Yves - Congratulations! I know how much effort it is to do such a
thing. We tried a 20 mile LOS contact in bright daylight last weekend
but were not successful. The haze was so bad we could not see the
other mountains at all for pointing. I thought we might make it
since we have so much power available but it seems in daylight
we just lose the margin which makes it easy at night to find the
signal. A quick test here seams to indicate the noise floor rises by
at least 30 dB in daylight while the maximum signal stays the same. I
guess we will have to go back to night time operations until we have
good matching filters. I just ordered another pair of filters from
the same person you suggested on Ebay. Unfortunately the filters are
still only 30 nm HPBW so we may drift out of band with
temperature. Do you have any feel for how much the noise floor rises
in your system with daylight? Keep up the great work and thanks for
sharing with us.
