I live in a neighborhood that as the years have gone on has added a number of new homes. This has increased the electrical "noise" for me where S1 or S2 on 80 meters 6-8 yrs ago is now S7 to S9. At this point in time I don't have the room for a K9AY setup. I can only "dream" of a beverage. I have a Timewave ANC-4 which works very well on 40 meters as I can null out ALL the "noise". Not so on 80 meters as it only knocks it down 2 S Units. At best I have an S-6 noise level. This leads me to believe that I need a separate sensing antenna for 80 meters. Anyone have any ideas for this problem? Is this thinking correct? I have been looking at low noise receiving loops and other low noise antennas. Wellbrook athttp://www.wellbrook.uk.com/seems to have some interresting possibilities, but some of the reviews I have read have made me hesistant to purchase any of their products. What I need is some serious input from anyone who has any experience and knowledge in dealing with low band noise issues. As I am now space limited due to all the new neighbors any solution would need to take this into consideration. TIA Just out of curiosity, have you tried locating the noise source. I had the same experience you are having more or less. I had been away from ham radio for a couple of years and when I fired it all up again HF was really noisy so I ran the radio off of battery while I shut down power to my house. I found the source of the noise was the display on my microwave oven. Short term solution was keeping the microwave unplugged until needed. Long term solution was replacing the microwave. I did this when i found a better one at Goodwill for less than $20. Also check for RF on the coax during transmit. During rx this means the antenna is also picking up signals from the shield which may be in close proximity to noise generators. Jimmie |
