Hi Tam,
Conor, (Northern Crusader) has pointed you in the right direction regards programming, you don't need all the leads/software or such and can program it directly from the front panel. You don't need all the repeaters programmed in either and can just program the ones you want whether near you or on any travels.
Worth a search for any tutorial videos on how to do this. (There are a few.)
The nearest repeaters to you are :-
GB3KE - 2m - https://ukrepeater.net/my_repeater.php?id=2366
GB3KW - 70cm - https://ukrepeater.net/my_repeater.php?id=2798
GB3GL - 70cm - https://ukrepeater.net/my_repeater.php?id=3037
Click on any of the above links to get to the RSGB UK Repeaters site for the details/frequencies.
You can also programme some simplex frequencies in such as 145.500MHz (the 2m simplex calling channel) and might be worth popping in a few more of those channels so you can QSY off the calling channel. 2m activity can be quiet in areas but others bristling with regular nets so worth a go.
Worth having a play to see what activity is like in your area and although repeater work is not everyone's cup of tea it's worth a bash as you just never know....you might enjoy it.
(It does at least get you on air and start using your licence privileges.)
Remember, have fun and enjoy yourself.
All the best,
Victor
