Correspondence:
Documents from the Napier City Council regarding the ground lease for the club rooms.
Last signed in 2009 and due for renewal. Conditions remain the same, annual ground rent of near $400 has crept up over the years. Tabled by Stan: documents related to the change over of electric power supply companies.

Finance: Account payable to the Napier City Council for annual lease.
The cost of re-programming the Eprom memory of the Tait radio was paid by Laurie.
He will not pass the charge on to the club and so made the club a $100 donation.

General business:
A reminder by Dave ZL2DW of the forthcoming Christmas dinner, bookings to himself or Laurie. Lee ZL2AL reported that an aerial rotator needed for the club’s new HF antenna system will be donated to the club by himself and Gary ZL2IFB. Originally bought at trademe for $120 for the contest station but now going spare.
Lee also reported briefly on the recent CQ WW contest, about 5500 contacts were made, results to be published when available.
