[Laser] daylight receiver

[Andrew T. Flowers, K0SM]

Does anyone have a design for a good daylight receiver?  My K3PGP front 
end won't hear much in daylight.  I'm not looking for something that is 
super sensitive--just good enough for a LOS QSO on a sunny afternoon.  I 
was thinking about putting the RX in a black box and using a very small 
lens, thus limiting the amount of total light hitting the surface.  I 
may also try using a low-value resitor on my OPT310 RX to widenthe BW 
and decrease the gain.  Right now it makes a pretty good oscillator if 
you hit it with the laser directly :-)

( and yes, I'm too poor to to afford narrowband filters)
