| RSGB Band Plan (effective from 1st January 2018) | ||||
| Access to this band requires an appropriate NoV, which is available to Full Licensees only | ||||
| Note that the current NoVs last for up to one year prior to expiry on 31st October | ||||
| For further information see the 146-147 MHz FAQ or contact vhf.manager@rgsb.org.uk | ||||

| Note-1: Users of wideband modes must ensure their spectral emissions are contained with the band limits | ||||
| LICENCE NOTES: Full Licensees only, with NoV, 50W erp max - not available in the Isle of Man or Channel Isles | ||||
| Note that additional restrictions on geographic location, antenna height and upper frequency limit are specified by the NoV terms | ||||
| It should be emphasised that this band is UK-specific and is available on a non-interference basis to existing services. | ||||
| Upper Band limit 147.000 MHz (or 146.93750 where applicable) are absolute limits and not centre frequencies | ||||
| The absolute band frequency limit in or within 40km of Scotland is 146.93750 MHz - see NoV schedule | ||||
