As long as it acts like a diode it will detect. Need the resonator too. What’s weird is my parents heating ducts would play a local station if the condition was right. Took us ages to figure out where the radio station came from and my dad was a radio guy. Finally traced it to the furnace. Faint but legible. In the early 1930’s WABC (I think) in Chicago advertised they had 1 million watts. People’s gutters were singing and they could hear it in Japan. It’s where the limits on power and the reduction at night came from to reduce skip.
Also when sealing do not use regular silicone, as the acetic acid it releases during cure will eat the metal away. A cheap one I found is the silicone sold to attach mirrors, which is acetoxy free, and often the same price as the regular silicone, but has no vinegar odour. Yes fill them with some grease, and then tape, preferably self amalgamating tape, overwrapped with 3M 33 tape, and that then held at the ends with a cable tie. Even outdoor rated cable degrades, so protect as much as possible from sun, or make sure inside to put in something, like a splitter terminated on the tap off port, preferably a 10dbB line tap with DC pass through, to prevent water coming in the cable from destroying the STB or TV set. Extra 1dB of loss on the line, but better than having to replace the STB in addition to the cables later on. Or just a non waterproof barrel connector and a flylead, low as possible, to make a drip loop, as the barrel will rot out first, hopefully before the water makes it all the way back up.
A guy at a place I used to work had his disk drive lose data. We replaced the drive an it happened again. I started looking around. and found a large transformer bolted to the other side of the wall. The guy didn't want to move his desk, so I told him I guess he didn't need his data.
That only told you that it was losing spark and a cheap spark tester would give you the same result. Also, due to the year of the vehicle, it’s almost always going to be loss of ignition when a) it shuts off like you switched off the key (as opposed to chugging before it stalled) and b) when it fails to fire up right away. Carbureted engines don’t stall like that due to fuel starvation issues and mechanical problems are usually permanent (no restart at all). That just leaves ignition failure with the module and the pick up coil being the most likely root cause(s).
You have an old Ford, 1980s. I could have told you the module was the problem, it was nearly always the module. Make sure to install the new one with heat sink grease. It will delay the failure, but it will fail again.
When I removed the old module I noticed all of the heat sink grease compound on the old module had dried up. What made this repair challenging, was that the motor stalling issue was intermittent, and when the motor was cool the truck ran fine.
This is a complete waste of time. You can just use the lnb on the dish and connect it to a reciever or tv instead of something that will fall apart in 2 days
@GrantsPassTVRepair I used a dish network satellite and I got plenty of channels then I added a rca indoor antenna amplifier and now I have great signals
fun fact: hospital equipment (mri) was relocated in Sydney Australia when the new tunnel was built. the underground activity was throwing of the accuracy of the sensitive diagnostic devices. they were prepared and had already built a new hospital campus specifically for this reason.
I was a telco contractor for 15 years and jumped over to coax about 3 years ago. I found that fiber ONTs seemed to be polarity sensitive when using porting switches. And the cable co's port switches are even more finicky.
Those were used in the medical equipment I used to troubleshoot. They will 'spark' and discharge excessively high voltage. They were used to protect the front-end of EKG circuitry. Terry
I remember seeing them in antique radios, and I've seen them blow up when they reach their threshold voltage if they don't have a resistor in series with their input voltage.
I'm pretty sure this happened to a content creator. They were one day recording videos when their friends heard people in his back ground and asked him if anyone was around. He said ,no but they thought he was lying. Apparently, his mic was picking up radio signals because there was a radio tower close to his home
I am wondering if you know for fact that an dipole antenna which is 1 1/4 times the frequency length has a gain of 5.3 dBi ?? I saw this on a web site some time ago. What do you think Grant from your experiments ?? Interesting video showing cause and effect of signals
The rubberized tape is good, but I've seen it deteriorate in the sun, so I think it would be wise to put an extra few warps of regular electric tape on the outside of it.
By hooking up an oscilloscope to a solar panel you can "decode" and listen to the radio station being broadcast through the LED light. The basis of Lifi, like wifi but with light.😊
Good stuff... but what are the most common causes of vcrs eating tapes? Cleaning heads is good but I came here to figure out why mine's got an appetite
Well, electromagnetic fields extend to the whole universe at the speed of light. So there's no limit to how far a magnetic field can go. You can be certain than right now, at 5 month.light away from Earth it's felt !!!
I learned this one in middle school. We did an electronics engineering project where we attached a laser to an amplified audio source and placed it in the school gym, then used mirrors to direct the beam from the gym, across the cafeteria, through several hallways, and into an optical receiver on the other side. It took forever to get all the mirrors lined up, and once we did, a student bopped one with his foot and we had to line them up again.
