There are a number of projects in the pipeline relating to amateur radio; these will be updated as they progress. | There are a number of projects in the pipeline relating to amateur radio; these will be updated as they progress. | ||

- | * **TK**: I have an antenna tuner now which we could temporarily site on the roof (it’s battery powered). That would allow us to try a doublet on a few different bands and see what the noise level is like without significant SWR losses in the cable drop. We could also rig a vertical up using the earthing | + | * **Magloop**: |

* Once three of us have Advanced licences, this opens up the possibility of the Hacklab obtaining a Full (Club) licence. Fee for this is £20 (club licences last 5 years) and a callsign of the form MM0xxx will be assigned to the Hacklab. | * Once three of us have Advanced licences, this opens up the possibility of the Hacklab obtaining a Full (Club) licence.

- | * Clubs can then apply as a Registered Assessment centre and we would be able to administer exams/ | + | |
- | * Cannot hold courses (but can hold exams) for u-18s unless DBS checks are done on all assessors. This probably won't be feasible primarily due to cost and/or privacy concerns. | + | |
- | * TH: The requirement for DBS checks depends on the nature and amount of time spent in the role. RSGB will pay for checks for their members where required. | + | |
- | * TH: I don't think it's worth considering assessment or examination options in the foreseeable future. We can consider providing training when we have enough of a community around our ARC, and when we have enough commitment from suitable license holders. We don't have facilities to run exams in our current premises. Best to send people to existing exam centres. | + | |
