Hi John, What did you use as the P3 bandwidth for your noise measurement? And conversion to 1Hz equivalent. The P3 has its own bandwidth and is not affected by setting the receiver bandwidth. Lee K7TJR OR
(Note: what follows is a long, technical discussion about noise and “small” antennas. I invoke some math and physics here, so if you are not comfortable with it, feel free to disregard or delete this e-mail. I went through this exercise to help teach myself the limits here and maybe others might find it helpful or educational as well.) _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
