Description

This App will show the behavior of the E and Freflection layer on world wide short wave propagation between 1MHzand 30MHz. The World-map is computed and displayed at a resolutionof 1 degree for the selected map type, month and solaractivity.
To compute the 24 maps of the day a Galaxy SII will need about 5seconds, Touch the black area after the message vanishes to see themap. At each touch in the right area the day time (UTC) isincreased, in the left screen area UTC is decreased. Longitude,Latitude and the computed value at this location is displayedalso.
Gray-line (dawn zone) and the position of the sun is adjusted foreach hour.

The map type are:
f0F2 maximum vertical F-Layer frequency (MHz)
Height of Gyro at HmaxF2 Shimazakis formula (Km)
Height of F-Layer bottom HoF2 (Km)
f0E maximum vertical E-Layer frequency (MHz)
upper deciles of sporadic E frequency (MHz)
Median of sporadic E frequency (MHz)
lower deciles of sporadic E frequency (MHz)

for all months and sun spot number 10, 30, 50, 90, 120 and150

This map sets are intermediate results from the development of aHF prediction App coming soon, stay tuned.

The first version of the HF prediction app is here now:
MyHF_Map will compute MUF, FOT and HPF coverage maps for theentered location and sun spot number in minutes !
It's available now, more features will follow.

MyHF_Map HAM Radio MUF maps 2.0 APK
agtim.ch
Short wave 1-30MHz area coverage predictionHPF MUF FOT for HAM radio operators.With this App you can create the coverage map for HPF, MUF and FOTbased on the location QTH of your radio station TX defined bylatitude and longitude and minimum radiation angle.Coverage maps are produced by calculating a huge amount ofpoint-to-point circuits from the transmitter to a world widereceiver grid of 88 x 64, This are 5632 point-to-point calculationsof the HF path for 24 hour of the day. A SAMSUNG Galaxy II willneed less than 1 minute to compute the maps, valid for the selectedmonth.The used algorithm are based on the HFMUFES FORTRAN library asused by HFMUFESW, IONCAP or VOACAP but ported to JAVA classes. Thelast computation is retained and a new computation will be done atchanged entry values only. Ionospheric data are inside the JAVAclasses for all months and sun spot number 10, 30, 60, 90, 120 and150During map view you can switch between HPF, MUF, FOT and eachhour of the day (UTC). The display will be on as long the map viewis shown. There are a bunch of different color palettes that can beselected. The current selection is retained at App exit, so youmust go back to the main menu to have the map saved. Later when youtouch draw the map button again the the last version is shown. Tocompute again, modify an entry value, month or ssn.Gray-line (dawn zone) and the position of the sun is adjusted foreach hour.At each touch in the right area the day time (UTC) is increased,in the left screen area UTC is decreased.Watch the touch area functions displayed during thecomputation.At the Highest Possible Frequency HPF, communication can besupported on 10% of the days (3 days) in the month. At theFrequency of Optimum Traffic FOT, 90% of the days (27 days) in themonth and at the Median Maximum Usable Frequency MUF, 50% of thedays (15 days) in the month.
