About the FT-897:
The FT-897D is a rugged, innovative, multiband, multimode portable transceiver for the amateur radio MF/HF/VHF/UHF bands. Providing coverage of the 160-10 meter bands plus the 6 m, 2 m, and 70 cm bands, the FT-897 includes operation on the SSB, CW, AM, FM, and Digital modes, and it’s capable of 20-Watt portable operation using internal batteries, or up to 100 Watts when using an external 13.8-volt DC power source.

ISO 10534-1:1996, Acoustics – Determination of sound absorption coefficient and impedance in impedance tubes – Part 1: Method using standing wave ratio

Specifies a method for the determination of the sound absorption coefficient, reflection factor, surface impedance or admittance of materials and objects. The values are determined by evaluation of the standing wave pattern of a plane wave in a tube, which is generated by the superposition of an incident sinusiodal plane wave with the plane wave reflected from the test object.

BACKSCATTER – interactive visuals, music, performance by Wetcircuit (Holly Daggers). Premiered at ReVISION by Forward Motion Theater January 14th, 2011 Backscatter technology is used by the TSA — a division of Homeland Security — to perform random full-body scans of airline passengers. The scanners create “ionizing radiation”, X-rays powerful enough to strip molecules in the body of their electrons. Charged particles launch from the skin back into the scanner, producing a ghostly nude image that is literally created from body matter. Fourth Amendment rights are forfeit when passengers consent to the search.

Testing of a newly-built 160 metre AM transceiver at Chelsea on Port Phillip Bay near Melbourne. The receiver featured in a previous video. The transmitter is similar to the one presented here: www.angelfire.com It is crystal controlled on 1843 kHz. A centre-tapped 15 volt 1A power transformer is used for modulation. Efficiency is quite high – total Tx power consumption is 1A for approx 7 watts out on peaks. The IRF510 final stage does however need to be presented with an acceptable antenna impedance otherwise distortion can appear on the output, as happened here (the switched inductor in series with the antenna has since been replaced). The transmitter’s circuit is described in ‘Lo Key’ September 2011 – published by the CW Operators QRP Club.

This tech has been around for a while, but with DHS making more grants to local police departments in the next 24 months, you need to be aware of this. Uses for this tech allow the police to see what you have. Whether they use it to peek at what you own as a ‘preview’ in preparation for requesting a warrant, assuming they go through those motions, would allow them to add additional details to the warrant… again, assuming that they do that. So many agencies today don’t even bother because the Constitution is being ignored wholesale, especially by federal agencies. Suppose the ATF uses this to scan your conveyance, your domicile, your storage shed or garage. The abuses of this agency is not merely legendary, it is infamous. Did you buy your guns privately (without papers), or through proper channels? If you did it privately so as to avoid registration (which is legal in many states), ATF may have a ‘heightened interest’ in your property. This van’s stated capabilities also include scanning for specific elements such as nitrogen and oxygen, or sulfur, or aluminum, or silver or gold. Should the government know whether you have silver/gold coin? Should the government know if you own machine tools such as a lathe? Or whether you make things using press-form technology and powdered aluminum, etc? The purpose of this technology is to identify private citizens who possess the resources, materials, and equipment that would be valuable to a resistance movement. This technology is

On this video we talk about the final modifications my good friend Colhane or Mac has done to my Ontario Pilots Survival Knife to improve its bushcraft performance. Those modifications include grounding off the upper hand guard to allow me to choke on the blade, for instance, and the reprofile of its blade into the convex edge. That gives me a sharp and easy-sharpening tool yet with enough metal on the blade to take harder punches such as havier batonning, which cant be done using the Scandi-grind without the risk of damaging it. I owe it all to my friend Mac, who knows A LOT about cutelary and sharpening, re-profiling blades and metal tools! It´s really great to have the chance and the privilege to (finally!!) learn from such a skillful man how to put a good descent edge on my blades, a basic, crucial bushcraft skill yet a very difficult one to be acquiered by many bushcrafters and outdoor people out there (me included!)!

Having a Marine radio can be critical when operating a boat on any type of water. There are many uses for a Marine radio, but the most important is to send a distress signal — here’s how to do it. To complete this how-to, you will need: Boat Marine radio Nautical chart General information about your boat and passengers Call sign and registration number (optional) Compass (optional) Step 1: Call distress signal Tune your marine radio to channel 16 and call out the word “mayday” three times in a row. This is the international hailing and distress frequency. Collect as much information as you can about your vessel, your condition, and your location before making a distress call. Step 2: Name your vessel Call out the name of your vessel by saying “This is” and then repeating the name of your vessel three times in a row. Call out your call sign and registration number once each if you know them. Step 3: Repeat mayday and name Repeat “mayday” and the name of the vessel once more. Step 4: Give position Give the position of your vessel finding your latitude and longitude on a nautical chart, and approximate distance to a known landmark or island. Give your bearing information by describing the direction you’re heading using your compass. Step 5: Describe your condition Describe the nature of your distress by saying something like, “struck a submerged object,” “taking on water,” or “fire on board.” Step 6: Describe what you need Describe any specific assistance you might need
