Tap/Knock code communication
I saw this on the net today and I think it’s a great idea. Personally I use Morse code, But this limits me in two ways. 1. I need a electronic medium to transmit over great distances. 2. The person receiving the message needs to know Morse code. With his you could easily use a light or any noise maker. Here is the Wikipedia page on it. https://en.wikipedia.org/wiki/Tap_code Here is…

This presented a problem when using a USB sound card for a interface. the universal ground what shorting the two leads. so we need to make a ground loop isolator and set the radio to VOX. not…
Homebrew Temporary lightning arrestor
In the past I have just used spark plugs too. How it works: Once the air has ionized, it becomes a conductor. And the dielectric breakdown of the air makes it a conductor and will pass the static charge/lightning strike to ground. Its kind of a one shot deal and it’s better than nothing. Its mostly for the static build up on the wire in the storm. Sharpened…
How to Solder copper wire to aluminum foil.
How to Solder copper wire to aluminum foil. I will be making some disposable variable capacitors later today for some magnetic loop antennas. This is also a useful technique to solder copper braid to an antenna. I think you can use any oil. the important thing to remember is keeping Oxygen form the foil. You don’t want it to oxidize before you get the solder down.
SHTF Survivalist Radio Frequency Lists
I have seen a lost of copies of a list like this over the years. However I think this is the best one with all the other channels. I want to make a personal note here: Its important to get your ham license before the S.H.T.F. Its very unlikely you will be able to use ham equipment with out the proper knowledge or experience to deal with RFI or Propagation….
