to Davo...Hes worse than Ducky.....LOL.......heres what info you need UHF Radio is a form of ground wave communication that is highly recommended for coastal, outback, warehouse and business communications in Australia. This form of communication is on the FM Band which supplies superior voice quality and less ambient background noise. Definitely a more professional type of communication than the 27Mhz CB. The other beneficial factor with UHF Radio is the public repeater system throughout Australia. With these repeaters, range of UHF Radio is improved drastically allowing far more flexible use of the radio. Features like scan, selcall and scrambler mode once again gives the user far greater flexibility for any given situation. UHF radio is available in handheld or mobile units. Listed below are brief explanations of the main features found in a UHF radio. SCAN Scan is a feature that is extensively used in highway and outback communications for gaining the maximum information on this band of radio. There are two types of scan on each scanning UHF Radio. Group scan allows the user to program any channels he or she desires into the scan function. This type of scan is commonly used for gaining the maximum information whilst on the road. A common scan is CH 1-8 and CH 40. Channels one up to eight cover all repeater stations throughout Australia and channel forty is classed as the highway channel. Open scan allows the user to quickly scan all forty channels continuously. This is most commonly used in an emergency situation when communication is needed with anybody that can help your current situation. SELCALL Selcall is a feature that is designed more for the business user but can also be a handy feature if you are travelling with more than one vehicle. Selcall stands for Selective Calling System which allows the user to call each individual radio separately or as a group. This system uses coding that is transmitted to the other radios in the group to raise an alarm on the corresponding radio. Thus letting the other user know that he is being contacted. For a more in depth look at this feature please feel free to contact us at Olbis World - Communications Division. DUPLEX (Repeater Function) Duplex is the term used for UHF radios for repeater use. Duplex simply means that the radio is transmitting on a different channel than what it receives on. Eg. Channel 1 repeater .The radio will transmit on channel 31 and receive on channel 1. All repeaters in Australia for UHF radio are located on channels 1- 8 duplex. Any current model UHF radio has this facility standard. UHF ANTENNA The antenna is an extremely under rated piece of equipment to be used with the UHF Radio. This particular part of your system plays one of the most important roles in your communications package. The right choice of antenna can improve performance considerably and must be chosen carefully. See our "UHF Antenna Page" for detailed information about the various models that are available. HIGHWAY CHANNEL The highway channel for UHF Radio is on CH. 40. This is most commonly used by the trucking industry and the general public for highway travelling. Channel 29 is also used by Interstate transport on the Pacific/Princess Highway in NSW. Dave

29 is used on the Pacific and also F3 by Sydney Brisbane runners .
As for 29 on the Princess not to sure but think not .
