My 6m setup is not the greatest. I have a beam in the garage, but to put that up means moving the HF antenna, so it will have to wait for the better weather.
Yes, I had just tried the ant vs dummy load comparison. The noise level increases with the antenna connected, but whether that is due to band or local electrical noise I can't be sure. It is probably that I have got used to seeing a significant noise reading on the S meter on the bands below 30MHz ! 73 Stewart G3RXQ On Mon, 24 Mar 2008 12:19:46 +0000, Brendan Minish wrote: > In my quiet rural location with a 7 element long yagi fed with feeder > totalling about 0.5dB of feeder loss, I find that the K3 is sensitive > enough (just) to hear to the band noise floor. > My Icom 7800 was more sensitive on 6m (& a superb 6m radio in general) > but since the K3 is sensitive enough to hear to the band noise floor I > suspect that adding a premap in my case is not going to help. > Eavesdropping on EME QSO's ( i have yet to do EME on 6m with the K3) > seems to indicate that the in my setup adding a preamp is going to make > little or no difference. > > A simple test is to compare the noise level of a Dummy load with the > noise level received on an antenna.
