Propagation forecast in August by VOACAP online says that the window may open ........
For EU
05z - 07z on 14MHz, 08z - 10z on 21MHz, 10z - 12z on 18MHz, 14z - 16z on 14MHz and 21z - 23z on 14MHz
For NA
00z - 06z on 21MHz, 04z - 08z on 18MHz and 06z - 13z on 14MHz
This is my operating plan at present time. As you know KU2F/VK4 is now active from OC-187.
He says that best time/freq is 21z - 23z on 14MHz for EU and 11z - 13z on 14MHz for NA.
Anyway your suggestion and advice will be very much appreciated.
Lizard Island does not provide internet service in the room. It is only available in guest lounge.
Please do not send me direct e-mail or request message on DX spot during vacation because
I can not read anything online. Stay tuned.....

JA1NLX/VK4 from OC-187 updated
This is primary antenna I expect. It consists of mini tripod, 4 antenna arms, LowBand coil and Long whip. All come from Buddipole. Max total length is about 5m. I have 1/4 wave length on 14,18,21,24 and 28MHz. 2.5m x 80 radials and various capacitors attached for better matching at feed point.
I used this antenna in FK/JA1NLX 2009 and JA1NLX/VK4 2010. It has worked very well with a little troublesome for band changing.
JA1NLX/VK4 from OC-187 updated
This room is one of Sunset Point Villa which I booked. Maybe I have great sunset view !
I do not know whether I have good room for antenna setup. The antenna will be 5m long Buddistick 1/4 wave vertical for 3.5-28MHz or random wire with ATU.
Lizard Island Resort says HAM will be always welcomed if he/she set not big antenna up !
Stay tuned.....
