[CQ-Contest] HFTA, PRN files

[sq7d]

Peter

I am not write about *.PRO files. I write about elevation files for particular country - PRN.

http://www.enduro.idl.pl/HFTA/HFTA.jpg

Closest to SP countries with PRN files are DL, OK and UR. If one lives close to that countries border it may be usefull but not for the rest area (north SP, centre SP ect.).

Here is part of OK-US.PRN file:

Prague, Czech Republic to USA
Elev      80m    40m    30m    20m    17m    15m    12m    10m
1        0.1    3.3    8.8    8.6    9.4    7.4    4.2    0.9
2        5.1    4.6    7.0    8.2  12.4  11.0  12.1    9.6
3      10.2  16.0    6.1    5.4    6.9    9.6  10.7  10.4
4        4.5  10.9  11.1    2.7    5.2    8.1    8.4    7.8
5        1.1    2.4  10.6    2.7    5.7    6.5    8.4  13.0
6        0.7    0.4    3.7    3.1    2.9    5.2  11.6  12.2
7        1.4    2.0    7.0    7.9    4.2    2.7    6.0  11.3
8        3.0    5.1    7.9  12.3    9.7    9.4    6.5  13.0
9        5.8    5.6    4.7    8.4  11.3  11.0    7.4    4.3

It is statistic file, function of % incoming signals and its elevation angle.


The case is to help with creation real signals density to elevation angle for SP (citiy of Warszawa or Lodz).

*.PRO file is different thing and I got them all for some locations (thanks K6TU):

0.0, 134.6
98.4, 139.0
196.9, 143.0
295.3, 133.5
393.7, 125.0
492.1, 120.6
590.6, 119.0
689.0, 119.2
787.4, 111.9

That PRN file is generated by the OH6BG Elevation-Angle Analyzer (EAA). EAA needs data from VOACAP software. If somebody here is familiar with VOACAP and EAA programs please mail me in case of generate PRN files for SP on most interesting dx/contest directions (US, JA, AF, AS ect).
