Yep ! :)
... and lots more.
Nice!
Shouldn't it look more like the one I have attached for the duplex channels?Quote:

This is the one from the Icom users group.

I'll post up something shortly.
The KG-UVD1P radio works slightly differently to a fixed program 40/80ch uhf radio you'd buy in a store, in that it has no simplex/duplex function/switch.
Simplex = Radio recieves & transmits on the same frequency.
Duplex = Radio recieves on one frequency -A but transmits on a second frequency -B. (on a specific number of channels only)
Duplex is used to access a "Repeater" station. A repeater recieves your transmission on frequency A, but rebroadcasts it on frequency B. People hear your transmission by listening to frequency B. They respond on A, and you hear them on frequency B. This allows you a much greater communications distance.
On a fixed program 40/80ch radio, when you activate the "Duplex" function, the split between the frequencies is setup automatically so the radio will transmit & recieve on different frequncies. These frequencies are fixed.
On the KG-UVD1P you have to program both the transmit & recieve frequency for each channel. Since there are 80 channels when the radio is in simplex mode, there will be 80channels with their transmit & recieve frequencies the same.
To access repeaters, the radio now needs to operate in duplex mode. Since we've already used up the first 80 positions in the radio programming the 80channels in simplex mode, we now have to program the duplex channels in to the channels positions above channel 80 on the radio.
There are 8 channels allocated for duplex/repeater used on a 40ch unit. 01-08
There are 16 channels allocated for duplex/repeater use on an 80ch unit. 01-08 and 41-48.
So on the KG-UVD1P programmed for 80channels, channels 81 thru 96 become the 16 repeater channels. They are setup with different transmit & recieve settings. Now, when your in duplex mode, the recieve channels frequency is the same as its channel number on the radio, but the transmit frequency is used from another channel! .... so ...
Rpt ch 1 - Recieves on ch 1 / Transmits on ch 31
Rpt ch 2 - Recieves on ch 2 / Transmits on ch 32
.
.
.
Rpt ch 8 - Recieves on ch 8 / Transmits on ch 38
and
Rpt ch 41 - Recieves on ch 41 / Transmits on ch 71
Rpt ch 42 - Recieves on ch 42 / Transmits on ch 72
.
.
.
Rpt ch 48 - Recieves on ch 48 / Transmits on ch 78
(compare the frequencies in the attached file)
Channels 31-38 and 71-78 are the repeater inputs - Do not use these channels for simplex transmissions as you will interfere with conversations on channels 1 to 8 and 41 to 48 (duplex mode). (the same can be said of the repeater outputs and simplex)
I've attached an 80channel setup from my KG-UVD1P. (rename .tw)
This will setup your KG-UVD1P as an 80channel UHF CB radio.
Here are some notes on the setup how/why ...
Ch1-80 are simplex. Ch81-96 are duplex.
Scanning is setup to scan all duplex repeater channels & all other channels except the repeater input/output channels setup as simplex channels (01-08/31-38 and 41-48/71-78 - any traffic on these channels will also be on radio channel 81-88/89-96 - duplex), the data channels, and the (3x) reserved channels.
The channel labels are as follows
Ch1-80 - UHFxx (simplex)
Ch81-96 - RPTxx (duplex)
The last letter after the channel labels are ...
R - channel is used for repeater access in duplex mode (avoid using unless there are no repeater stations within range so as to prevent interference)
E - Emergency Channel
T - Travelling channel (10 - 4WDers/Convoys/NP's/Clubs - 18 - Caravans & Campers convoy channel)
C - Calling channel
D - Data transmission channel
H - Highway channel (29 - Pacific & Bruce Highways - 40 - Truckies channel)
B - Broadcast channel (UHF CB Emergency Broadcast network)
Channels 61-63 are reserved for future use. They are programmed to recieve but not to transmit. Channels 22+23 (the data channels) are transmit disabled as well.
Hope this info and the attached file gets new users off to a flying start ! :)
Hi I'm about to order one, Will I be able to get help here to set it up? are the VHF channles useful? ( Happy to get a licence if needed) I cant seem to accsess the links referring to the frequency's all I get is garbage when I try? comes up in notepad as a long list of letters & No's? Are the suppliers ok,
Andrew, the file is a programming file for the radio. The file extension used is .tw but the board won't let us upload .tw files, so we've renamed them as text (.txt) files. You open this file using the programming app' that comes with the radio (after renaming it to a .tw file.
Yep, you'll get help here. Legally all you should access is the 477mhz UHF frequencies. If you sit your Ham licence, then you can legally work the relevant Ham frequencies this radio can access.
For $100 I wouldn't be too worried :)
