What I think you are observing is the AGC bringing up the system gain so that you hear circuit noise in the front end. As W8JI has often observed, if the noise level increases at least 10dB when you connect the antenna, the circuit noise in the receiver is not limiting weak signal performance. That condition is met on all bands except 6M, where an external preamp is needed in any reasonably quiet location. 73, Jim Brown K9YC ______________________________________________________________ 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
