Re: [amsat-bb] AO-40 - TONIGHT's The NIGHT!

["hasan schiers" <schiers@xxxxxxxxxx>]

Me too...first time to try to transmit this evening. I spent this morning
putting a 22 el k1fo 70cm yagi on my cross boom 5 feet off the ground, next
to my 39" HyperLink Dish and UEK 3000 downconverter. I have about 5 dB of
coax loss on TX.

I ran out a little spreadsheet chart from ao40.xls This is how it looks for
me in central Iowa tonight:

Time    Az        El    SQ    Amp Output Pwr to Trigger Liela-1

0235    204    35    36.1    > 100 w; 100w =15 dB SNR
0250    197    39    26.0    59w
0300    195    41    20.9    73w
0315    193    43    15.0    36w
0330    192    44    10.4    34w
0345    193    45    06.7    38w
0400    194    46    03.6    19w
0415    195    46    01.0    46w
0430    197    46    01.3    53w
0445    200    46    03.4    60w
0500    203    46    05.2    68w
0530    209    45    08.4    89w (Trees start at azimuth 210)
0600    215    43    11.1    >100w 100w=16.6 dB SNR
0630    221    41    13.5    >100w 100w=14.9 dB SNR
0700    227    38    15.7    >100w 100w=13.2 dB SNR

I have a hard limit of trees at 210 degrees, so it looks like I should have
from 0230 to 0530 to use the bird, and the time from 0300 to 0415 Azimuth
stays within 3 degrees and Elevation within 5 degrees, so I might actually
be able to talk to someone, if my K1FO yagi that has been laying in the
weeds for the last two years actually works <g>

Otherwise it will be a FUN night to listen.
