A friend of
mine (no, it wasn't me), has bought a pair of these radios. He has been unable to make them work so he asked me to try. I have to say these are the most complicated pieces of gear I have ever seen and the detailed Instruction Manual is less than helpful unless you have three university degrees.
Does anyone out have this brand and know how to set up to receive UHF channels?
Steve

Does your mate have an amateur licence? It appears these are being sold as amateur radio equipment and they are not type approved for use in Oz on commercial or CB bands. One site indicated they had a 7 W Tx OP so definitely not for use on CB.
I would suggest you steer clear of those radios..

Hi Peter
I don't want to hijack the thread - but is there a reason why 5 watt is the max Tx?
Cheers

Anthony, two way radios are regulated in Oz to have an orderly working situation. One thing that assists is to limit the power to what is necessary for the intended service areas of each service. If there was no constraints on Tx power then we would be bombarded by the cowboy operators with their "Californian kilowatt transmitters."
The CB Class Licence -
http://www.acma.gov.au/WEB/STANDARD/pc=PC_287 - only permits a Tx OP of 5 W. (The insert Link function does not seem to work for me. You will have to copy and paste.)

My knowledge of two way radios consists of making sure they are turned on, on the right channel and pressing the TX button to talk to someone. So that is the sum total of my qualifications...lol.
However, having a look at the TYT home page and their specs for the TH-F8 models show them as listing the outputs as 4w(H) 0.5w(L).
I wonder if someone is....lets say "overselling" these units.
That aside and allowing for the fact that maybe they can't/will not talk to another set of a different brand and MAYBE are illegal to use to Tx in Australia why do they not want to talk to each other?? I assume they both "talk" the same lingo (;-))

Hi Steve
I have just had a look on our friend Mr Google.
I would be very careful and make enquiries if these radios are legal to use here in Australia, with the first big NO, NO is the 7w output printed on the box, as in Australia, the Maximum is only 5w legal transmitted power.
I have a little knowledge on the UHF system, but what I do know for fact is that the 80 Channels that are now available here in Australia and the old 40 Channels what we had before are only usable and legal to use here in Australia and New Zealand, with the rest of the world using different frequencies.
I know that there was an issue where one of the Major GPS manufactures had a combo UHF/GPS all in one unit. When people were buying them from eBay, they were useless here in Australia, as yes they had 40 UHF Channels, but not the Australian frequencies.
Buyer be Ware.
Cheers
Stephen

The other thing is they have to be "C Tick" approved for use in Australia.

Hi Phantom,
Had a quick look on Google and came up with these specs.
Specification:
Item number TH-F8
General
Frequency Range 70-108MHz(FM Receive only)
136-174MHz(RX/TX)
400-470MHz(RX/TX)
245-246MHz
350-390MHz
470-520MHz
If you can't get them to talk to each other - I can't help you; however, if your issue is getting them to talk to other UHF sets, there might be a problem with the receive/transmit (RX/TX) frequency range - might not be in the range used for Australian units which I think is 477MHz? Just a thought?
Cheers
Rob K

Steve,
Hope this is of help to you and your friend.
Your friend has purchased Amateur Radios. Type TH-F8 into Google and go through the list until you see one where they are talked about under YTube where you will see exactly what they are.
Unless he is a Licensed Amateur (like me) he will not be able to use them. It maybe best for him to try and sell them to an Amateur Operator.
Cheers P&J

Putting it simply, your mate bought the wrong tool for the job based on his knowledge and qualification.
