Dave, I agree with your math, except... Having a noise level of -27dBm delivered by the transmitter to the antenna system, does not mean the antenna has 100% radiation efficiency, yes?
So -27dBm is 2 microwatts in transmitted noise to the antenna system, at this particular spacing, in a 500Hz bandwidth. You must make some allowances for not only path loss, but antenna efficiency on each end, yes? As I said, I am not trying to defend these performance (or lack thereof) claims. I just disagreed with the statement that the "Flex is transmitting wideband S9+45 noise" "S9+45dB" is a receive measurement, not a transmitter measurement. The Flex is sending 2 microwatts to the antenna at the frequency in question. Admittedly, that's too much, in many situations. Peace, Bruce N1RX ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
