This is part of our Getting Started section for beginners to amateur radio. Here are some common operating tips and a few of the Dos and Don’ts that can help when you’re getting started on the air.
Using a Repeater
Settings: It’s important to set your radio up correctly. Check the repeater’s output frequency, input frequency or offset, and the correct CTCSS tone where one is required.
A useful source of current UK repeater information is UKRepeater.net.
Listen first: Before transmitting, spend a little time listening. This helps you understand how the repeater is being used and whether a conversation or net is already in progress.
Timeouts: Repeaters normally have a timeout timer to prevent one station transmitting continuously for too long. If you exceed it, the repeater may stop retransmitting your signal. Keep transmissions reasonably short and allow the repeater to reset between overs.
Leave a gap: Leave a short pause after the other station finishes before transmitting. This gives the repeater timer a chance to reset and leaves a convenient gap for another station to call in.
Calling: You don’t normally call “CQ” on a repeater. A recognised way of putting out a call is:
“This is M7QQQ listening through GB3DA.”
You can also add something such as “for any contacts” if you wish.
If nobody responds after a few calls, give it a rest for a while rather than repeatedly calling. Someone else may want to use the repeater.

Hints – Joining a Net:
If a net is in progress, listen for a while before joining so that you understand how that particular net operates. When you’ve joined, wait until you’re called rather than transmitting over somebody else’s turn. If the net is busy, keeping your transmission reasonably brief helps to give everyone a chance to take part. Different nets have slightly different styles, so listening first is usually the best guide. |
If you discover that you and the other station can hear each other directly, consider moving to a simplex frequency, particularly if the repeater is busy.
For more on using repeaters, see our Using Amateur Radio Repeaters Guide, or watch this extract from our Foundation Online Training Course:
2m / 70cm Simplex Contacts
The UK FM calling frequency on 2m is 145.500MHz, and on 70cm it is 433.500MHz.
These are calling frequencies, so once you’ve made contact, the normal practice is to move to another suitable simplex frequency so that the calling channel remains available for others.
- Set the radio’s squelch so that weaker signals can still be heard.
- Tune to the calling frequency and listen first to make sure it isn’t already in use.
- Call CQ and give your callsign clearly, preferably using the phonetic alphabet where helpful.
- Pause for a reasonable length of time to allow somebody to reply.
- If nobody responds after a few calls, leave the frequency clear for a while before trying again.
- Once somebody answers, agree to move away from the calling frequency.
- Find a suitable simplex frequency using the current RSGB Band Plan.
- Listen carefully. If it appears clear, ask: “Is the frequency in use? This is {callsign}.”
- If there’s no response, return briefly to the calling channel and tell the other station which frequency to move to.
For examples, see our On-Air QSO Example, including a sample script and training video:
SSB Centres of Activity
For SSB operation, the RSGB Band Plan identifies 144.300MHz on 2m and 432.200MHz on 70cm as SSB Centres of Activity.
These aren’t channels reserved exclusively for calling in the same way as the FM calling channels, so always listen first and follow the current band plan.
Calling CQ on HF
- Check the current RSGB Band Plan to make sure you’re using the appropriate part of the band for your mode.
- Find a clear frequency and listen carefully before transmitting.
- If the frequency appears clear, ask: “Is the frequency in use? This is {callsign}.”
- If there’s no response, call CQ and give your callsign clearly.
- On HF, CQ is normally repeated several times so that stations tuning across the band have time to find you and identify your callsign.
- Using the phonetic alphabet can make your callsign easier to copy, particularly when signals are weak.
- Leave a reasonable pause after your CQ call to allow somebody to answer.
- Once you’ve made contact, you can normally remain on the same frequency provided it is appropriate for that type of operation.
Band Plans
Band plans help different users and modes share the amateur bands sensibly. They identify areas commonly used for voice, Morse, data, repeaters, satellites and other types of operation.
Band plans can change, so it’s better to refer to the current version rather than relying indefinitely on an old printed copy.

Suggestions?
Have we missed a useful operating tip? Add your suggestion as a comment below and we’ll consider adding it to the guide.

Having just passed my foundation licence it would be nice to know what the simplex channel numbers and frequencies are. I used to use CB radio and this had forty channels.
When I have called CQ on the calling frequency and made a contact, how do I tell my contact where to go for a chat. Do I just pick a frequency and give them that frequency or are there recognized frequencies which have been given numbers to make life easier??
Hi Peter,
For this, you’d need to look at the band plan for whatever band you’re looking to use. Assuming you’re asking about 2m, then the calling frequency is 145.500MHz, and adjacent frequencies can be used as per the band plan – see the following video for more on this – https://www.essexham.co.uk/train/just-passed-foundation/

One of the operating points that isn’t clearly covered in detail for me is the handback protocol
im using 2m and 70cm at present
most old hands do it smoothly without thinking but clarification would be useful
This is how i think it should be from listening but i haven’t seen it written anywhere
Callsign theirs , Callsign yours , What your doing “returning” or “back to you”
Point is its always theirs then yours not other way round
or if not just your callsign and what your doing which i find i do for fear of mixing it up.
for me that’s the hardest part to do smoothly and without mixing up the way round it all goes
If I’ve got it wrong please say . Nobody gets upset on 2m but i feel that’s the bit I’m struggling with to do smoothly
Loads of videos about on CQ and repeaters but the handover isnt covered that much

Hi Greg.
There’s no hard-and-fast rule, beyond the requirement in the licence to make sure that you give your callsign “as frequently as practicable”. Best advice I can give is to listen to how others do it on-air and develop a style that works for you.
My style is to end “long overs” with “, “, or ” back to you from “, both of which make it clear that I’ve finished.
In the Calling CQ section after “Listen to make sure the frequency isn’t in use” it should say “Ask if the frequency is in use”. You don’t need to do this on the FM calling channels but you do need to do it on HF.
Must admit, I thought it was clear, as it was in the previous section, but I’ve tweaked the wording for clarity.
Just researching and came cacross this discrepancy about the 2m fm calling frequency is it 144.500 which as per the RSGB band plan is in the simplex channels or as you’ve put it 145.500?
I am struggling with acceptable simplex frequencies after calling CQ on 144.500.
Below 144.500 is SSB and CW only, however contacts have taken me there (like 144.400 and 144.440 – easy to remember and dial-in I suppose)
144.500 Up to 144.845 is simplex and then another simplex chunk between 145.200 and 145.600
UK ‘channel spacing’ for 2m is 12.5khz.
Can we pick any arbitrary frequency within the above ranges or should it be specific frequencies 12.5khz apart keyed on 144.500 (so 144.51250, 144.52500, 144.53750 etc. and then 145.20000, 145.21250, 145.22500 etc.)
That is a PITA to remember and most VHF radios do not have a channelised dial so you would be pretty much dependant on programmed memories much the way we use repeaters.
What is the best practice for this?

Calling on FM is 145.5000 12.5 steps up in frequency
Calling on Digital Voice is 144.6125
Different modes are 144.500-144.794
