I always wonder what someone in the future will think when they dig a hole in the yard and find hundreds of wires and scrap metal everywhere. I like that hidden treasure idea...hi hi Mike WE0H John A
Where there's trees, there's tree fires...Crank up the mad powa until you get rid of those trees...hi hi Mike WE0H Thanks for all the reports and encouragement to continue testing. 73 Scott VE7TIL
I bury scrap metal in my yard all the time. Does it help? I don't know, but it is metal which should be a better conductor for RF than my sand is in my yard...hi hi Mike WE0H I can't remember who it
I'd treat it like any vertical. Radials are required for proper operation. You won't get in any quarterwave radials so they are short and will require the ground pipe at the end to kind of make them
Most people thought a TX loop would not radiate out of a backyard. That was proven very wrong many years ago. The calculations say a TX loop is a terrible antenna, but it does radiate very well. Migh

No doubt. Lots of wire around here. hi hi Mike WE0H a lot of wires up in the air and maybe even more wires dug in the ground ... and still it is called wireless communication ;-) 73, Rik ON7YD - OR7T
I run 11,100 feet of radials for my HF and 600m antennas. It works great but I have lots of wire and lots of time to put them in the ground...hi hi As Mal said, using a good antenna and a few radials
I think connector's that are gold plated are done that way because the general public looks at a gold plated item as high quality. If it was tarnished silver plated, then it wouldn't look so pretty.
Would those Alpha signals be expected to be received in the center of the US or am I too far inland? Mike WE0H I hear the Alpha signals here in Western NA all day every day when they are active. Usua
Maybe it stands for Lost? Possibly some poor chap is out in the countryside loading up a metal sign beside the roadway with his auto tuner trying to summon help...hi hi Mike WE0H M0FMT wrote: Hi all
Correction, Make that .7v p-p input with 150v p-p output with this TV transformer at 8kc. I think it is time to test earth probes as I have too many trees for a vertical on this band. I will try to r
I tried a microwave oven power transformer the other night but it wasn't as efficient as this TV transformer. I couldn't get even 100v out of it with the same input signal that gives me 300v out of t
Running 5.8kc now and getting 300v p-p out of this TV transformer. I turned the VFO dial on the DDS and it showed a peak output from the transformer at 5.8kc. 300v is starting to sound interesting. T
Mal could build a 200kw amp for 8.97kc with a little work...Might melt his antenna or cause a wide spread UK power outage when he hits the key...hi hi Mike WE0H daniele wrote: Hello Ha-Jo, LF, still
Found my Zenith black & white TV chassis tonight. Got a flyback transformer that looks like Litz wound with bees wax for potting compound. No diodes, lots of room for the primary winding that I need
Can someone explain what the TV transformer is and a picture so I can find one here? I was doing testing last night with a DDS VFO into a microwave oven power transformer and got the voltage up enoug
Well worth testing. There might be some other transformers that work and we won't know which ones until someone tests them. Looks like 4kc is the peak of efficiency on that transformer you tested. I
