Thanks to all the replies from actual "ground independent loop" antenna users. There are many reduced lot size users who are working a lot of DX and hearing quite well. My questions were to find what
Thinking of carbon fiber for your next 160 meter project? Listed are material advantages & disadvantages. http://www.protechcomposites.com/pages/About-Carbon-Fiber.html 73 Bruce-K1FZ www.qsl.net/k1fz
The on-off timing may suggest a timer applying power to a power leaking hot water heater. 73 Bruce-K1FZ The noise occurs early AM, before sunrise. It was gone during the day and early evening yesterd
-9 f. Most DXers know that tap water water is not chemically pure. Got a reminder yesterday. I turned the water on, then got an item from a very close storage area. Returning I put my hand to the run
Our ever changing Earth's magnetic field. How could it not effect 160 meters? http://www.youtube.com/watch?v=pGKKzsRjJ_Y 73 Bruce-K1FZ _________________ Topband Reflector Archives - http://www.contes
No power here yet. Yesterday 75 % of Belfast residents without power, today 50%. Large number of power line-men from all over now here to give up their Christmas to help those with out heat. Antenna
High solar activity not only affects 160 meter propagation, but Sam Beverage, a relative of Harold Beverage, has noted a polar freezing connection. 73 Bruce-K1FZ On another subject, this one Sun-Spot

Hi Charlie, A little cross multiplication shows that if you had 600 volts when the primary is 110 VAC, then with 130 primary volts you should have 709 Volts. A larger increase takes place between cho
Why did so many polar expeditions take place in periods of high solar activity ? Did they believe that sun spots would result in higher earth polar temperatures? They found quite the reverse was true

There was a article in the June 1953 QST Page 47, that used a BC-457 as a high level mixer into the 1625's to get on 40 meter SSB from 4 MHZ. On Page 47 there is a diagram for the W2JJC SSB exciter u
Hi Charlie, The HT-32 project took place at a TV station where I worked. They had a well equipped work shop at the transmitter site. I had some idle time each work day to build and test. Great on bui
Years ago when I did in my MFJ meter, 50 ohms was reading 40 ohms. It was a real chore to change out the bad diode and calibrate. 73 Bruce-K1FZ www.qsl.net/k1fz/pennantnotes.html After making all of
From my notes, it was diode D3. (May not always be the same) I got the calibration info from a W8JI WEB site posting. http://www.w8ji.com/mfj-259b_calibration.htm 73 Bruce-K1FZ www.qsl.net/k1fz/bever
Getting noise from my NW direction. Does not seem to be local. Started wondering what, at distance, could be causing it. At times it seems to have a rhythm like a motor. There are a lot of power gene
Hi Jim, Noise may be riding on the power lines. Try to drive a good distance away from them for a test. A leaking transformer with a bad pole ground can do it. Power companies will usually be coopera
Hope for cloudy days after the ice build up. Towers often fail when the sun heats the south guy wires. When the ice drops off rapidly, the weight on the north guy wires can pull the tower over. 73 Br
Jim, Think of a cage connection rather than a single wire to a shunt fed tower and its benefit. The cage larger diameter causes an impedance change and also makes it a more broad-banded fat conductor
