- | * We got a 40M inverted-V working, and it seems to tune alright 80-20. | + | Antennas tested thus far: |
- | * There is space for routing coax down the lift shaft alongside the SDR stuff. Possibly. | + | |
- | * Further research is being done on a boatanchor radio. CN may have enough spare cash after getting his HF rig to donate to the lab a FT101, but don't quote me on this. | + | |
- | * **TK**: In terms of equipment for a more permanent and higher powered radio, Jaycee are getting a lot of stock in second hand and we can ask them to keep an eye out. See http:// | + | |
- | * **TK**: I have an antenna tuner now which we could temporarily site on the roof (it’s battery powered). | + | |
- | * **TK**: We could build a linked dipole or fan dipole – I’ve got some dipole centres for this. I also now have a 1:1 current balun that should reduce the coax shield pickup. | + | |
- | * **TK**: I was considering a longwire antenna may be a good solution as it run up to the roof with the balun on the bottom and a ground connection where the lightning rod connects to ground. | + | |
- | * **CN**: I have discovered the lab has *no* VHF/UHF coverage outside Summerhall. GB3FF was lit up on the evening of the 19th, and we were oblivious to it! As dry runs for actually running antennas down Summerhall' | + | |

- | * 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. | + | * TBD. Now we have a radio we can start looking at what Summerhall will let us install |

- | * 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. Tim K is registered through volunteering work with the Red Cross. | + | |
- | * 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. | + | |
