Hey guys just need some info...

Im very new to "Amateur Radio" so please be kind and treat me as a total newbie.

I got a QuanSheng TG-UV2 dual-band (VHF/UHF) FM hand-held transceiver from china it has very good reviews. I wanted to see what amateur radio was all about before i spent a lot of money and going for my test. I belive that your allowed to scan but not trasmit without having a licence (please tell me if i have been misinformed)

I got this thing to scan and pick up the local taxi firm and thats about it. I hear a lot about repeaters but dont understand how to get them up on my radio. All i want to do is to start understanding the way you set things up and see if i get an interest in it all.

So if anyone has the patients to go into detail with it all with me that would be great.

Cheers guys.

Amateur radio is a HUGE topic.

To answer your specific questions:

Yes you can listen, even with a TX capable transceiver. Just don't be tempted to transmit. Amateurs tend to have a very good memory for voices... [-X

The 2m and 70cm repeaters (all repeaters in fact) require you to listen on one frequency and transmit into them on another frequency.

So you might listen to a repeater on 145.700, and you would hear everybody talking through that repeater. When you come to transmit, you would need to transmit into the repeater on another frequency (145.100 or what is called a -600kHz repeater shift), so it can listen and then "repeat" (simultaneously) your smaller signal with it's bigger and higher signal (the reason you use a repeater in the first place).

To prevent 'repeating' unwanted signals (random noise), repeaters use a thing called CTCSS. Basically, this is a sub audible (humans can't hear it) tone that the machine can hear and acts as a 'key' to open the repeater. Without the correct CTCSS, the repeater won't repeat your signal. It will just ignore you.

To listen, you don't need to worry about CTCSS, it's only important when transmitting.

Here is a list of all of the UK amateur repeaters: http://www.ukrepeater.net/index.html

It's got a google map feature, so you can see what's close to you.

Most repeaters 'ident' (send out a morse code burst telling you which repeater they are) every fifteen minutes. If no one is talking through them, you wont know they are there until they 'identify' themselves.

Hope this helps a bit.

Hey mate sorry for asking this i know it must sound very lame...

My radio dose

Frequency range: FM: 88-108MHz (RX); VHF: 136-174MHz (RX/TX); UHF1: 350-390MHz (RX/TX); UHF2: 400-470MHz (RX/TX); UHF3: 470-520MHz (RX)

So what Repeaters would i be looking for?

Cheers mate

The repeater you have posted the link to (GB7WP) is a D-Star digital repeater, you need an Icom D-Star equipped radio to even receive the audio.

Leave the GB7xxx repeaters off your search list, just look for the GB3xxx repeaters on 2m and 70cm.

As long as you listen on the repeaters output frequency, you should be fine, just be aware that the repeaters aren't used much these days, and you are more likely to hear people on during the weekly commuting time and perhaps weekends.

You will hear very few using the repeaters during the weekday or weekday evening, generally speaking.

One word of caution, it is common practice for repeater keepers (the person who maintains the repeater) to have a voice activated digital recording system on the repeater, so any and all transmissions through it are recorded. This has become common practice due to Ofcom only responding to evidence rather than reported violations when abuse occurs. This is worth knowing if you are thinking about having a *play* with one.

I'm not preaching, just letting you know the score. :wink:

You will find the majority of amateur radio operators working the HF bands, evenings and weekends. These are the bands used to communicate with people all across the world, so they have much more appeal and variety to people with limited radio play time I guess.

The transceivers are a lot more expensive (£500+) than the VHF/UHF transceivers (£100+), and the antennas are a bit bigger (OK, a lot bigger!).

suggest you join your local radio club and first pass the foundation get a call sign then you are good to go and a lot of the members will have the same radio so you will be sorted

the 145.750 is the gb3mp repeater in north wales

*King* *King* *King* *King*
