Sunset in 5H1 =  1547z                Grayline at Sunset :  342° / 162°
Sunrise in 5H1 = 0323z                Grayline at Sunrise :   18° / 198°


Particular attention will be paid to remote areas and countries with limited propagation openings to Zanzibar. Please always respect operator's intructions and avoid making duplicate contacts in order to give everybody fair chances to make a contact.


Frequency plan (+/- QRM)
Propagation forecast (with SFI=75 and Kp=3)

All simulations made for a 100W station and a dipole elevated at a half wavelength at your end


All times are in UTC, best hour is shown in bold
ex : "1330-1400-1530"
means contact shall be possible from 1330z to 1530z with a maximum at 1400z



Red = Nothing but best hour advised
Dark Orange = Very difficult
Light Orange = Difficult
Yellow = Moderately difficult
Light green = Moderately easy
Green = Easy
