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.
