[Laser] more XE2AT

[Alvaro de Leon Romo]

Dears friends, first all many thanks for all helps from all of you !!!
I used for a 1km test the Ramsey kit on both sides with 4 inches lens and 
the voice test was OK , so I test another TX the K3PGP diagram witha 555 and 
work FANTASTIC very loud.
With this test I made the test at 25 km ( checked distance today ) , I used 
the RX system on both sides 4 inches lens and the CW TX, we spend a lot of 
time looking for the Laser of my partner because the bad allignment of my 
pointer until finally BOTH we can see the Lasers , great and fantastic view 
at 25 km.
I use the Ramsey RX system on both sides but nil my partner or me we can 
heard the Laser noise. I beamed the Rx system to the lights of the city 18km 
apart and I canot heard noise , nothing , nothing.
So I think the problem is the sensity of the LED of Ramsey circuit, I will 
do a 5 km test with lens and no lens and I will give the info.
Many thanks for the all info....
