Just an update to this thread, I passed the exam on 14th October after it was delayed by a week, but all went well.
Now that I have my M6 callsign I've been working a few distant repeaters over the past couple of days just to see how far I can get on VHF/UHF, from my location using the very basic rig I have. (Boafeng UV-5R & Diamond X50 Antenna)
To the North & West I'm getting into North Wales & Liverpool via GB3CR, also into Buxton & the surrounding Peak District via GB3HH which also touches parts of Manchester as well as Burton on Trent.
To the North & East I am also able to reach in to Derby & Mansfield via GB3DY & Leicester via GB3CF.
I can also access a couple of repeaters in Birmingham but they are a little scratchy, GB3CB & GB3GB & Stourbridge via GB3KC.
The Southern path is somewhat blocked by the Clee hills & I will need to work on this area more to determine the full extent of the range I have in that direction, but all in all Im very pleased what is available to me currently.
Once I get an HF set I expect to really "get out there" but for now I have good local coverage.
