All current 146-147MHz band Notices of Variation (NoV) expire on Tuesday the 31st of October. Ofcom has agreed that the band will be made available for another year. However, to continue to use the frequencies you must obtain a new NoV. These are available free from the RSGB website via www.rsgb.org/nov
I also refreshed my 71MHz NOV as my original was due to expire in a couple of weeks.
Again, 100W ERP. My antenna has (allegedly) 9 dBd gain allowing me to run 12.5W. That's just a bit more than my RA30H0608M module can manage with good shoulders so no problems there. The closest I have been to Scotland of late is the yard, so no problems there either.
These two are a bit more challenging.
(c) The use of the Station in the Authorised Band must not breach the agreed international coordination limits applicable to the Authorised Band.
(d) If the Licensee can demonstrate that the use of the Station in the Authorised Band complies with relevant provisions of the Harmonised Calculation Method agreement, it may be taken to show that the use of the Station in the Authorised Band is not breaching the agreed international coordination limits applicable to the Authorised Band.
