Hello and welcome, hacker public radio audience. My name is Mr. X, and as usual, I'd like to start by thanking the people
of HBR for making this service available. If welcome, check the show with more shows we want to do with. The show is provided by the community for the community.
It's actually very easy. They've gone to a great deal of effort to streamline the whole process, and it's actually quite easy.
The hardest part I find is getting down to write in the show notes, just about picking up microphone and hitting the record button.
I must have something interesting that we don't love to hear. Anyway, this show is all the fault of Ken Falons.
I was listening to one of the community news episodes, and he was commenting on a previous episode that I did about the Wolfing UV-5R handset.
That's a VHF UHF hand held video that can be used either for amateur use or for taxis or PMR or whatever. But anyway, in the community news, Ken Falon was commenting that I said,
that I didn't want to go into some of the features and detail, because I'd be there all day explaining it, and Ken said,
no, no, I wanted to say, tell us all about it. I want to hear all about it and great detail, even though of course, Ken hasn't got one of these videos, because as I said, it would be legal for him to have one of these videos and in the Netherlands.
This is all Ken Falons fault, so you know who to blame if you're fit up listening to me, flatling on about the BoFing UV-5R.
So I'll begin at the beginning, and I don't have any parts to start to whether it be just one part or multiple parts, but here goes anyway.
So I thought at this point I'd go through a typical example of using the BoFing UV-5R handset, so I've picked up my hand and let's just start by turning it on.
Obviously, the volume controls at the top right hand side, as you view the thing, and I'm going to edit it clockwise, and you'll hear a click as it comes on, and an announcement, so let's give it a go.
So there you go, you get the double beep that signifies that the video is powered up, and then an announcement that says channel mode.
So you've got two modes of operation, either channel mode operation or frequency mode operation, and frequency mode you just directly input the frequency you want to go to.
This is in channel mode, and these channels are obviously pre-programmed at some point, and so that's why it comes on and says channel mode.
And I thought I'll start by going through an example of giving a call on a samplex frequency, that's just a, you're transmitting and receiving in the same frequency.
And here in the UK the samplex calling frequency would be one full on VHF every high frequency would be one four five decimal 500.
That's 145 megahertz, 500 kilohertz.
At the moment it's saying 145 decimal 487, and that's channel 26 just happened to be the, the channel of the video was sitting on, so we'll push the up button once.
Two, seven.
And the video announces of going up to channel 27, and in my particular video the way I programmed it, channel 27 happens to be 145 decimal 500.
So the next thing I've been thinking well okay, I want as many people to hear me as possible, so I've noticed that there's a small L appearing in the top left hand corner for this place, I'm obviously in low power.
So I'd better select high power, and to select high power, you just momentarily push the hash key.
The hash key's got, it's got hash on it, it's got wee blue key on it, which is for locking the keyboard, which happens if you hold that key down, but if you just momentarily touch it, it also happens to be short cut to take you to high power.
So just touch that now.
There we go, and you get the beat telling you that that's been inputted in the L disappears on the display.
There's not an H to say high power, it just disappears the L.
So now that's already to go, so I hold the radio in my right hand and squeeze the push to top button on the side of the radio and give an announcement to hear we go.
Hello, this is GM4 MRX, listening on S20 for any calls, and that's that's on S20, obviously it's not around, so that's fine.
So, now we can try giving a call on one of the local repeaters, and there's a local repeater here in the 1st of 4th, GB3 FF, and that's on decimal, it's 1, 4, 5, decimal, 600, which will just go to that happen, let's just see now.
2, 8, 2, 9, 3, 0, 3, 1, 3, 2, 3, 3, 4, 3, 5, so...
So that was the repeater, GB3 FF that you were listening to the other I-daint, the more I-daint, which the transmit every so often, just happened to be on as I was searching channels there.
So there you go, that's now something on 1, 4, 5, decimal, 600, and if I push to PTT switch then the radio drops by 600 kilohertz and it transmits on 1, 4, 5, decimal, 0, 0, 0, and the repeater is listening on 1, 4, 5, decimal, 0, 0, 0, 0, for any reception.
And if it receives a signal then retransmits that signal out back when decimal and 1, 4, 5, decimal, 600, so that's 600 kilohertz higher than what it's listening on.
Because you can't transmit them to see when the same frequency one so obviously. So I'll just give that a go, so let's just see.
Hello, this is GM4 MRX testing access.
So there you go, that was me lifting the repeater there, the repeater picked up my signal and you get a pip.
And we're telling you that it's waiting for you to call in sort of thing and after a period of time it just drops a transmitter and goes back to listening again.
So that is basically all there is to it.
Actually I just turned that off. Maybe go back off again.
Yep, that's actually all there is to it.
It's really quite easy to use. Okay, so if you're looking for information on the both UV-5, obviously you can look at the manual that comes with the radio.
But I'd also recommend looking at there's a project called the Chinese video project and I don't know very much about it.
I don't know whether other models are being covered or not, but it's certainly covers the both UV-5R.
And that's available at HTTP colon slash slash radiodoc.getHub.com.
I'll hopefully put that in the show notes if I get a chance.
So that takes you to the Chinese video project for the both UV-5R radio.
And that's being created by I think it's Lennard, Lidberg, and it says this work is licensed under Creative Commons attribute share like 3.0 unported license.
Looking through the document, the author was planning to cover the excellent open source programming software chart.
Which allows you to program your radio from a PC. It's a multi-platform, it's multi-platform and it's available for Linux.
Here's what it says about Chup. Chup and the upcoming revised edition.
Originally, I intended to include a whole section in the programming chapter dedicated to the free and open source programming tool Chup.
But unfortunately, I couldn't for the life of me get it playing with my hardware despite trying three entirely different setups.
Chup will therefore have to wait for the revised edition of the book, which in turn will have to wait for me to get Chup working.
Okay, so I remember reading somewhere that people were having problems getting the programming cables working.
And I think the cable emulates a serial cable via USB.
I'm led to believe that there are clones of these cables doing the rounds.
Apart a lot of the cables have counterfeit chips within the cable that Windows detects and refuses to work with.
Linux, in other hand, completely ignores this and works within a cable.
This may explain the problem's author was having getting a really good programming chip.
Here are some basic concepts from the Chinese serial project BoFing UV5, our manual that I thought you might find useful before
Delving into the details for the BoFing UV5 transceiver.
So from chapter 8, it talks about selective calling.
So it says, explain selective calling.
Sometimes when you're working with larger groups of people using the same channel, things can get very crowded, very fast.
To minimize this problem, several methods of blocking unwanted transmissions on your frequency have developed.
In general, there are two forms of selective calling and two radio systems.
Group calling and individual calling.
Group calling as the name suggests is a one too many form of communication.
Every radio in your working group is configured the same way and any radio will make contact with every radio in the group.
Individual calling, sometimes also known as Paging, is a one to one form of communication.
Every radio is programmed with a unique ID code and only by sending out a matching code, can you get the radio to open up to your transmission.
The BoFing UV5R features three different ways of group calling, CTCSS, DCS and toneburst.
The BoFing UV5R does not feature any form of individual calling. Using these features does not mean that others won't be able to listen to any of your transmissions.
They only provide a method to filter out unwanted incoming transmissions.
Any communication made while using these features will still be heard by anyone not employing filtering options of their own.
Also, you cannot change the CTCSS or DCS settings while in memory mode.
CTCSS and 1750Hz toneburst are also popular methods among amateur radio operators to open up repeaters.
So that's quite interesting, quite useful.
I'll delve into some more detail, obviously, from a bit further on.
Chapter 10 programming. Memory channels are an easy way to store commonly used frequencies so they can easily be retrieved at a later date.
The BoFing UV5R features 120 memory channels, each can hold, receive and transmit frequencies.
Transmit power, group signaling information, bandwidth, A and I slash PTTID settings, and a 6 character alpha numeric identifier or the channel name.
So within that, there's manual programming. So it says, for manual programming, manual programming is somewhat fiddly until you get used to it.
Especially when programming in duplex channels, note that the A and I and S code IDs can only be set from a computer.
When programming channels, it is important to remember that you can only save memory channels when working on the upper display in a VFO mode.
That's handy to know, isn't it?
To create a new channel, start by switching your radio to frequency VFO mode using the key.
When in frequency VFO mode, select your desired receive frequency using the numeric keypad,
after that, use a menu system to configure the final details of the channel you're wanting to program to memory, such as transmit power, bandwidth, CTSS or DCS and more.
For more information, how to use a menu system, see chapter 4, working with a menu system and appendix B.
Information regarding how to set up CTSS and DCS can be found in chapter 8, selective calling.
Chapter 11, repeaters.
A radio repeater is not a bit of time-sever and affects location.
Usually mounted high up on a hilltop or on a tall building.
But sometimes it operate within buildings for internal use.
A repeater takes one signal and relays it, usually after amplifying it by orders of magnitude.
This can be very handy, as isn't able to use a small, low powered handheld 2-way transceiver, such as a both-fing UV-5R to reach create distances.
Whether you're a commercial business or government user or an amateur radio operator,
chances are you'll be dealing with a repeater system sooner or later.
To find out what settings to use to use your local repeater, ask your employer or someone at your local IARU membership organization for details.
A common type of repeater is a duplicate repeater.
In a duplicate repeater system, the repeater transmits and receives simultaneously, but in different frequencies.
To utilise a type of repeater, you radio have to be capable of transmitting and receiving on different frequencies on the same memory channel.
How you use this kind of repeater is by setting the received frequency of your radio to the output frequency of the repeater
and the transmit frequency if you radio to the input frequency of the repeater.
Often times the transmit frequency to use isn't explicitly stated, but rather an offset relative to your received frequency is specified.
This is conveniently enough, also how the both-fing UV-5R, natively handles the repeater set up by specifying offset rather than transmit frequency.
Chapter 12, automatic number identification.
In dispatch environments, it's common to have a system in place that will allow reduced to automatically identify themselves to the dispatcher.
This is known as automatic number identification, or sometimes PTT ID.
Since the radio sends a data box to containing the ID code at the beginning or end of transmission,
the both-fing UV-5R, which is a DTMF signaling for an A and I implementation, automatic number and identification.
13, amateur radio setup.
In contrast with commercial radio operators, you often need various specific requirements to be compatible with a very specific radio and implementation.
amateur radio operators tend to need the broadest possible settings in order to be compatible with as many systems as possible.
This basically implies turning all the fancy features that you typically might need for commercial things set for commercial setups off.
At a typical amateur radio setup, the following settings would be recommended. Set bandwidth to wide, menu item 5.
Turn DCS and CT CSS off, menu item 10 through 13.
Turn A and I DTMFST is called PTT ID off and PTT LT to 0 milliseconds.
Menu items 15 through 17 and 19 through 20. Turn off scrolls till elimination STF features, menu item 35 through 37.
Turn Roger beep off, menu item 39. For further information, see appendix B, menu definitions and chapter 4 working with the menu systems.
I hope that gives you a flavour of the sort of things that's inside the Wolfing UV 5R, Chinese, which is a call again. Let me just get this right. It's called the Chinese video project Wolfing UV-5R.
I mentioned that when I first talked about the Wolfing UV-5R, I said that they've got diagrams of the radio and it was so accurately produced and so well rendered.
I thought it was the original commercial manual that came from the manufacturer, but it wasn't, and I believe it was rendered in the landscape.
Anyway, there you go, it's very impressive piece of documentation, well worth the read. I think that's enough just to cover some basic ideas about using the handset with amateur radio using mind.
Okay, so that's enough for part one of the Wolfing UV-5R. As I say, it's going to be a long and rambalene, it's all kin-fallens fault. Hopefully it'll be advantageous to a few people listening.
If you want to contact me, I can be contacted at MrXHPR at googlemail.com. That's MRX, ATHPR, the Atsemble, googlemail.com. So until next time, thank you.
I goodbye.
To listen carefully, listen carefully, and do what you can about to see and a point to see, and I will uneasy you, and yeah, you will produce a chauffeeeil for it.
