Subject: [HIham] Hawaii National Parks on the Air, Fri April 1 - Mon April 4,
 Kalaupapa Molokai
Message-ID: <56FAC529.20406@hawaiiantel.net>

All is GO! for the activation of Hawaii's first 2016 National Parks On 
The Air operation at Kalaupapa, Molokai.  Five operators will activate 
two HF stations will from Friday, April 1 through Monday, April 4 in the 
vicinity of Kalaupapa airport and lighhouse.

Kalaupapa is the rarest of counties on the air, as there's no permanent 
HF operations in Kalawao county.  Operators may be permitted on 
Kalaupapa peninsula only by invitation.  A QSO contact qualifies for: DX 
(KH6), WAS, County Hunters, Lighthouse.  Since no direct VHF/UHF 
contacts are expected from Kalaupapa and repeater contacts do not 
qualify for awards, no VHF/UHF station is being arranged as each piece 
of equipment, food, supplies and trash must be air freighted in and out.

The team consists of Bev AH6NF, Kimo KH7U, Jim WH6GS, Bart KH7C and Ron 
AH6RH.  One of the objectives of the team is to hold a ARRL VE license 
exam for the four students who have been studying remotely via the 
Internet.  We are hoping to upgrade one Technician to a General license 
during our stay.

While this are no Wi-Fi or Cellular services available to the team at 
Kalaupapa, the team expects to be able to improvise and post updates to 
Facebook of current operating conditions.
